PRICAI is a biennial conference inaugurated in Tokyo in 1990. It provides a common forum for researchers and practitioners in various branches of artificial intelligence (AI) to exchange new ideas and share experience and expertise. Over the past 26 years the conference has grown, both in participation and scope, to be a premier international AI event for all major Pacific Rim nations as well as countries from further afield. This year marked the first time that the conference was held in Thailand. In addition to the main track, PRICAI 2016 featured a special track on Smart Modelling and Simulation. This year, we received 161 high-quality submissions from 25 countries to both the main and special tracks. From these, 53 papers (33%) were accepted as regular papers, with a further 15 accepted as short papers. Each submitted paper was considered by the Program Committee members and external reviewers, and evaluated against criteria such as relevance, significance, technical soundness, novelty and clarity. Every paper received at least three reviews, and in some cases up to four, supplemented by rigorous discussion among the reviewers. Finally, the program co-chairs read the reviews and discussion among reviewers, and made the final decision to ensure fairness and consistency in the paper selection. The technical program began with two days of workshops and tutorials, followed by the main conference program. The workshops included the Pacific Rim Knowledge Acquisition Workshop (PKAW), co-chaired by Hayato Ohwada (Tokyo University of Science, Japan) and Kenichi Yoshida (University of Tsukuba, Japan), which has long enjoyed a successful co-location with PRICAI. Authors of short papers presented their results during poster sessions, but were also given opportunity to give shortened talks to introduce their work. As in previous years, participants at PRICAI were also able to attend the co-located 19th International Conference on Principles and Practice of Multi-Agent Systems (PRIMA 2016). We were honored to have three outstanding keynote speakers, whose contributions have crossed discipline boundaries: Phan Minh Dung (Asian Institute of Technology, Thailand), Sheng-Chuan Wu (Franz Inc., USA) and Zhi Hua Zhou (Nanjing University, China). We are grateful to them for sharing their insights on their latest research with us. It would not have been possible to organize the technical program without the considerable help of various people who committed their time and effort towards making 5 PRICAI/PRIMA/PKAW 2016 Program Book PRICAI 2016 a success. We would like to thank the Program Committee members and external reviewers for their engagements in providing rigorous and timely reviews.

Started as an Asia-Pacific workshop in 1998 and run as a full conference since 2009, PRIMA has become one of the leading and influential scientific conferences for research on multi-agent systems. Each year, PRIMA brings together researchers, developers, and practitioners from academia and industry to showcase research in several domains, ranging from foundations of agent theory and engineering aspects of agent systems, to emerging interdisciplinary areas of agent-based research. Previous successful editions were held in Nagoya, Japan (2009), Kolkata, India (2010), Wollongong, Australia (2011), Kuching, Malaysia (2012), Dunedin, New Zealand (2013), Gold Coast, Australia (2014), and Bertinoro, Italy (2015). The 2016 edition was a special one for a number of reasons. One, to foster a larger Asia Pacific community, it was co-located with the 14th Pacific Rim International Conference on Artificial Intelligence (PRICAI 2016). Two, to foster interdisciplinarity, we ran a social science track, whose accepted papers will be fast-tracked into the Journal of Artificial Societies and Social Simulation. Three, to foster student participation, we ran a special student session track. Student authors of accepted papers received free registration for the conference. We received 50 full paper submissions from 22 countries. Each submission was carefully reviewed by at least three members of the Program Committee (PC) composed of 107 prominent international researchers. The review period was followed by PC discussions moderated by Senior Program Committee (SPC) members. The PRIMA SPC has been part of the PRIMA reviewing scheme since 2010, and this year it included 21 members. At the end of the reviewing process, in addition to the technical reviews, each paper received a summary metareview by an SPC member. The PC and SPC was truly international, involving researchers from 28 countries. PRIMA 2016 accepted 17 full papers, giving an acceptance rate of 34%, 16 papers are included in this volume. Moreover, the volume contains three extended abstracts, accepted for the presentation in the social science track, and nine promising early innovation short papers. Further, we accepted seven submissions for the student session track.

August 2016 PRIMA General Chairs Katsutoshi Hirayama, Kobe University, Japan Paolo Torroni, University of Bologna, Italy PRIMA Program Chairs Matteo Baldoni, University of Torino, Italy Amit Chopra, Lancaster University, UK Tran Cao Son, New Mexico State University, US 8 PRICAI/PRIMA/PKAW 2016 Program Book Welcome Message from the PKAW Workshop Chairs This volume contains the papers presented at PKAW2016: The 14th InternationalWorkshop on Knowledge Management and Acquisition for Intelligent Systems, heldduring August 22-23, 2016 in Phuket, Thailand, in conjunction with the 14th PacificRim International Conference on Artificial Intelligence (PRICAI 2016).In recent years, unprecedented data, called big data, have become available and knowledge acquisition and learning from big data are increasing in importance. Varioustypes of knowledge can be acquired not only from human experts but also from diversedata. Simultaneous acquisition from both data and human experts increases its importance. Multidisciplinary research including knowledge engineering, machine learning, natural language processing, human-computer interaction, and artificial intelligence is required. We invited authors to submit papers on all aspects of these area. Another important and related area is applications. Not only in the engineering field but also in the social science field (e.g., economics, social networks, and sociology), recent progress in knowledge acquisition and data engineering techniques is leading to interesting applications. We invited submissions that present applications tested and deployed in real-life settings. These papers should address lessons learned from application development and deployment. As a result, a total of 61 papers were considered. Each paper was reviewed by at least two reviewers, of which 28 % were accepted as regular papers and 8 % as short papers. papers were revised according to the reviewers’ comments. Thus, this volume includes 16 regular papers and five short papers. We hope that these selected papers and the discussion during the workshop lead to new contributions in this research area. The workshop co-chairs would like to thank all those who contributed to PKAW 2016, including the PKAW Program Committee and other reviewers for their support and timely review of papers and the PRICAI Organizing Committee for handling all of the administrative and local matters. Thanks to EasyChair for streamlining the whole process of producing this volume. Particular thanks to those who submitted papers, presented, and attended the workshop. We hope to see you again in 2018.

The workshop is honored to have Associate Professor Kenji Tanaka, M.D., Ph.D. from the Department of Neuropsychiatry of Keio University School of Medicine. This is the first time a brain expert will be delivering a talk at IWEC. The workshop received a number of papers from all over the world. Each paper was reviewed by international experts in these fields, and only 50% of the submissions were accepted as full papers. The papers accepted to the workshop range from processing physiological signals, to the effects of emotion during a student’s learning episode, as well as understanding emotional laughter expressions. The participants will learn a breadth of modalities, how these are processed, and how emotions and its expressions play a large part to make user experiences worthwhile. The worshiop organizers would like to thank all the advisers and the members of the program committee, including all the authors who submitted papers. In addition, we would like to thank the PRICAI Organizers for their support to IWEC-16. We look forward to a successful workshop.

AI technologies and applications have truly entered our everyday lives, with AI systems in use throughout society. Against this backdrop of AI’s remarkable success, the First International Research Student Symposium on the Artificial Intelligence and Application (RAI-2016), to be held in Phuket, Thailand between 22 and 26 August 2016, is the first time the flagship international AI conference has been held in Kingdom of Thailand, and provide the opportunity for Master Students and Ph.D. candidates and researchers to share and discuss on research work and idea. These proceedings collect some of the most exciting research taking place in AI today and offer a window into the future. The theme of the workshop this year is “Artificial Intelligence and Application.” Being held in Phuket, the Pearl of Andaman Ocean, the RAI workshop will feature invited talks, performances and a technical track dedicated to the exploration of AI’s growing role in Application and research update, both in enriching and producing AI work and injecting AI into application to make it an elegant and more accessible scientific discipline. All accepted papers are included in these proceedings and are invited to present in workshop sessions and posters. Authors of all papers are invited to give oral presentations, where a distinction is made between long talks and short talks based on the papers’ quality, clarity, and potential relevance to a wider audience. The Program Committee did a thorough and highly professional job in reviewing all papers submitted to the conference. Every paper received at least two reviews, which were provided by members of the program committee (PC). The review process for each paper was overseen by at least one senior program committee (SPC) member, who monitored reviews and initiated discussion before and after the author feedback period. Each paper was also managed by the workshop chairs (WC), who engaged in discussions and gave recommendations on the final decision based on the PC and SPC input. During the review process, author feedback was taken into account for the final discussion. When necessary, additional reviews were obtained. Finally, Workshop Chairs, PCs, SPCs and the Reviewers worked closely in making the final decisions. The end result is a RAI-2016 program of outstanding quality. We wish to express our deep appreciation to the Workshop Chairs and Program Committee Members for their outstanding and very professional organization of the review process. 14 PRICAI/PRIMA/PKAW 2016 Program Book We also wish to express our sincere thanks to all reviewers for their valuable dedication. Our deep gratitude extends to the organizers of many other workshop programs of the PRECAI-2016 conference. We are indebted to their great effort and professionalism. The conference organizing committee provided the much-needed support for the review process. Finally, we wish to thank all authors of submitted technical papers for contributing to this great RAI Workshop Symposium. With your high quality work and devotion, RAI will continue its tradition of excellence and leadership in advancing the Artificial Intelligence Application for the upcoming Symposiums in future..

A complex system is featured with a large number of interacting components, whose aggregate activities are nonlinear and self-organized. Complex systems are hard to be simulated or modelled by using traditional computational approaches due to the complex relationships of components and distributed features of resources, and dynamic work environments. Meanwhile, smart systems such as multi-agent systems have demonstrated advantages and great potentials in modelling and simulating complex systems. The special track on Smart Modelling and Simulation (SMS) under the PRICAI’16 will bring together researchers in both artificial intelligence and system modelling/ simulation to discuss research challenges and cutting edge techniques in smart simulation and modelling. We hope to provide opportunities for not only AI researchers, but also domain experts who are interested in the applications of AI techniques in system modelling and simulation. We look forward to seeing all of you in Phuket.

Because intercultural collaboration is a new area with scarce data, it was necessary to execute parallel experiments in both in real fields as well as in research laboratories. In 2002, we conducted a oneyear experiment with Japanese, Chinese, Korean and Malaysian colleagues and students to develop open-source software using machine translation. From this experiment, we understood the necessity of language infrastructure on the Internet to create customized multilingual environments for various situations. In 2006, we launched the Language Grid project to realize a federated operation of servers for language services. So far, four servers have been set up in Asia, and more than 200 language services have been registered from 22 countries. Using the Language Grid, we have been working with an international NGO for four years to support communications between rice harvesting experts in Japan and farmers and their children in Vietnam. During these experiences, we gradually understood the nature of intercultural collaboration and we faced different types of difficulties. Problems are “wicked” and not easily defined because of their nested and open networked structure. For example, technologies supporting collaboration are often successful when we weaken cultural differences; cognitions of cultural differences are different in different cultures, etc. In this talk, we view intercultural collaboration as a research in human-aware multiagent systems with the goal to encourage researchers in multiagent systems to stand by intercultural collaboration. We believe a human-aware multiagent research can contribute solutions to real-world complex problems. 77 PRICAI/PRIMA/PKAW 2016 Program Book Biography Toru Ishida has been a professor of Kyoto University since 1993.

Keynote: Monday, August 22 (09:00 - 10:00) Ballroom B 78 PRICAI/PRIMA/PKAW 2016 Program Book Two PRIMA Keynote/Invited Speakers Agent-based modelling and simulation for co-operative traffic and transport Jörg P. Müller Department of Informatics, Clausthal University of Technology Email: [email protected] Recent developments in Car-to-X communication networks, advanced assistance functions, and autonous vehicles create new prospects for Intelligent Traffic and Transport Systems (ITS): Traffic Information Systems may benefit from real-time information provided via cooperative sensing; autonomous vehicles can interact and perform cooperative driving maneuvers, aiming at improving traffic safety, traffic efficiency, and user comfort; traffic management may provide individual route guidance and electronic road pricing mechanisms to influence the behaviour of (automated and human) traffic participants towards societal goals. However, the autonomy of traffic participants makes analysing, predicting, and managing future ITS a very difficult problem, creating challenges for next-generation traffic management systems, requiring new cooperative approaches, enabling us to reconcile the concepts of user optimum and system optimum, respec- tively. Starting from the notion of co-operative, (de-)centralized traffic management, I advocate the multiagent paradigm for modeling and simulation of future traffic systems. I report on experiences with a multi-agent based approach for cooperative traffic management and autonomous vehicle scenarios. I sketch the underlying conceptual paradigm and architecture, exemplify the use of game-theoretic and computational social choice methods in the traffic application domain, and report on ongoing work geared towards platforms supporting scalable multi-agent based simulations. 79 PRICAI/PRIMA/PKAW 2016 Program Book Biography Prof. Dr. Jörg P.

Keynote: Tuesday, August 23 (09:00 - 10:00) Ballroom B 80 PRICAI/PRIMA/PKAW 2016 Program Book Two PRICAI Keynote/Invited Speakers Global Data Warming for AI Spring Sheng-Chuan Wu Franz Inc., Silicon Valley, USA. [email protected] The explosion of data may have made AI trendy again. Google has just made their AI chief the head of Google Search, which holds the world’s biggest repository of data. One of the key AI endeavors is knowledge acquisition and discovery. Typically, we turn the data we collect into information by applying its context. We then interpret the information to derive knowledge from it. Knowledge is what provides value to our endeavors, as we believe. Is this paradigm still true with the explosive growth in Big Data? One of the most consequential examples is medical science. Since the sequencing of the human genome in 2003, we have dreamed about treating patients more effectively based on their genomic profiles. Such a dream remains elusive. The fundamental difficulty lies in the complexity of biological systems that have evolved through billions of years. On the other hand, major progress can be and has been made in “personalized medicine” by applying classic AI machine learning on the massive patient medical data accumulated. In essence, we can uncover new knowledge from the data to help patients without knowing the why a priori. Lack of direct value brought forth the last AI winter. Perhaps Big Data will foreshadow the coming spring of AI. Exploiting Big Data brings another set of management problems, namely the heterogeneous nature of data sources and taxonomies, the enormous size of data volume, and huge data analytic processing requirements. We will discuss all these issues and show some examples in healthcare at this talk. 81 PRICAI/PRIMA/PKAW 2016 Program Book Biography Dr. Sheng-Chuan Wu received his Ph.D. in Scientific Computing and Computer Graphics from Cornell University in the US.

We engage in argumentation in almost all of our daily conversations. Much of our knowledge and intellectual skills is learned through argumentation. Can we build humanoid robots that could argue with us and help us improving our own arguing skills? Argumentation is an active field in AI and knowledge representation. A well-known model of an argumentation systems (also known as argumentation frameworks) is a pair (AR,attack) where AR is a set of arguments and att is a binary relation over AR representing an attack relation between arguments. Though very simple, it turns out that this model is general enough to represent many forms of practical reasoning like legal reasoning, common-sense or default reasoning, experimental reasoning (like in medicine). In this talk we will present an axiomatic approach to the theory of argumentation. We begin with a rather light-hearted illustration of the role of argumentation in our daily lives and proceed to present an overview of the principles and properties underlining the theory of argumentation.

Last I will introduce the recent technology, called optogenetics, and will talk optogenetics-mediated approach toward deciphering emotional and motivational circuits in animals. What is emotion? How can we realize our emotional state? Why does emotional response coincide with physical response? Why do depressive patients suffer from decreased motivation? It is difficult to clearly answer them, however, there are several theories to understand them based on the clinical/psychological observations. First I will overview theories regarding emotion. Second I will point out the technical limitation to understand Biography Dr. Kenji Tanaka received his M.D. from Keio University School of Medicine, Japan in 1997 and completed the residency training in the psychiatry department of Keio University Hospital.

In addition, he also undertake non-military projects in different areas, including composite services, logistics, intelligent web, etc., which apply coalition formation concept to tackle the problems. Tutorial Length A four-hour tutorial 88 PRICAI/PRIMA/PKAW 2016 Program Book Objectives and motivation of the tutorial Coalition formation is an interesting area of research in multiagent systems, an important area in artificialintelligence. Since 1994, when the first game theorists, namely John Nash, Reinhard Selten and John Harsanyi, were rewarded the so called Nobel Prize in Economics (The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel), AI communities have been excited about challenges in solving hard problems in Economics, both in terms of complexity and outcomes of non-cooperative games (defined by Neumann and Morgenstern). However, the other types of games, cooperative game or coalition formation is also interesting – there are cooperative game theorists, namely Robert Aumann and Lloyd Shapley, awarded the same prizes in 2005 and 2012 respectively. Coalition formation offers several solution concepts, including Shapley value, Kernel, Core, which can be applied to solve computationally hard problems in real world, including optimization, logistics, combinatorial auction, mechanism design, etc. Although coalition formation is well-known internationally, it is hardly known to Thai AI community and many young researchers. It is a good opportunity for them to disclose this exciting research area. The objective of this tutorial is to give an introductory lecture to coalition formation in AI research. Intended audience Master and PhD students in Computer Science (and interested people). Tutorial outline 1. Introduction to game theory 2. Non-cooperative game 3. Coalition formation 4.

However, a closer analysis reveals considerable similarity in their objectives and in the key units of analysis and representational constructs. Developments in both fields are also complementary in many ways, and each can leverage results from the other. This tutorial will lay out a new synthesis of both approaches. Attendees will take away an appreciation of how agent systems insights can add value in the (already substantial) industrial applications of business process management and how business process insights might make agent systems more amenable for deployment in business/industry settings.

This research field is influenced by micro economics, in particular, game theory. Here, the meaning of a “market” is very broad; it includes a spectrum auction, in which a government allocates the licenses to use specific spectrum bandwidth to companies, or a market without monetary transfer, such as a kidney exchange program, or a school choice program, in which children/ parents can choose public schools they want to attend. Now, market design has become a interdisciplinary research topic that is relevant to computer science and information systems. In this lecture, I will describe two representative application domains of market design: auction mechanisms (e.g., spectrum auctions, sponsored search) and two-side matching mechanisms (e.g., medical resident matching programs, school choice programs). 100 PRICAI/PRIMA/PKAW 2016 Program Book Biography Makoto Yokoo received the B.E., M.E., and Ph.D. degrees in 1984, 1986, and 1995, respectively, form the University of Tokyo, Japan.

Motivated by the need to improve response and coverage metrics in urban environments, my research group is focussed on building intelligent agent systems that make sequential decisions to continuously match available supply of resources to an uncertain demand for resources. Our broad approach to generating these se- quential decision strategies is through a combination of data analytics (to obtain a model) and multi- stage optimization (planning/scheduling) under uncertainty (to solve the model). While we perform data analytics, our contributions are focussed on multi-stage optimization under uncertainty. We exploit key properties of urban environments, namely homogeneity and anonymity, limited influence of individual entities, abstraction and near decomposability to solve ”multi-stage optimization under un- certainty” effectively and efficiently. 102 PRICAI/PRIMA/PKAW 2016 Program Book Biography Pradeep Varakantham is a Lee Kong Chian Fellow and an Assistant Professor in the School of Information Systems at Singapore Management University.

A complex system is featured with a large number of interacting components (agents, processes, etc.), whose aggregate activities are nonlinear and self-organized. Complex systems are hard to be simulated or modelled by using traditional computational approaches due to the complex relationships of components and distributed features of resources, and dynamic work environments. Meanwhile, smart systems such as multi-agent systems have demonstrated advantages and great potentials in modelling and simulating complex systems. We are going to organize a special session on Smart Modelling and Simulation (SMS) under the 14th Pacific Rim International Conference on Artificial Intelligence (http:// saki.siit.tu.ac.th/pricai2016/). SMS aims to bring together researchers in both artificial intelligence and system modelling/simulation to discuss research chal104 PRICAI/PRIMA/PKAW 2016 Program Book lenges and cutting edge techniques in smart simulation and modelling. Smart simulation and modelling is an important field in AI. We believe that this special session will attract attentions from not only AI researchers, but also domain experts who are interested in the applications of AI techniques in system modelling and simulation. The topics of the special session include but are not limited to: · Agent based simulation for complex systems · Agent based modelling for complex systems · Large-scale simulations · Network simulation and modelling · Environment and ecosystem simulation and modelling · Smart Grid/Service simulation and modelling · Simulation of social and economic organizations · Simulation of social complexity · Cooperation, coordination, negotiation and self-organisation in complex systems · Market-based model and simulation · Transportation model and simulation · Crowd model and simulation · Evacuation model and simulation · Simulation and modelling for disaster management · Simulation and modelling techniques in Big Data Special Session: Wednesday, August 24 (13:30 - 17:00) Room Arcadia 1 105 PRICAI/PRIMA/PKAW 2016 Program Book Abstracts 106 PRICAI/PRIMA/PKAW 2016 Program Book PRICAI Abstracts 107 PRICAI/PRIMA/PKAW 2016 Program Book 3-D Volume of Interest Based Image Classication Akadej Udomchaiporn1, Frans Coenen1, Marta Garca-Fi~nana2, and Vanessa Sluming3 1Department of Computer Science, University of Liverpool, Liverpool, UK {akadej,coenen}@liv.ac.uk 2Department of Biostatistics, University of Liverpool, Liverpool, UK [email protected] 3School of Health Science, University of Liverpool, Liverpool, UK [email protected] Abstract. This paper proposes a number of techniques for 3-D image classication according to the nature of a particular Volume of Interest (VOI) that appears across a given image set. Three VOI Based Image Classication (VOIBIC) approaches are considered: (i) Statistical metric based, (ii) Point series based and (iii) Tree based. For evaluation purpose, two 3-D MRI brain scan datasets, Epilepsy and Musicians, were used; the aim being to distinguish between: (i) epilepsy patients versus healthy people and (ii) musicians versus non-musicians. The paper also considers augmenting the VOI data with meta data. According to the reported experimental results the Point series based approach, augmented with meta data, is the most effective.

Concurrent Multiple Negotiation (CMN) mechanism is necessary for agents to achieve agreements in multiple negotiations, and it has become a very important research topic in multi-agent systems in recent years. However, in the open and dynamic negotiation enviroment, negotiations may be dynamically and concurrently initialized or terminated during the process of other existing negotiations. Therefore, how to process dynamic CMN becomes a serious challenge in agent negotiation research. The motivation of this paper is to propose an adaptive mechanism for handling dynamic CMN by considering the possible changes of concurrent negotiations. First, a formal mechanism for modeling and representing dynamic CMN is presented. Then, a novel Colored Petri Net-based CMN protocol for processing CMN with unexpected negotiation changes is presented. We also demonstrate the performance and procedure of the proposed approach in handling the dynamism of negotiations in CMN, and the experimental results show that the proposed approach can effectively handle unexpected changes in the CMN dynamically, and successfully lead the CMN to agreements. 109 PRICAI/PRIMA/PKAW 2016 Program Book A Differential Evolution Approach to Feature Selection and Instance Selection Jiaheng Wang, Bing Xue*, Xiaoying Gao, and Mengjie Zhang School of Engineering and Computer Science Victoria University of Wellington, PO Box 600, Wellington 6140, New Zealand [email protected] Abstract. More and more data is being collected due to constant improvements in storage hardware and data collection techniques. The incoming flow of data is so much that data mining techniques cannot keep up with. The data collected often has redundant or irrelevant features/instances that limit classification performance. Feature selection and instance selection are processes that help reduce this problem by eliminating useless data. This paper develops a set of algorithms using Differential Evolution to achieve feature selection, instance selection, and combined feature and instance selection. The reduction of the data, the classification accuracy and the training time are compared with the original data and existing algorithms. Experiments on ten datasets of varying difficulty show that the newly developed algorithms can successfully reduce the size of the data, and maintain or increase the classification performance in most cases. In addition, the computational time is also substantially reduced. This work is the first time for systematically investigating a series of algorithms on feature and/or instance selection in classification and the findings show that instance selection is a much harder task to solve than feature selection, but with effective methods, it can significantly reduce the size of the data and provide great benefit. Keywords: Differential Evolution; Feature Selection; Instance Selection; Classification 110 PRICAI/PRIMA/PKAW 2016 Program Book A Microblog Hot Topic Detection Algorithm based on Discrete Particle Swarm Optimization Huifang Ma, Yugang Ji, Xiaohong Li, Runan Zhou College of Computer science and engineering, Northwest Normal University [email protected] Abstract. Traditional hot topic detection algorithms cannot show its optimal performance on microblogs for their inherent flaws in constructing short-text representation model, implementing the core algorithm in large corpus with short time and evaluating the algorithms’ qualities during the process of detecting hot topics. In this paper, a novel method for detecting hot topics in microblogs is presented. This approach takes advantage of a probabilistic correlation-based representation measure in order to ensure a dense and low-dimension microblog representation matrix. Besides, we take the clustering as an optimization problem and introduce a discrete particle swarm optimization (DPSO) to simplify the clustering process to detect topics. Furthermore, the clustering quality evaluation criteria is adopted as the optimization objective function for topic detection which can evaluate the algorithms’ qualities after each iteration. Experimental results with corpora containing more than 148,000 twitters show that our algorithm is an effective hot topic detection method for microblog.

Sabar, Ayad Turky and Andy Song School of Computer Science and I.T., RMIT University, Australia {nasser.sabar, ayad.turky, andy.song}@rmit.edu.au Abstract. This study investigates the dynamic shortest path routing (DSPR) problem in mobile ad-hoc networks. The goal is to nd the shortest possible path that connects a source node with the destination node while effectively handling dynamic changes occurring on the ad-hoc networks. The key challenge in DSPR is how to simultaneously keep track changes and search for the global optima. A multi-memory based multi-population memetic algorithm is proposed for DSPR in this paper. The proposed algorithm combines the strength of three dierent strategies, multi-memory and multi-population and memetic algorithm, aiming to effectively explore and exploit the search space. It divides the search space by multiple populations. The distribution of solutions in each population is kept in the associated memory. The multi-memory multi-population approach is to capture dynamic changes and maintain search diversity. The memetic component, which is a hybrid Genetic Algorithm (GA) and local search, is to nd high quality solutions. The performance of the proposed algorithm is evaluated on benchmark DSPR instances under both cyclic and acyclic environments. Our method obtained better results when compared with existing methods in the literatures, showing the effectiveness of the proposed algorithm in handling dynamic optimisation. Keywords: dynamic shortest path routing; memetic algorithms; dynamic optimisatio; evolutionary algorithm 112 PRICAI/PRIMA/PKAW 2016 Program Book A Novel Isolation-Based Outlier Detection Method Yanhui Shen, Huawen Liu, Yanxia Wang*, Zhongyu Chen, Guanghua Sun Department of Computer Science, Zhejiang Normal University, Jinhua, 321004, China [email protected] Abstract. Outlier detection is one of the most important tasks in data analysis. It refers to the process of recognizing unusual characteristics which may provide useful insights in helping us to understand the behaviors of data. In the pa-per, an isolation-based outlier detection method, called Entropy-based Greedy Isolation Tree (EGiTree), is proposed. Unlike other tree-like detection methods, our method exploits a half-baked isolation tree, which is constructed via three entropy-based heuristics, to identify outliers. Specifically, the heuristics are used to guide the selection process of attribute and its split value when constructing the tree. Thus, the outlierness score of each data point is estimated based on the total partition cost of the isolation node in the tree, as well as the path length and complexity of partition. Experiment results on public real-world datasets show that our approach outperforms distanced-based, density-based, subspace-based as well as state of-the-art isolation-based approaches.

When the multi-UAVs cooperatively attack multi-tasks, the dynamic changes of environments can lead to a failure of the tasks. So a novel path re-planning algorithm of multiple Q-learning based on cooperative fuzzy C means clustering is proposed. Our approach first reflects the dynamic changes of re-planning space by updating the fuzzy cooperative matrix. Then, the key way-points on the current global paths are used as the initial clustering centers for the cooperative fuzzy C means clustering, which generates the classifications of space points for multitasks. Furthermore, we use the classifications as the state space of each task and the fuzzy cooperative matrix as the reward function of the Q-learning. So a multi Q-learning algorithm is presented to synchronously re-plan the paths for multi-UAVs at every step. The simulation results show that the method subtracts the re-planning space of the tasks and improves the search efficiency of the learning algorithm, Keywords: Multi-UAVs; cooperative fuzzy C means clustering; multi Q-learning; path re-planning. 114 PRICAI/PRIMA/PKAW 2016 Program Book A Relaxed K-SVD Algorithm for Spontaneous Micro-Expression Recognition Hao Zheng123 Xin Geng2;Zhongxue Yang1 1Key Laboratory of Trusted Cloud Computing and Big Data Analysis, School of Information Engineering, Nanjing XiaoZhuang University, Nanjing, China 2MOE Key Laboratory of Computer Network and Information Integration, School of Computer Science and Engineering, Southeast University, Nanjing, China 3State Key Laboratory for Novel Software Technology, Nanjing University, Nanjing, China Abstract. Micro-expression recognition has been a challenging problem in computer vision due to its subtlety, which are often hard to be concealed. In the paper, a relaxed K-SVD algorithm (RK-SVD) to learn sparse dictionary for spontaneous micro-expression recognition is proposed. In RK-SVD, the reconstruction error and the classication error are considered, while the variance of sparse coefficients is minimized to address the similarity of same classes and the distinctiveness of dierent classes. The optimization is implemented by the K-SVD algorithm and stochastic gradient descent algorithm. Finally a single overcomplete dictionary and an optimal linear classier are learned simultaneously. Experimental results on two spontaneous micro-expression databases, namely CASME and CASME II, show that the performance of the new proposed algorithm is superior to other state-of-the-art algorithms.

Much of the experience of videogame players remains hidden. This paper presents an empirical study that assesses the experience of 50 participants (i.e. 25 children and 25 adults) during brain games play. Results from the empirical study show a number of significant correlations among diverse kinds of players’ experiences (i.e. engagement, enjoyment, anxiety, usability, adaptability and noninvasiveness). It is further identified by the study that the similarities and differences exist among the experiences of children and adults. Consequently, the observations of presenting study provide an insight against the experience of players during brain games play, which was previously unknown. Besides, we exploit these insights to successfully narrow down the complexity of user feedback process for brain games playing activity.

We present a system to acquire knowledge on the activities of people engaged in certain occupations. While most of the previous studies acquire phrases related to the occupation, our system acquires pairs of a verb and one of its arguments, which we call activities. Our system acquires activities from sentences written by people engaged in the target occupations as well as from sentences whose subjects are the target occupations. Through experiments, we show that the activities collected from each resource have dierent characteristics and the system based on the two resources would perform robustly for various occupations.

This paper investigates how norm emergence can be facilitated by agents’ adaptive learning behaviors in networked multiagent systems. A general learning framework is proposed, in which agents candynamically adapt their learning behaviors through social learning of their individual learning experience.

In this paper, by combining both, we propose a software architecture named ALLIANCE-ROS for developing fault-tolerant cooperativemulti-robot systems with a lot of software resources available.We encapsulate the ROS mechanisms and Python libraries to construct the basic function units of the ALLIANCE model. One may inherit them to construct the ALLIANCE-modelapplication with all ROS algorithms, modules and resources available. This work is demonstrated by an experiment of multi-robot patrol in both the simulated and the real environments. Keywords: multi-robot, fault-tolerant, cooperative, ALLIANCE-ROS 118 PRICAI/PRIMA/PKAW 2016 Program Book An Analysis of Influential Users for Predicting the Popularity of News Tweets Krissada Maleewong School of Information Technology, Shinawatra University, Pathumthani, Thailand [email protected] Abstract. Twitter plays an important role in today social network. Its key mechanism is retweet that disseminates information to broad audiences within a very short time and help increases the popularity of the social content. Therefore, an effective model for predicting the popularity of tweets is required in various domains such as news propagation, viral marketing, personalized message recommendation, and trend analysis. Although many studies have been extensively researched on predicting the popularity of tweets, they mainly focus on the content-based and the author-based features, while retweeter-based features are less concerned. This paper aims to study the impact of influential users who retweet tweets, also called retweeters, and presents simple yet effective measures for predicting the influence of retweeters on the popularity of online news tweets. By analyzing the popularity of news tweets and the impact of the retweeters, a number of useful measures are defined to evaluate influence of users in the retweeter network, and used to establish the prediction model. The experimental results show that the application of the retweeter-based features is highly effective and enhances the performance of the prediction model with high accuracy. Keywords: Twitter, Retweet, Influential User, Active User, Popular User, News Tweet, Social Network 119 PRICAI/PRIMA/PKAW 2016 Program Book An Empirical Local Search for the Stable Marriage Problem Hoang Huu Viet1, Le Hong Trang1, SeungGwan Lee2, and TaeChoong Chung3 1Department of Information Technology, Vinh University, 182-Le Duan, Vinh City, Nghe An, VietNam ([email protected](B), [email protected]) 2Humanitas College, Kyung Hee University 3Department of Computer Engineering, Kyung Hee University, 1732, Deogyeong-daero, Giheung-gu, Yongin-si, Gyeonggi-do, 446-701, Korea ([email protected], [email protected]) Abstract. This paper proposes a local search algorithm to find the egalitarian and the sex-equal stable matchings in the stable marriage problem. Based on the dominance relation of stable matchings from the men’s point of view, our approach discovers the egalitarian and the sex-equal stable matchings from the man-optimal stable matching. By employing a breakmarriage strategy to find stable neighbor matchings of the current stable matching and moving to the best neighbor matching, our local search nds the solutions while moving towards the woman-optimal stable matching. Simulations show that our proposed algorithm is efficient for the stable marriage problem. 120 PRICAI/PRIMA/PKAW 2016 Program Book An FAQ Search Method Using a Document Classifier Trained with Automatically Generated Training Data Takuya Makino, Tomoya Noro, and Tomoya Iwakura Fujitsu Laboratories Ltd. {makino.takuya, t.noro iwakura.tomoya}@jp.fujitsu.com Abstract. We propose an FAQ (Frequently Asked Question) search method that uses classification results of input queries. FAQs aim at covering frequently asked topics and users usually search topics in FAQs with queries represented by bag-of-words or natural language sentences. However, there is a problem that each question in FAQs is not usually sufficient enough to cover variety of queries that have the similar meaning but different surface expressions, such as synonyms, paraphrase and causal relations due to each topic usually consists of a representative question and its answer. As a result, users who cannot find their answers in FAQs ask a call center operator. To consider similarity of meaning among different surface expressions, we use a document classier that classifies each query into topics of FAQs. A document classifier is trained with not only FAQs but also corresponding histories of operators for covering variety of queries. However, corresponding histories do not include links to FAQs, we use a method for generating training data from the corresponding histories with FAQs. To generate training data correctly, the method takes advantage of a characteristic that many answers in corresponding histories related to FAQs are created by quoting corresponding FAQs. Our method uses a surface similarity between answers in corresponding histories and the answer part of each topic in FAQs for automatically generating training data. Experimental results show that our method outperforms an FAQ search based method using word matching in terms of Mean Reciprocal Rank and Precision@N. 121 PRICAI/PRIMA/PKAW 2016 Program Book An Investigation of Objective Interestingness Measures for Association Rule Mining Ratchasak Somyanonthanakul1 and Thanaruk Theeramunkong2 1Department of Medical Informatics, College of Information and Communication Technology, Rangsit University, Thailand [email protected] 2Sirindhorn International Institute of Technology, Thammasat University, Thailand [email protected] Abstract. While a large number of objective interestingness measures have been proposed to describe an association pattern which encodes meaningful relationship among attributes in a dataset, their characteristics and interrelations are not well explored. In this work, we investigate static and dynamic characteristics of 21 commonly used interestingness measures in order to understand their common and distinct properties. Four systematical methods investigated are (1) trend analysis, (2) fixed-total variable-portion analysis, (3) fixed-total fixed-portion-combination analysis, and (4) imbalance and extreme scenario analysis. A correlation analysis has been made to find interrelation patterns of the measures. Keywords: Association rules, interestingness, measure analysis. 122 PRICAI/PRIMA/PKAW 2016 Program Book An Orientation Histogram based Approach for Fall Detection using Wearable Sensors Nguyen Ngoc Diep, Cuong Pham, and Tu Minh Phuong Computer Science Department, Posts and Telecommunications Institute of Technology, Vietnam Machine Learning & Applications Lab, Posts and Telecommunications Institute of Technology, Vietnam {diepnguyenngoc,cuongpv,phuongtm}@ptit.edu.vn Abstract. Histogram features are extracted by calculating the distribution of orientations of small fragments or quanta of sliding windows on the sensors continuously acceleration data stream. Bins of the histogram is automatically computed based on clusters of similar orientations of quanta, making it less sensitive to parameters used in selection of bins than a heuristic approach. We also present a ner representation of the sliding window by applying the above extraction method to extract local feature vectors of small data segments instead of calculating features from the whole sliding window. Extracted features are used with support vector machines trained to classify frames of data streams into contain- ing falls or non-falls. We evaluated the proposed method on three public datasets with acceleration data including falls and other activities of daily living. On all three datasets, performance of the proposed method is substantially higher than two other fall detection methods.

We proposed an automated method for distinguishing cytokines from other proteins according to their primary sequences. Two strategies were employed to extract features from protein sequences. The first one is a single method, which includes autocorrelation and pseudo amino acid composition extracted feature methods based on composition and physical–chemical properties of proteins; while the second one is an optimal dimension searching method. Moreover, we developed BDSCyto as a web server to help researchers in classifying protein sequences efficiently and accurately. BDSCyto reduces the processing time and offers high accuracy by a series of efficient methods and multithreading technology based on Spark for largescale data. Currently, numerous methods exceed 90% accuracy in cytokine protein prediction, which is better than the existing single methods. BDSCyto is an opensource project and can be freely accessed by the public at http://bdscyto.sinaapp.com/. 124 PRICAI/PRIMA/PKAW 2016 Program Book Capability-aware Trust Evaluation Model in Multi-agent Systems Tung Doan Nguyen, Quan Bai, and Weihua Li School of Engineering, Computer and Mathematical Sciences, Auckland University of Technology, New Zealand, {tung.nguyen, quan.bai, weihua.li}@aut.ac.nz Abstract. Modeling trust in a real time of dynamic multi-agent systems is important but challenging, particularly when agents frequently join and leave, and the structure of the society may often change. With the increasing complexity of services, some simplied assumptions, e.g., unlimited processing capability, adopted by several trust models have shown their limitations which restrict the application of trust model in real-world situations. This paper attempts to relax the unlimited processing capability assumption of agents by introducing a capability-aware trust evaluation with temporal factor using hidden Markov model. The experimental results show that the approach not only can improve the accuracy of trust computation but also benet the trust-aware decision making for both individual and agent group context. Keywords: multi-agent system, trust, composite services, capability-aware 125 PRICAI/PRIMA/PKAW 2016 Program Book Combining RDR-based Machine Learning Approach and Human Expert Knowledge for Phishing Prediction Hyunsuk Chung, Renjie Chen, Soyeon Caren Han, and Byeong Ho Kang School of Engineering and ICT, Tasmania 7005, Australia {David.Chung, renjiec, Soyeon.Han, Byeong.Kang}@utas.edu.au Abstract. Detecting phishing websites has been noted as complex and dynamic problem area because of the subjective considerations and ambiguities of detection mechanism. We propose a novel approach that uses Ripple-down Rule (RDR) to acquire knowledge from human experts with the modified RDR model-generating algorithm (Induct RDR), which applies machine-learning approach. The modified algorithm considers two different data types (numeric and nominal) and also applies information theory from decision tree learning algorithms.Our experimental results showed the proposing approach can help to deduct the cost of solving over-generalization and over-fitting problems of machine learning approach. Three models were included in comparison: RDR with machine learning and human knowledge, RDR machine learning only and J48 machine learning only. The result shows the improvements in prediction accuracy of the knowledge acquired by machine learning.

Maximum Margin Matrix Factorization is one of the very popular techniques of collaborative ltering. The discrete valued rating matrix with a small portion of known ratings is factorized into two latent factors and the unknown ratings are estimated by the resulting product of the factors. The factorization is achieved by optimizing a loss function and the optimization is carried out by gradient descent or its variants. It is observed that any of these algorithms yields near-global optimizing point irrespective of the initial seed point. In this paper, we propose to combine swarm-like search with gradient descent search. Our algorithm starts from multiple initial points and uses gradient information and swarm-search as the search progresses. We show that by this process we get an efficient search scheme to get near optimal point for maximum margin matrix factorization. Computing Probabilistic Assumption-based Argumentation Nguyen Duy Hung Sirindhorn International Institute of Technology, Thailand [email protected] Abstract. We develop inference procedures for a recently proposed model of probabilistic argumentation called PABA, taking advantages of well-established dialectical proof procedures for Assumption-based Argumentation and Bayesian Network algorithms. We establish the soundness and termination of our inference procedures for a general class of PABA frameworks. We also discuss how to translate other models of probabilistic argumentation into this class of PABA frameworks so that our inference procedures can be used for these models as well.

We address the problem of efficiently detecting critical links in a large network. Critical links are such links that their deletion exerts substantial effects on the network performance. Here in this paper, we define the performance as being the average node reachability. This problem is computationally very expensive because the number of links is an order of magnitude larger even for a sparse network. We tackle this problem by using bottom-k sketch algorithm and further by employing two new acceleration techniques: marginal-link updating (MLU) and redundant-link skipping (RLS). We tested the effectiveness of the proposed method using two real-world large networks and two synthetic large networks and showed that the new method can compute the performance degradation by link removal about an order of magnitude faster than the baseline method in which bottom-k sketch algorithm is applied directly. Further, we confirmed that the measures easily composed by well known existing centralities, e.g. in/out-degree, betweenness, PageRank, authority/hub, are not able to detect critical links. Those links detected by these measures do not reduce the average reachability at all, i.e. not critical at all. Keywords: Social networks, Link deletion, Critical links, Node reachability 128 PRICAI/PRIMA/PKAW 2016 Program Book Distributed B-SDLM: Accelerating the Training Convergence of Deep Neural Networks through Parallelism Shan Sung Liew1, Mohamed Khalil-Hani1, and Rabia Bakhteri2 1VeCAD Research Laboratory Faculty of Electrical Engineering Universiti Teknologi Malaysia 81310 Skudai, Johor Malaysia 2Machine Learning Developer Group Sightline Innovation #202, 435 Ellice Ave Winnipeg MB R3B 1Y6 Canada [email protected], [email protected], [email protected] Abstract. This paper proposes an efficient asynchronous stochastic second order learning algorithm for distributed learning of neural networks (NNs). The proposed algorithm, named distributed bounded stochastic diagonal Levenberg-Marquardt (distributed B-SDLM), is based on the BSDLM algorithm that converges fast and requires only minimal computational overhead than the stochastic gradient descent (SGD) method. The proposed algorithm is implemented based on the parameter server thread model in the MPICH implementation. Experiments on the MNIST dataset have shown that training using the distributed B-SDLM on a 16-core CPU cluster allows the convolutional neural network (CNN) model to reach the convergence state very fast, with speedups of 6:03 and 12:28 to reach 0:01 training and 0:08 testing loss values, respectively. This also results in significantly less time taken to reach a certain classification accuracy (5:67 and 8:72 faster to reach 99% training and 98% testing accuracies on the MNIST dataset, respectively). Keywords: Deep learning, distributed machine learning, stochastic diagonal Levenberg-Marquardt, convolutional neural network. 129 PRICAI/PRIMA/PKAW 2016 Program Book Early Detection of Osteoarthritis Using Local Binary Patterns: A Study Directed at Human Joint Imagery Kwankamon Dittakan1 and Frans Coenen2 1Faculty of Technology and Environment, Prince of Songkla University, Phuket Campus, 80 Moo 1, Vichit-Songkram Road, Kathu, Phuket, Thailand 2Department of Computer Science, University of Liverpool, Liverpool, L69 3BX, United Kingdom {[email protected],[email protected]} Abstract. Osteoarthritis (OA) is a chronic health condition that causes severe joint pain and stiffness; it is a major cause of disability in older people. The risk of OA increases from age 45 and older. Early diagnosis is typically made using X-ray imagery. In this paper an automated mechanism for OA screening is proposed. The fundamental idea is to generate a classifier that is able to distinguish between OA or non-OA images. The challenge is how bast to translate an X-ray image into a form that serves to both captures key information while remaining compatible with the classification process. It is suggested that image texture is the most desirable feature to be considered. The process is filly described and evaluated. The data used for the evaluation was obtained from the right Tibia of 50 female subjects. Excellent results were obtained, recorded AUC values of 1:0.

Parking Deposit System (PDS) is proposed to improve public acceptance of road pricing (RP), which can reduce effectively traffic congestion and air pollution. This study examines the characteristics of PDS and conventional cordon-based RP in terms of efficiency and equity. In order to evaluate income regressive effects as equity, we develop a multi-agent based simulator which can consider user’s mode and route choice behaviors for several income classes. The results of empirical analysis at the Nagoya Metropolitan Area suggest the followings in comparison with conventional RP: 1) PDS gives sufficient environmental improvement by reducing car use, although the effect of decreases by refund, and 2) PDS is more equitable because it is a kind of revenue allocation scheme. Keywords: Traffic problem, Road pricing, Agent based simulation Exploring Multi-Action Relationship in Reinforcement Learning Han Wang and Yang Yu* National Key Laboratory for Novel Software Technology, Nanjing University, Nanjing 210023, China {wangh,yuy}@lamda.nju.edu.cn Abstract. In many real-world reinforcement learning problems, an agent needs to control multiple actions simultaneously. To learn under this circumstance, previously, each action was commonly treated independently with other. However, these multiple actions are rarely independent in applications, and it could be helpful to accelerate the learning if the underlying relationship among the actions is utilized. This paper explores multi-action relationship in reinforcement learning. We propose to learn the multi-action relationship by enforcing a regularization term capturing the relationship. We incorporate the regularization term into the least-square policy-iteration and the temporal-difference methods, which result efficiently solvable convex learning objectives. The proposed methods are validated empirically in several domains. Experiment results show that incorporating multi-action relationship can effectively improve the learning performance. 131 PRICAI/PRIMA/PKAW 2016 Program Book Face Verication Algorithm with Exploiting Feature Distribution Zhi Qu, Xuan Li, Yong Dou*, and Ke Yang. Key Laboratory of Parallel Distribution National University of Defense Technology SanYi avenue, Changsha, Hunan province, China [email protected] Abstract. Deep feature is widely applied in many elds such as image retrieval, image classication, face verication, etc. All the post-processing methods using deep feature make some assumptions about feature distribution. However, in most situations, features do not follow the hypothesised distribution approximately. In this paper, we focus on face-verication applications which also suer from these problems. We propose an up-sample method called IUSM to alleviate the problems caused by biased samples. Additionally, by analyzing the Joint Bayesian model theoretically and practically, we propose a feature fusion method called LFF which utilizes the distribution properties of Joint Bayesian. Based on IUSM, the face verication accuracy of biased data is improved by 6% while generalization ability of convolution network is not crippled. On the widely used Labeled Face in the Wild(LFW) dataset, LFF method can slightly improve the accuracy 0.15% while the baseline accuracy is more than 97.51%. We also argue that LFF can improve each deep face verication algorithm which uses Joint Bayesian model due to LFF’s linear combination of features. 132 PRICAI/PRIMA/PKAW 2016 Program Book Facial Age Estimation by Total Ordering Preserving Projection Xiao-Dong Wang and Zhi-Hua Zhou National Key Laboratory for Novel Software Technology Nanjing University, Nanjing 210023, China {wangxd,zhouzh}@lamda.nju.edu.cn Abstract. Facial age estimation is one of the unsolved challenging issues in automatic face perception. Previous studies usually formulated it as a classication problem, where each age is regarded as a class, or a regression problem where the age is regarded as a variable spanning in a real-valued interval. In this paper, we propose to formulate this task as an ordinal regression problem. On one hand, the new formulation emphasizes the fact that the age estimation problem is inherently a classication problem (ordinal regression is a special kind of classication task); on the other hand, the new formulation allows to take into account the order information between dierent ages, which has been ignored by previous classication formulation. We develop the TOPP (Total Ordering Preserving Projection) approach, by identifying the low-dimensional subspace which preserves the ordinal relations to the best, and experiments show that TOPP signicantly outperforms state-of-the-art age estimation methods. Keywords: ordering preserving projection, ordinal regression, facial ageestimation, face perception, machine learning 133 PRICAI/PRIMA/PKAW 2016 Program Book Fast Training of a Graph Boosting for Large-Scale Text Classication Hiyori Yoshikawa and Tomoya Iwakura Fujitsu Laboratories Ltd., Kawasaki, Japan {y.hiyori,iwakura.tomoya}@jp.fujitsu.com Abstract. This paper proposes a fast training method for graph classication based on a boosting algorithm and its application to sentimental analysis with input texts represented by graphs. Graph format is very suitable for representing texts structured with Natural Language Processing techniques such as morphological analysis, Named Entity Recognition, and parsing. A number of classication methods which represent texts as graphs have been proposed so far. However, many of them limit candidate features in advance because of quite large size of feature space. Instead of limiting search space in advance, we propose two approximation methods for learning of graph-based rules in a boosting. Experimental results on a sentimental analysis dataset show that our method contributes to improved training speed. In addition, the graph representation-based classication method exploits rich structural information of texts, which is impossible to be detected when using other simpler input formats, and shows higher accuracy. Keywords: text classication feature engineering graph boosting Faster Convergence to Cooperative Policy by Autonomous Detection of Interference States in Multiagent Reinforcement Learning Sachiyo Arai and Haichi Xu Faculty of Engineering, Chiba University, 1-33 Yayoi-cho, Inage-ku, Chiba 263-8522, JAPAN Abstract. In this paper, we propose a method for ameliorating the state-space explosion that can occur in the context of multiagent reinforcement learning. In our method, an agent considers other agents’ states only when they interfere with each other in attaining their goals. Our idea is that the initial state-space of each agent does not include information about other spaces. Agents then automatically expand their state-space if they detect interference states. We adopt the information theory measure of entropy to detect the interference states for which agents should consider the state information of other agents. We demonstrate the advantage of our method with respect to the efficiency of global convergence.

Noise removal in image restoration is an important technique of image processing. In this paper, a new efficient approach is proposed for removing the mixed Gaussian-impulse noise in a color image. The proposed method utilizes the concept of local rank ordered absolute distances to measure similarity between a processing pixel in the small window and their neighborhood pixels in the processing block. The generalized extreme value distribution was employed to estimate weighted averages of the pixels in the processing block for filtering the mixed Gaussian-impulse noise. From the experimental results, our filter has yielded the better results in suppressing high density levels of the mixed noise in the color images than the state-of-the-art denoising methods. Keywords: generalized extreme value; mixed Gaussian-impulse noise; local rank ordered absolute distances. Generating Covering Arrays with pseudo-Boolean Constraint Solving and Balancing Heuristic* Hai Liu2, Feifei Ma1, Jian Zhang1 1State Key Laboratory of Computer Science Institute of Software, Chinese Academy of Sciences Email: fma,[email protected] 2Beijing Information Science and Technology University Email: [email protected] Abstract. Covering arrays (CAs) are interesting objects in combinatorics and they also play an important role in software testing. It is a challenging task to generate small CAs automatically and efficiently. In this paper, we propose a new approach which generates a CA column by column. A kind of balancing heuristic is adopted to guide the searching procedure. At each step (column extension), some pseudo Boolean constraints are generated and solved by a PBO solver. A prototype tool is implemented, which turns out to be able to nd smaller CAs than other tools, for some cases. 135 PRICAI/PRIMA/PKAW 2016 Program Book Grouped Text Clustering Using Non-Parametric Gaussian Mixture Experts Yong Tian, Yu Rong, Yuan Yao, Weidong Liu, and Jiaxing Song Department of Computer Science and Technology, Tsinghua University, Beijing, China [email protected], [email protected], [email protected], [email protected], [email protected] Abstract. Text clustering has many applications in various areas. Before being clustered, texts often have already been grouped or partially grouped in practise. Texts from the same group are related to each other and concentrate on a few topics. The group information turns out to be valuable for text clustering. In this paper, we propose a model called Non-parametric Gaussian Mixture Experts to get better clustering result through utilizing group information. After converting texts to vectors by semantic embedding, our model can automatically infer proper cluster number for every group and the whole corpus. We develop an online variational inference algorithm which is scalable and can handle incremental datasets. Our algorithm is tested on various text datasets. The results demonstrate our model has signicantly better performance in cluster quality than some other classical and recent text clustering methods. Hybrid Temporal-Dierence Algorithm using Sliding Mode Control and Sigmoid Function Ke Xu and Fengge Wu Science and Technology on Integrated Information System Laboratory Institute of Software Chinese Academy of Sciences {xuke13,fengge}@iscas.ac.cn Abstract. Gradient temporal-dierent algorithms such as GTD2 and TDC have improved the accuracy of the algorithm to a new level. Unfortunately, these algorithms converge much slower than conventional temporal-dierent algorithms. In this paper, we present a approach based on sliding mode control to speed up the GTD2 algorithm, and then use sigmoid function to reduce algorithm’s jitter. Our experiments on random walk show that our algorithm converges as fast as conventional temporal-dierent algorithms and as accurate as GTD2 algorithm at the same time. This is an important property for online-learning tasks.

In Twitter, the sentiments of individual tweets are dicult to classify, but the overall opinion of a user can be determined by considering their related tweets and their social relations. It would be better to consider not only the textual information in the tweets, but also the relationships between the users. Previous approaches that incorporate network information into the classier have mainly focussed on \a link” dened by the explicitly connected network, such as, follow, mention, or retweet. However, the presence of explicit link structures in some social networks is limited. In this paper, we propose a framework that takes into consideration the \ implicit connections” between users. An implicit connection refers to the relations of users who share similar topics of interest, as extracted from their historical tweet corpus, which contains much data for analysis. The results of experiments show that our method is effective and improves the performance compared to the baselines.

Given the steady increase of published and stored information in the form of Arabic unstructured texts, current Information Retrieval (IR) systems must be able to suit the nature and requirements of this language for an accurate and efficient search. This paper sheds light on the challenges in Arabic IR (AIR) and proposes an approach for enhancing the process of AIR based on transforming these texts into structured documents in XML format through a document ontology as well as a set of linguistic grammars. The IR system hence is done on the XML documents. The aim of such system is to incorporate the knowledge on the document structure and on specic content elements in computing the relevance of an information element. A query expansion module mainly based on domain ontology as well as user prole is proposed for the enhancement of the search results.

Graph-based semi-supervised learning (GSSL) is one of the most important semi-supervised learning (SSL) paradigms. Though GSSL methods are helpful in many situations, they may hurt performance when using unlabeled data. In this paper, we propose a new GSSL method GsslIs based on instance selection in order to reduce the chances of performance degeneration. Our basic idea is that given a set of unlabeled instances, it is not the best to exploit all the unlabeled instances; instead, we should exploit the unlabeled instances which are highly possible to help improve the performance, while do not take the ones with high risk into account. Experiments on a board range of data sets show that the chance of performance degeneration of our proposal is much smaller than that of many state-of-the-art GSSL methods.

Continuous Conditional Random Fields (CCRF) has been widely applied to various research domains as an efficient approach for structural regression. In previous studies, the weights of CCRF are constrained to be positive from a theoretical perspective. This paper extends the definition domains of weights of CCRF and thus introduces L1 norm to regularize CCRF, which enables CCRF to perform feature selection. We provide a plausible learning method for L1-Regularized CCRF (L1- CCRF) and verify its effectiveness. Moreover, we demonstrate that the proposed L1-CCRF performs well in selecting key features related to the various customers’ power usages in Smart Grid.

Traditional face recognition algorithms can achieve significant performance under well-controlled environments. However, these algorithms perform poorly when the resolution of the face images varies. A two-step framework is proposed to solve the resolution problem through adopting super-resolution (SR) and performing face recognition on the super-resolved face images. However, such method usually has poor performance on recognition tasks as SR focuses more on visual enhancement, rather than classification accuracy. Recently, Coupled Mapping (CM) has been introduced into face recognition framework across different resolutions, which learns a common feature subspace for both high-resolution (HR) and low-resolution (LR) face images. In this paper, inspired by maximum margin projection, we propose Large Margin Coupled Mapping (LMCM) algorithm, which learns projections to maximize the margin between distance of between-class subjects and distance of within-class ones in the common space. Experiments on public FERET and SCface databases demonstrate that LMCM is effective for low-resolution face recognition.

We present an attempt to use a large amount of summaries contained in the New York Times Annotated Corpus (NYTAC). We introduce five methods inspired by domain adaptation techniques in other research areas to train our supervised summarization system and evaluate them on three test sets. Among the five methods, the one that is trained on the NYTAC followed by fine-tuning on the target data (i.e. the three test sets; DUC2002, RSTDTBlong and RSTDTBshort) performs the best for all the test sets. We also propose an instance selection method according to the faithfulness of the extractive oracle summary to the reference summary and empirically show that it improves summarization performance. Learning of Evaluation Functions to Realize Playing Styles in Shogi Shotaro Omori* and Tomoyuki Kaneko Graduate School of Arts and Sciences, the University of Tokyo, {omori,kaneko}@graco.c.u-tokyo.ac.jp Abstract. This paper presents a method to give a computer player an intended playing style by the machine learning of an evaluation function. Recent improvements in machine learning techniques have realized the automated tuning of the feature weight vector of an evaluation function. To make a strong player, as many moves as possible of strong players’ game records are needed, though the number of available game records decreases when we focus on a specic playing style. To pursue both goals of playing style and playing strength, we present three steps of learning: classifying moves with respect to playing styles, training the weight vector of an evaluation function by using the whole set of game records to maximize its playing strength, and modifying the weight vector carefully so as to improve agreement with the moves of the intended playing style. We applied our method to realize players of defense or attack-oriented style in shogi and tested the players by self-play against the original version. The results conrmed that the presented method successfully adjusted evaluation functions in that the frequency of defensive moves is signicantly increased or decreased in accordance with the game records used while keeping the winning ratio at almost 50%. 142 PRICAI/PRIMA/PKAW 2016 Program Book Learning Sentimental Weights of Mixed-gram Terms for Classication and Visualization Tszhang Guo12 Bowen Li1, Zihao Fu3, Tao Wan14, and Zengchang Qin1 1Intelligent Computing and Machine Learning Lab, School of ASEE, Beihang University, Beijing, 100191, China 2Department of Automation, Tsinghua University, Beijing, China 3Alibaba Group, Beijing, 100022, China 4School of Biological Science and Medical Engineering, Beihang University [email protected],[email protected] {tao.wan.wan,libowen.ne,zengchang.qin}@gmail.com Abstract. Sentimental analysis is an important topic in natural language processing and opinion mining. Many previous studies have reported to judge whether a term is with emotion or not. However, little work has been done in measuring degrees of sentiment for these terms. For example, the word excellent has stronger positive sentiment than the word good and okay. In this paper, we investigate how to model this intricate sentimental difference by assigning sentimental weights. A simple and effective model is proposed based on logistic regression to extract emotional terms associated with sentiment weights. Weighted terms can be used in sentiment classification and visualization by drawing emotional clouds of texts. The new model is tested using uni-gram, bi-gram and mixedgram language models on two benchmark datasets. The empirical results show that the new model is highly efficient with comparable accuracy to other sentiment classifiers. Learning with Additional Distributions Sanparith Marukatat IMG lab, NECTEC 112 Thailand Science Park, Pathumthani, Thailand [email protected] Abstract. This paper studies the problem of learning with distributions. In this work, we do not focus on the distribution that represents each data point. Instead, we consider the distribution that is an additional information around each data point. The proposed method yields a new kernel that is similar to an existing one. The main dierence is that our kernel requires an integration in the kernel space. Theoretically, the proposed method yields a better generalization compared to normal SVM.

Finding minimum vertex covers (MinVC) for simple undirected graphs is a well-known NP-hard problem. In the literature there have been many heuristics for obtaining good vertex covers. However, most of them focus on solving this problem in relatively small graphs. Recently, a local search solver called FastVC is designed to solve the MinVC problem on real-world massive graphs. Since the traditional best- picking heuristic was believed to be of high complexity, FastVC replaces it with an approximate best-picking strategy. However, since best-picking has been proved to be powerful for a wide range of problems, abandoning it may be a great sacrice. In this paper we have developed a local search MinVC solver which utilizes best-picking with noise to remove vertices. Experiments conducted on a broad range of real-world massive graphs show that our proposed method finds better vertex covers than state-of-the-art local search algorithms on many graphs.

China {faaronzheng,hxue}@seu.edu.cn,[email protected],[email protected] Abstract. Encoding is one of the most important steps in Error Correcting Output Codes (ECOCs). Traditional encoding strategies are usually data-independent. Recently, some tree-form encoding algorithms are proposed which rstly utilize mutual information to estimate inter-class separability in order to create a hierarchical partition of the tree from top to down and then obtain a coding matrix. But such criterion is usually computed by a non-parametric method which would generally require vast samples and is more likely to lead to unstable results. In this paper, we present a novel encoding algorithm which uses the maximum margins between classes as the criterion and constructs a bottom-up binary tree based on the maximum margin. As a result, the corresponding coding matrix is more stable and discriminative for the following classication. Experimental results have shown that our algorithm performs much better than some state-of-the-art coding algorithms in ECOC.

We attempt stochastic modeling of travel behavior processes from the observed data. To this end, based on the Le´vy flight behavior process combined with the popularity of each point of interest, we first propose a probability model and efficient method that estimates the model parameters from the observed user behavior data. Then, we propose two methods for POI ranking by using the probability obtained from our proposed model. In our experiments using user behavior data constructed from a review site dataset, we report our experimental results on parameter estimation and examine the properties of POI ranking methods in comparison to a naive popularity ranking method. As our experimental results, we show that our parameter estimation results are intuitively interpretable, and as a favorable property, our ranking methods naturally give high ranks to POIs located in attractive regions.

Human activity recognition is important in many applications such as fitness logging, pervasive healthcare, near-emergency warn ing, and social networking. Using body-worn sensors, these applications detect activities of the users to understand the context and provide them appropriate assistance. For accurate recognition, it is crucial to design appropriate feature representation of sensor data. In this paper, we propose a new type of motion features: motion primitive forests, which are randomized ensembles of decision trees that act on original l cal features by clustering them to form motion primitives (or words). The bags of these features, which accumulate histograms of the resulting motion primitives over each data frame, are then used to build activity models. We experimentally validated the effectiveness of the proposed method on accelerometer data on three benchmark datasets. On all three datasets, the proposed motion primitive orests provided substantially higher accuracy than existing state-of-the-art methods, and were much faster in both training and prediction, compared with k-means feature learning.In addition, the method showed stable results over different types of original local features, indicating the ability of random forests in selecting relevant local features.

R. China, 410073 [email protected] Abstract. Mapping 3D environments is a fundamental yet challenging problem for mobile robot applications. Although 3D sensory data can be effciently obtained using low-cost commercial RGB-D cameras, direct extension of the widely-adopted occ pancy grids to 3D environments would cause problems, such as large storage co sumption and intensive computation cost. In this paper, we propose to use a stack of 2D occupancy grids, each of which corresponds to a horizontal slice of the 3D environment at a specic height, as an efficient representation of 3D environments for indoor applications. Moreover, an existing algorithm based on Rao-Blackwellized Particle Filters (RBPF) is modied accordingly to perform simultaneous localization and mapping (SLAM) using the proposed multi-level occupancy grids (M-LOG), the entire codes of which have been made open source at https://github.com/AngelTianYu/ micros_mlog. Experimental results from both simulation and real-world tests validate the effectiveness of the proposed approach in indoor environments. Computational cost of the approach scales linearly with the number of 2D map slices, making it the user’s choice the trade-off between vertical map resolution and efficiency.

Most existing active learning methods often manually label samples and train models with labeled data in an iterative way. Unfortunately, at the early stage of the experiment, few labeled data are available, hence, selecting the most valuable data points to label is necessary and important. To this end, we propose a novel method, called Multiview Representative and Informative-induced Active Learning (MRI-AL), which selects samples of both representativness and informativeness with the help of complementarity of multiple views. Specically, subspace reconstruction with structure sparsity technique is employed to ensure the selected samples to be representative, while the global similarity constraint guarantees the informativeness of the selected samples. The proposed method is solved efficiently by alternating direction method of multipliers (ADMM). We empirically show that our method outperforms existing early experimental design approaches.

Dailey Computer Science and Information Management Asian Institute of Technology Klong Luang, Pathumtani, Thailand [email protected],[email protected] http://www.cs.ait.ac.th/ Abstract. Writing and drawing are basic forms of human communication. Handwritten and hand-drawn documents are often used at initial stages of a project. For storage and later usage, handwritten documents are often converted into a digital format with a graphics program. Drawing with a computer in many cases requires skill and more time than less formal handwritten drawings. Even when people have experience in computer drawing and are familiar with the application, it takes time. Automatic conversion of images of hand-drawn diagrams into a digital graphic format file could save time in the design process. One of early critical tasks in handdrawn diagram interpretation is segmentation of the diagram into text and non-text components. In this paper, we compare two approaches for offline text and non-text segmentation of contours in an image. We describe the feature extraction and classication processes. Our methods obtain 82-86% accuracy. Future work will explore the application of these techniques in a complete diagram interpretation system.

The DLF family of description logics are fragments of first order logic with underlying signatures based on unary predicate symbols, called atomic concepts, and unary function symbols interpreted as total functions, called features. We show how computational properties relating to a key reasoning service for dialects of this family are preserved when (a) unary function symbols are now interpreted as partial functions, and when (b) a concept constructor is admitted that can characterize circumstances in which partial functions become total. 150 PRICAI/PRIMA/PKAW 2016 Program Book On the Gradient-Based Sequential Tuning of the Echo State Network Reservoir Parameters Sumeth Yuenyong School of Information Technology, Shinawatra University 99 Moo 10 Bang Toey, Sam Khok District, Pathum Thani 12160, Thailand Abstract. In this paper, the derivative of the input scaling and spectral radius parameters of Echo State Network reservoir are derived. This was achieved by re-writing the reservoir state update equation in terms of template matrices whose eigenvalues can be pre-calculated, so the two parameters appear in the state update equation in the form of simple multiplication which is dierentiable. After that the paper derives the derivatives and then discusses why direct application of these two derivatives in gradient descent to optimize reservoirs in a sequential manner would be ineffective due to the nature of the error surface and the problem of large eigenvalue spread on the reservoir state matrix. Finally it is suggested how to apply the derivatives obtained here for joint-optimizing the reservoir and readout at the same time. Optimization of Road Distribution for Traffic System Based on Vehicle’s Priority Wen Gu and Takayuki Ito Nagoya Institute of Technology, Gokiso-cho, Showa-ku, Nagoya City, Aichi Pref., Japan [email protected] [email protected] Abstract. Instead of making the traffic system work uently by focusing on each car’s way to choose their routes, in this paper, we proposed a way to make the vehicles avoid being involved into the traffic congestion by allocating the roads which are regarded as one kind of resources to the vehicles. In order to make the road allocation fair, we introduce the parameter to show each vehicle’s priority. We allocate the roads by regarding it as a linear programming problem and use linear programming to solve it. The experiment was done by using simulator SUMO and we testied that our proposal can make the vehicles avoid getting involved into traffic congestion and veried the usefulness of the vehicle’s priority.

[vineet,akp][email protected], himaworld [email protected] 2Grith University, Brisbane, Australia [email protected] Abstract. Recommender systems can be viewed as prediction systems where we can predict the ratings which represent users’ interest in the corresponding item. Typically, items having the highest predicted ratings will be recommended to the users. But users do not know how certain these predictions are. Therefore, it is important to associate a condence measure to the predictions which tells users how certain the system is in making the predictions. Many dierent approaches have been proposed to estimate confidence of predictions made by recommender systems. But none of them provide guarantee on the error rate of these predictions. Conformal Prediction is a framework that produces predictions with a guaranteed error rate. In this paper, we propose a conformal prediction algorithm with item-based collaborative ltering as the underlying algorithm which is a simple and widely used algorithm in commercial applications. We propose dierent nonconformity measures and empirically determine the best nonconformity measure.We empirically prove validity and efficiency of proposed algorithm. Experimental results demonstrate that the predictive performance of conformal prediction algorithm is very close to its underlying algorithm with little uncertainty along with the measures of confidence and credibility.

In answer set programming, an extended logic program may have no answer set, or only one trivial answer set. In this paper, we propose a new stable model semantics based on the restricted four-valued logic to overcome both inconsistences and incoherences in answer set programming. Our stable models coincide with classical answer sets when reasoning on consistent and coherent logic programs, and can be solved by transformation in existing ASP solvers. We also show the connection between our stable models and the extensions of default logic.

This paper describes a method of domain adaptation, which involves adapting a classier developed from source to target data. We automatically select the training data set that is suitable for the target data from the whole source data of multiple domains. This is unsupervised domain adaptation for Japanese word sense disambiguation (WSD). Experiments revealed that the accuracies of WSD improved when we automatically selected the training data set using two criteria, the degree of condence and the leave-oneout (LOO)-bound score, compared with when the classier was trained with all the data.

Image is one of the most important means to express users’ emotions on microblogging, like Sina Weibo. More and more people post only images on it, due to the fast and convenient nature of image. Tak- ing a post only using images on microblogging has been a new tendency. Most existing studies about sentiment analysis on microblogging focus on the text, or integrate image as an auxiliary information into text, so they are not applicable in this scenario. Although a few methods related to sentiment analysis for image have been proposed, most of them either ignore the semantic gap between low-level visual features and higher-level image sentiments, or require a lot of textual information in the phases of both training and inference. This paper proposes a new sentiment analysis method based on Simple Multiple Kernel Learning (SimpleMKL). Specically, textual information as a sort of sufficiently emotional source data, we can use it to promote the ability via SimpleMKL to classify images. And once we get the image classier, none of texts are needed when predicting other unlabelled images. Experimental results show that our proposed method can improve the performance signicantly on data we crawled and labelled from Sina Weibo. We find that our method not only outperforms some common methods, like SVM, Naive Bayes, KNN, Random Forest, Adaboost, etc., using the image features of colour, hog, texture, but also outperforms some state-of-the-art methods.

Sparse representation has been widely used in visual tracking and achieves superior tracking results. However, most sparse representation models represent the target candidate as a linear combination of target templates and need to solve a sparse optimization problem. In this paper, we propose a novel set to set visual tracking (SSVT) method. Under the particle lter framework, we consider both the target candidates and target templates as image sets, and model them as convex hulls. Then the distance between two image sets is minimized and the tracking result is the target candidate with the maximum coefficient. As the target candidates are modeled as one convex hull, SSVT utilizes the underlying relationship of the target candidates. Moreover, SSVT is very efficient in that it only needs to solve one quadratic optimization problem rather than sparse optimization problems. Both qualitative and quantitative analyses on several challenging image sequences show that the proposed SSVT algorithm outperforms the state-of-the-art trackers.

Gerding2 1School of Computer Science and Technology, Wuhan University of Technology, Wuhan, China, [email protected] 2School of Electronics and Computer Science, University of Southampton, Southampton, UK Abstract. In this paper, we analyse how double auction marketplaces set an effective pricing policy to determine the transaction prices for matched buyers and sellers. We analyse this problem by considering continuous privately known trader types. Furthermore, we consider two typical pricing policies: equilibrium k pricing policy and discriminatory k pricing policy. We firstly investigate how to determine the transaction prices to reach the maximal allocative efficiency in an isolated marketplace when the traders adopt BayesNash equilibrium bidding strategies. We find that when the marketplace adopts discriminatory k pricing policy, the maximal allocative efficiency is reached by setting k=0.41 or 0.59.We find that equilibrium k pricing policy provides higher allocative efficiency than discriminatory k pricing policy.We further discuss how different pricing policies can affect traders’ Bayes-Nash equilibrium bidding strategies. Furthermore, we extend the analysis to the setting with two marketplaces competing against each other to attract traders. We find that the marketplace using equilibrium k pricing policy is more likely to beat the marketplace using discriminatory k pricing policy, where all traders converge to the marketplace using equilibrium k pricing policy in Bayes-Nash equilibrium. Our analysis can provide meaningful insights for designing an effective pricing policy.

Image super resolution (SR) is an active research topic to obtain an high resolution (HR) image from the low resolution (LR) observation. Many results of existing methods may be corrupted by some artifacts. In this paper, we propose an SR reconstruction method for single image based on nonlocal sparse and low-rank regularization. We form a matrix for each patch with its vectorized similar patches to utilize the redundancy of similar patches in natural images. This matrix can be decomposed as the low rank component and sparse part, where the low rank component depictures the similarity and the sparse part depictures the ne dierences and outliers. The SR result is achieved by the iterative method and corroborated by experimental results, showing that our method outperforms other prevalent methods.

Stigmergy-based Influence Maximization in Social Networks Weihua Li1, Quan Bai1, Chang Jiang1, and Minjie Zhang2 1Auckland University of Technology, New Zealand, [email protected]; [email protected]; [email protected] 2University of Wollongong, Australia [email protected] Abstract. Influence maximization is an important research topic which has been extensively studied in various elds. In this paper, a stigmergy based approach has been proposed to tackle the influence maximization problem. We modelled the influence propagation process as ant’s crawling behaviours, and their communications rely on a kind of biological chemicals, i.e., pheromone. The amount of the pheromone allocation is concerning the factors of influence propagation in the social network. The model is capable of analysing influential relationships in a social network in decentralized manners and identifying the influential users more efficiently than traditional seed selection algorithms.

The ever growing amount of Semantic Web data has made it increasingly dicult to analyse the information required by the users. Association rule mining is one of the most useful techniques for discovering frequent patterns among RDF triples. In this context, some statistical methods strongly rely on the user intervention that is time-consuming and error-prone due to a large amount of data. In these studies, the rule quality factors (e.g. Support and Condence measures) consider only knowledge in the instance-level data. However, Semantic Web data contains knowledge in both instance-level and schema-level. In this paper, we introduce an approach called SWARM (Semantic Web Association Rule Mining) to automatically mine Semantic Association Rules from RDF data. We discuss how to utilize knowledge encode in the schema-level to enrich the semantics of rules. We also show that our approach is able to reveal common behavioral patterns associated with knowledge in the instance-level and schema-level. The proposed rule quality factors (Support and Condence) consider knowledge not only in the instance-level but also schema-level. Experiments performed on the DBpedia Dataset (3.8) demonstrate the usefulness of the proposed approach.

The segmentation-based approach for Optical Character Recognition (OCR) works by first segmenting a text line image into individual character images and then recognizing the characters. The approach relies heavily on the performance of the segmentation process and thus suffers from the problem of touching and broken characters. On the other hand, the unsegmented approach for OCR processes the text line image without segmenting the image into individual characters, and the approach is more suitable for languages such as Thai that contains a lot of touching characters in nature. This paper proposes an application of Long Short-Term Memory (LSTM), which is an unsegmented method, to Thai OCR. The paper also introduces a method called vertical com-ponent shifting to solve the problem of a large number of vertically occurring character combinations that occur in four-level writing system of Thai, and pose difficulty for standard LSTM networks. The experimental results demonstrate the better accuracy of our proposed method over standard LSTM networks and other commercial software for Thai OCR.

[email protected], {akpcs,vineetcs}@uohyd.ernet.in, {vikas,uusandeepsahu}@uohyd.ac.in Abstract. Skyline queries aim at nding a set of skyline objects from the given database. For categorical data, the notion of preferences is used to determine skyline objects. There are many real world applications where the preference can be uncertain. In such contexts, it is relevant to determine the probability that an object is a skyline object in a database with uncertain pairwise preferences. Skyline query is to determine a set of objects having skyline probability greater than a threshold. In this paper, we address this problem. To the best of our knowledge, there has not been any technique which handles this problem directly. There have been proposals to compute skyline probability of individual objects but applying these for skyline query is computationally expensive. In this paper, we propose a holistic algorithm that determines the set of skyline objects for a given threshold and a database of uncertain preferences. We establish the relationship between skyline probability and the probability of the union of events. We guide our search to prune objects which are unlikely to be skyline objects. We report extensive experimental analysis to justify the efficiency of our algorithm. 160 PRICAI/PRIMA/PKAW 2016 Program Book Topic Detection in Group Chat Based on Implicit Reply Xinyu Zhang, Ning Zheng, Jian Xu, and Ming Xu School of Computer Science and Technology, Hangzhou Dianzi University Hangzhou, China {132050125,nzheng,jian.xu,mxu}@hdu.edu.cn Abstract. Topic detection in group chat has become a promising research due to the widely usage of Instant Messaging (IM) systems. Previous works mainly focus on improving the text similarity between two related messages by utilizing dierent weighting factors. However, the text similarity of related texts is likely to be zero (or near zero) due to the characteristics of short text messages in group chat. To solve this problem, an innovative topic detection method based on implicit reply which indicates chat messages interact with each other is proposed in this paper. The comparative experiments results on the datasets gathered from QQ groups demonstrate the superiority of the proposed method as compared to the baseline approaches.

This paper presents work-in-progress towards a computational approach for capturing a type of deviant behaviors, that are characterised by persistent monitoring and information gathering through online social medias.

Attribute reduction in rough sets theory has been widely used in classication. Classical attribute reduction algorithm only considers correlation between condition attributes and decision attributes, which ignores the relationship among condition attributes themselves. Moreover, when faced with large-scale data, running time of classical attribute reduction algorithm has been increasing. Aiming to solve these two problems, a parallelized reduction algorithm called P-CCARough Reduction is proposed in this paper. The algorithm employs canonical correlation analysis named CCAFusion and parallelized attribute reduction algorithm named P RoughReduction. CCAFusion divides the original set of attributes into two subsets randomly. Then the correlations of these two subsets of features are analyzed. After that, the attributes are fused into one collection according to the derived correlations.

A career path is necessary for students and workers to keep themselves in track for their career goal. However, a career path following a job standard in general is very rare. This paper presents a method to find a semantic similarity within competencies of Job positions for realising a path to relate career. By a development of Thai WordNet containing terms used in competency description, a distance of classes of WordNet structure is used to determine a semantic similarity of comp tencies. Paths to relate job positions are assumed for the job positions sharing similar competencies, and the more they share, the more transferrable job is viable. From the usage scenario, the proposed framework proved that semantic of words is more useful than using character based similarity in competency comparison. Keywords: Career Path * Semantic Similarity * WordNet * Competency 164 PRICAI/PRIMA/PKAW 2016 Program Book A multi-objective adaptive Invasive Weed Optimization intelligence approach for solving DNA sequence design Qiang Zhang*, Gaijing Yang, Changjun Zhou, Bin Wang Key Laboratory of Advanced Design and Intelligent Computing (Dalian university), Ministry of Education, Dalian, 116622, China [email protected] Abstract. DNA sequence design is a key factor to ensure the success of DNA computing. In order to make the DNA computing more reliable, many studies have focused on the DNA sequence design. DNA sequence design relates to several and conflicting design criteria, in this paper, DNA sequence design is formulated as a multi-objective optimization problem, and solved by using a multi-objective adaptive Invasive Weed Optimization intelligence approach (MA_IWO for short). Concretely speaking, our approach (MA_IWO) generates reliable DNA sequences with the consideration of six different conflicting design criteria by introducing the fast non-dominated sorting. Moreover, adaptive mechanism is introduced into the reproduction phase of the Invasive Weed Optimization algorithm (IWO for short), so that the standard deviation of each generation can be changed adaptively according to the fitness value. In addition, our results are validated by comparison with other related works published in the literature. What can be concluded is that the novel approach presented in the paper obtains very satisfactory results which significantly surpass the other previously published results. Keywords: DNA sequence design; DNA computing; IWO algorithm; fast nondominated sorting. 165 PRICAI/PRIMA/PKAW 2016 Program Book A Regression-based SVD Parallelization using Overlapping Folds for Textual Data Uraiwan Buatoom, Thanaruk Theeramunkong, and Waree Kongprewechnon School of Information, Communication and Technology, Sirindhorn International Institute ofTechnology, Thammasat University, Thailand [email protected],[email protected] [email protected], [email protected] Abstract. One of the most difficult issues in text mining is high dimensionality caused by a large number of features (keywords). While various multivariate analyses, such as PCA and SVD (in information retrieval, called LSI), are developed to solve this curse of high dimensionality, they are computationally costly. This paper investigates a regression-based reconstruction method that enables parallelization of PCA/ SVD by decomposing a document-term matrix into a set of sub-matrices with consideration of overlapped terms, and then to re-assemble using regression technique. To evaluate our method, we utilize two text datasets in the UCI Machine Learning Repository, called “Bag of Words” and “Reuter 50 50”. To measure the closeness between two documents, cosine similarity is applied while the accuracy is measured in the form of rank order mismatch. Finally, the result shows that, the matrices decomposition and reassembly can preserve the quality of relation/representation.

In the construction of computational models to recognize emotional state, emotion reporting continuously in time is essential based on the assumption that emotional responses of a human to certain stimuli could vary over time. However, currently existing methods to annotate emotion in temporal continuous fashion are confronting various types of challenges. Therefore, the manipulation of the annotated emotion prior to labeling training samples is necessary. In this work, we present an early attempt to manipulate the emotion annotated in arousal-valence space by applying three dierent signal ltering techniques to smooth annotation data; moving average lter, Savitzky-Golay lter, and median lter. We conducted experiments of emotion recognition in music listening tasks employing brainwave signals recorded from an electroencephalogram (EEG). Smoothed annotation data were used to label the features extracted from EEG signals to train emotion recognizers using classication and regression techniques. Our empirical results indicated the potential of the moving average lter that could increase the performance of emotion recognition evaluated in subject-independent fashion.

Diabetic retinopathy, which can lead to blindness, has been found in 22 percent of diabetic patients in the latest survey. Therefore, diabetic patients should have an eye examination at least once a year. However, it has been found that currently there is a problematic lack of specialists in ophthalmology. Detection and treatment of diabetic retinopathy are thus delayed. The idea to create a classification system of diabetic retinopathy stages to facilitate the making of preliminary decisions by ophthalmologists is introduced. This paper presents the classification of diabetic retinopathy stages using image segmentation and an artificial neural network. This proposed method applies local thresholding to separate the foreground region from the background region so that the optic disc and exudate regions are able to be identified more clearly. The experiment was carried out with 100 fundus images from the Institute of Medical Research and Technology Assessment database. The prediction model had an accuracy rate of up to 96 percent.

Generally, computer-based tutoring system is less engaging compared to human tutoring due to its “insensitiveness” to learners’ affect. A truly intelligent tutoring system (ITS) will take into consideration the learner’s state, and adapt to that state before providing an appropriate learning content or feedback to improve learning. However, an ITS needs to rstly understand the learner’s state and his/her environment. This step is crucial to give appropriate feedback. This study focused on the four (4) frequent emotions attached to learning, which are frustration, boredom, uncertainty and neutral. Using several existing task-based features from previous studies centered in the west, combined with new features from our study, we constructed a four-class localized computational model of affect detection in learning through machine learning approach. The features collected were evaluated with several standard classiers. Results revealed that the J48 classier learned best when evaluated using the task-based features using a host e-tutorial that was especially developed for evaluation purposes.

Education timetabling problem is a problem of arranging exams so that there will not be a clash with the objective of using a minimum number of time slots. It is a combinatorial optimization problem which has been studied by different authors. For combinatorial problems in general, and educational timetabling problem in particular, different metaheuristic algorithms have been proposed and used. Some of these algorithms are originally proposed for continuous problems and later extended for combinatorial optimization problems and are found to have a promising performance. Based on the well-known ‘no free lunch theorem’, there is no superior algorithm for all problem domains. This implies that if an algorithm performs better than another algorithm in some problems or problem domain then there exist another set of problems or problem domains in which it will be out performed. Hence, having different approaches to deal with these problems is advantageous, while how to choose an algorithm for a problem at hand remains to be a research to be studied further. Hence, in this paper, prey predator algorithm will be modified to suit combinatorial optimization problems in general, and educational exam timetabling in particular, with adapted local search mechanism which guides the search over the constrained set of solutions. In order to test the approach five problem instances are chosen from Carter uncapacitated exam timetabling benchmark problem. These problem are well known benchmark problems for high dimensional combinatorial optimization problems. Simulation results show that the proposed approach is promising and comparable with previous approaches.

The aims of project are to develop an arithmetic program that can detect irregularity in electrocardiogram (ECG) and classify between two groups of normal and supraventricular ECG waveforms by using Auto regressive (AR) estimators with various model orders starting from 3rd to 9th. All AR estimators are associated with the PSD of ECG waveforms collected from a group of 30 subjects at 200Hz sampling frequency. The best classification scores found on the 5th-order AR model are 95.99% and 72.17% obtained from training and testing the C4_5 classifier with the fifth-order coefficients. By classifying the 7th-order AR coefficients with Linear Least Squared (LS) classifier the accurate scores of 86.43% and 80.85% were obtained from training and testing cases respectively. These performance accuracies show that the proposed method is highly effective in parameterizing and classifying PSD feature as quantitative measure that can characterize the ECG signals of normal and supraventricular cardiac conditions.

Extraction of relations and their semantic relations from a clinical text is significant to comprehend the actionable harmful and beneficial events between two clinical entities. Particularly to implement drug safety surveillance, two simplest but most important semantic relations are adverse drug reaction and therapeutic indication. In this paper, a method to identify such semantic relations is proposed. A large scale of nearly 1.6 million sentences over 50,998 discharge summary from Electronic Medical Records were preliminary explored. Our approach provided the three main contributions; (i) Electronic Medical Records characteristic exploration; (ii) OpenIE examination for clinical text mining; (iii) automatic semantic relation identification. In this paper, the two complementary information from public knowledge base were introduced as a comparative advantage over expert annotation. Then the set of relation patterns were qualified with 0.05 significant level. The experimental results show that our method can identify the common adverse drug reaction and therapeutic indication with the high lift value. Additionally, a novel adverse drug reaction and alternative drug for a specific symptom therapy are reported to support the comprehensive further drug safety surveillance. The paper clearly illustrates that our method is not only effortless from expert annotation, automatic pattern–specific semantic relation extraction, but also effective for semantic relation identification.

We address the problem of extracting and characterizing functional communities consisting of functional similar regions in spatial networks such as urban streets. Such characteristics of regions will play important roles for developing and planning city promotion, travel tours and so on, as well as understanding and improving the usage of urban streets. In order to analyze such functionally similar regions, based on a previous algorithm for extracting functional communities for each network, we propose a new method consisting of a technique for simultaneously comparing these functional communities of several networks, and an effective way of visualizing these communities calculated from OpenStreetMap data, by especially focusing on a fact that the maximum degree of nodes in spatial networks is restricted to relatively small numbers. In our experiments using urban streets of six cities, we show that our method can produce a series of useful visualization results accompanied with interpretable functional communities. Moreover, we empirically conrm that our results are substantially different from those obtained by representative centrality measures. 183 PRICAI/PRIMA/PKAW 2016 Program Book Fatigue Classification of Military Mission by EEG signals via Artificial Neural Network (ANN) Worawut Yimyam1, and Mahasak Ketcham2 1Department of Computer Business, Phetchaburi Rajabhat University, Thailand [email protected] 2Department of Information Technology Management, king Mongkut’s University of Technology North Bangkok, Thailand [email protected] Abstract.

Web short texts have been increasingly available in the past few years but conventional approaches to text classification are not suitable for short texts due to the data sparseness problem. In this work, we propose a novel rep-resentation learning method to tackle this challenge. Our key idea is to learn re-liable low-dimensional dense representations for short text data based on latent word representations that capture semantics of words over corpus. To efficiently build the word representations, we first compute term similarity based on Word2vec, a deep learning tool that learns semantic vectors of words. We then learn a latent space of individual words from term similarity information using sparse autoencoder. By using the latent word space, we learn feature vectors for short documents based on error minimization. We conduct experiments on the two classification tasks: sentiment text classification and news title classifi-cation to evaluate the proposed method. Experimental results on two real-world datasets demonstrate that our proposed method produces more stable features that enhance short-text classification than state-of-the-art latent feature repre-sentations.

Zakir Hossan, Tanjina Piash Proma, M. Ashraful Amin Computer Vision and Cybernetics Group, Department of Computer Science and Engineering, Independent University, Bangladesh, Bashundhora R/A, Dhaka, Bangladesh [email protected], [email protected], [email protected] Abstract. It is often the case that prescription pills do not come with blister or alu alu packaging where the identity of the pill is available, rather it comes in air-tight plastic bottles or labeled Ziploc bags. Problem with such bottle or pack is that, if the label is removed then it becomes difficult to tell what the pill is. Moreover, there is the issue of visually impaired people having difficulty identifying pills outside the pack. There are such many scenarios where it is good to have an automated pill recognition system. Due to the large variety of size, shape, color, texture it is a difficult task for human to tell about the identity of any individual medical pill. To localize a pill from a given dataset using computer vision techniques requires multiple steps. This paper will describe how to split a dataset according to the shape of pill. To find the shape information we used intrinsic geometric properties such as: eccentricity, extent and narrowness of pill which can be extracted from image using carefully selected image processing techniques. Reference values of discriminative parameters are determined using ‘RxIMAGE’, National Library of Medicine, USA database. The overall shape discrimination accuracy of the proposed system is 93.75%.

Vea12, Ma. Mercedes T. Rodrigo2 1Mapua Institute of Technology, Makati City, Philippines ([email protected]) 2Ateneo de Manila University, Quezon City, Philippines ([email protected]) Abstract. We developed affective models for detecting negative affective states, particularly boredom, confusion, and frustration, among novice programming students learning C++, using keyboard dynamics and/or mouse behavior. The keystroke dynamics are already sufficient to model negative affect detector. However, adding mouse behavior, specifically the distance it travelled along the x-axis, slightly improved the model’s performance. The idle time and typing error are the most notable features that predominantly influence the detection of negative affect. The idle time has the greatest influence in detecting high and fair boredom, while typing error comes before the idle time for low boredom. Conversely, typing error has the highest influence in detecting high and fair confusion, while idle time comes before typing error for low confusion. Though typing error is also the primary indicator of high and fair frustrations, other features are still needed before it is acknowledged as such.

Together with mobile computing and wearable medical devices, articial intelligence is poised to play an important role in the eld of mental health and stress management. Along with a number of other advancements, using data from dierent data modalities has been shown to be an effective way of building accurate and exible stress mod els. However, recent findings indicate that traditional machine learning techniques may lack the ability to effectively identify salient inter-modal correlations, especially when seemingly unrelated modalities are used concurrently. To examine this effect, in this work we investigated the efficacy of building multimodal stress models using a combination of psychological and physiological data. A monitoring platform was built and unobtrusive wearable sensors were used to gather data from sub- jects engaged in authentic work activities. The nal models were cre- ated by combining psychological data from stress coping proles and physiological signals from the wearable sensors. Finally, self-annotated stress annotations to establish the ground truths used for model training. A performance comparison was made between standard machine learning approaches and unsupervised latent feature learning, including deep learning architectures. The results indicate that signicant improve- ments can be achieved by applying deep multimodal feature learning to construct mental stress models.

We propose a method to analyse travellers’ behaviour using automatically identified travellers’ attributes, such as gender and language, from travel blog entries. We consider that travel blog entries are a useful information source for obtaining travel information, because many bloggers’ describe their travel experiences in them. Several studies have analysed travellers’ behaviour using travel blog entries. However, they used a small number of manually identified travellers’ (bloggers’) attributes. In our work, we identify travellers’ attributes automatically using natural language processing techniques, and conduct a large-scale travellers’ behaviour analysis.

Tourism can be defined as the commercial organization and operation of holidays and visits to places of interest. The need of visiting tourism places has increased through time with the practice of tourism and globalization. According to UNWTO’s long term forecast Tourism Towards 2030, international tourist arrivals worldwide are expected to increase by 3.3% a year between 2010 and 2030 to reach 1.8 billion by 2030. Tourism contributes for the development of a country due to its contribution to GDP, employment, exports and investment. From a tourists perspective, a tourist needs to visit as many tourist destinations as possible with a budget constraint. In this paper, the problem is formulated as a travel salesman problem in which a tourist want to visit each of known tourist destination once. We assume that the cost of traveling is as a function of the distance traveled. Therefore, the problem will be minimization the travel time or distance while visiting the intended destinations. In addition tourist destinations are aggregated continent wise and geographically, as called clusters in this paper. Hence, the travel salesman problem will involve another travel salesman problem for each cluster of tourism destination. Prey predator algorithm will be used to solve the proposed approach.

Variant Annotation and Clinical Interpretation Software for Cancer (VARCIN) is a report generating software for producing an executive summary for a cancer patient. The report can assist physicians and researchers by using the result to find a specific or recommended medicine for each specific individual with cancer, known as “Targeted Therapy”, much more efficient. This software can shorten the process and provide an all-in-one solution for classifying and recommending treatments for cancer patients. Moreover, this software is developed as a web-based application with a responsive feature, so this software can be used anywhere and with any electronics device that has an access to a web browser with internet connection, improving ease-of-access thus more convenient than the traditional way.

One of the treatment methods for phobias is behavioral therapy by creating patient’s fear environment for the patient to confront that situation. Virtual reality is one of the most interesting technologies for creating three-dimensional virtual environments. The virtual reality technology makes users feel like they are immersed in a virtual world. To accomplish creating fear environment, this paper presented a virtual reality system with a smartphone application for height exposure. The virtual reality system is simple, which consists of software and hardware. Users can use this system easily in their own home. With an evaluation on 20 participants, the impact of user involvement on realism and fear of heights was explored. Paired samples t-test showed that the user’s influence on the height of the building was significant. Moreover, the user’s influence on the realism and fear of heights when the sound is activated were significant.

In this paper we propose a model that supports the emergence of norms via multiagent learning in a social network. In our model, individual agents repeatedly interact with its neighbors over a given game, the Ali baba and Thief game. An agent learns its strategy to play the game using the learning rule imitatethe-best. Our results show that some norms prohibiting harmful behaviors such as “you should not rob” can emerge after repeated interactions among agents inhabited in certain social networks. Our experimental results suggest that there is critical points of norm emergence which is decided by quotient of the initial utility and the amount of robbery in the Ali baba and Thief game. When the quotient of the initial utility and the amount of robbery is smaller than the critical point, the probability of norm emerge is high. The probability drops dramatically as long as the quotient of the initial utility and the amount of robbery is larger than the critical point. Analyzing Topics and Trends in the PRIMA Literature Hoa Khanh Dam and Aditya Ghose School of Computing and Information Technology University of Wollongong New South Wales 2522, Australia {hoa,aditya}@uow.edu.au Abstract. This study investigates the content of the literature published in the proceedings of the International Conference on Principles and Practices of MultiAgent Systems (PRIMA). Our study is based on a corpus of the 611 papers published in eighteen PRIMA proceedings from 1998 (when the conference started) to 2015. We have developed an unsupervised topic model, using Latent Dirichlet Allocation (LDA), over the PRIMA corpus of papers to analyze popular topics in the literature published at PRIMA in the past eighteen years. We have also analyzed historical trends and examine the strength of each topic over time. 202 PRICAI/PRIMA/PKAW 2016 Program Book Argumentation Versus Optimization for Supervised Acceptability Learning Hiroyuki Kido The University of Tokyo 7-3- 1 Hongo, Bunkyo-ku, Tokyo 113-8656, Japan [email protected] Abstract. This paper deals with the question of how one should predict agent’s psychological opinions regarding acceptability statuses of arguments. We give a formalization of argumentation-based acceptability learning (ABAL) by introducing argument-based reasoning into supervised learning. A baseline classifier is defined based on an optimization method of graph-based semi-supervised learning with dissimilarity network where neighbor nodes represent arguments attacking each other, and therefore, the optimization method adjusts them to have different acceptability statuses. A detailed comparison between ABAL instantiated with a decision tree and naive Bayes, and the optimization method is made using each of 29 examinees’ psychological opinions regarding acceptability statuses of 22 arguments extracted from an online discussion forum. We demonstrate that ABAL with the leave-one-out cross-validation method shows better learning performance than the optimization method in most criteria under the restricted conditions that the number of training examples is small and a test set is used to select the best models of both methods. 203 PRICAI/PRIMA/PKAW 2016 Program Book Argumentation-Based Semantics for Logic Programs with First-Order Formulae Phan Minh Dung1, Tran Cao Son2, and Phan Minh Thang3 1Department of Computer Science, Asian Institute of Technology, Thailand 2Department of Computer Science, New Mexico State University, Las Cruces, NM, USA 3Department of Computer Science, Burapha University International College, Thailand Abstract. This paper studies different semantics of logic programs with first order formulae under the lens of argumentation framework. It defines the notion of an argumentation-based answer set and the notion of an argumentation-based well-founded model for programs with first order formulae. The main ideas underlying the new approach lie in the notion of a proof tree supporting a conclusion given a program and the observation that proof trees can be naturally employed as arguments in an argumentation framework whose stable extensions capture the program’s well-justified answer semantics recently introduced in [23]. The paper shows that the proposed approach to dealing with programs with first order formulae can be easily extended to a generalized class of logic programs, called programs with FOL-representable atoms, that covers various types of extensions of logic programming proposed in the literature such as weight constraint atoms, aggregates, and abstract constraint atoms. For example, it shows that argumentation-based well-founded model is equivalent to the well-founded model in [27] for programs with abstract constraint atoms. Finally, the paper relates the proposed approach to others and discusses possible extensions. 204 PRICAI/PRIMA/PKAW 2016 Program Book Automatic Evacuation Management using a Multi Agent System and Parallel Meta-heuristic Search Leonel Aguilar, Maddegedara Lalith, Tsuyoshi Ichimura, and Muneo Hori Earthquake Research Institute, The University of Tokyo, Bunkyo, Tokyo 113-0032 leaguilar,lalith,ichimura,[email protected] Abstract. An automatic evacuation management system taking advantage of a multi agent base mass evacuation simulator is proposed and prototyped. The aim of this system is to provide a stepping stone in the direction of automated evacuation managing. The proposed system is currently capable of identifying evacuation anomalies, proposing a mitigation strategy and providing feedback for human expert evaluation and query. All the pieces although seamlessly connected are independently developed. This allows their independent improvement and evaluation. This paper provides an overview of the developed automatic evacuation management system and all of its components, a demonstrative example, and discussion of its current limitations and future development direction. The demonstrative example shows increases of more than 10% in the evacuation throughput by using the proposed system. Balancing Rationality and Utility in Logic-Based Argumentation with Classical Logic Sentences and Belief Contraction Ryuta Arisaka and Ken Satoh National Institute of Informatics [email protected], [email protected] Abstract. Compared to abstract argumentation theory which encapsulates the exact nature of arguments, logic-based argumentation is more specific and represents arguments in formal logic. One significant advantage of logic-based argumentation over abstract argumentation is that it can directly benefit from logical properties such as logical consistency, promoting adherence of an argumentation framework to rational principles. On the other hand, a logical argumentation framework based on classical logic has been also reported of its less-than- desirable utility. In this work we show a way of enhancing utility without sacrificing so much of rationality. We propose a rational argumentation framework with just classical logic sentences and a belief contraction operation. Despite its minimalistic appearance, this framework can characterise attack strengths, allowing us to facilitate coalition profitability and formability semantics we previously defined for abstract argumentation. 205 PRICAI/PRIMA/PKAW 2016 Program Book Can noise in behavioral models improve macro-predictions? An empirical test Michael Mäs1 and Dirk Helbing2 1Department of Sociology / ICS, University of Groningen Grote Rozenstraat 31, 9712 TG Groningen, The Netherlands 2Chair of Computational Social Science, ETH Zurich Clausiusstrasse 50, 8092 Zurich, Switzerland Abstract. In the past decades, we have experienced a vast improvement of theories of human behavior. Nevertheless, our ability to predict the behavior of human groups, organizations, and societies has remained limited. For instance, the last financial crisis and the Arab Spring took most scientists and experts by surprise, although theories describe with increasing accuracy the decision-making patterns of individual stock-traders and political activists. With two laboratory experiments, we tested whether collective phenomena can be critically shaped by random deviations from otherwise prevalent patterns of individual behavior. In our experiments, 96 percent of participants’ decisions were in line with a deterministic standard theory of rational decision-making. Despite this impressive microlevel accuracy, the deterministic model fails to predict the observed macro-outcomes.However, we find that a stochastic version of the same micro-theory, which adds random deviations, largely improves macro-predictions. Our results show that deviations can spark cascades, which fundamentally shape macro-outcomes. The stochastic model also correctly predicted the conditions under which deviations induced system shifts.Additionally, we observed non-random deviation patterns. Our second experiment supported the hypothesis that these systematic deviations can result in fundamentally different macro-outcomes than random deviations. 206 PRICAI/PRIMA/PKAW 2016 Program Book Coalition Structure Formation using Anytime Dynamic Programming Changder Narayan1, Dutta Animesh1, and Ghose Aditya K.2 1National Institute of Technology Durgapur, West Bengal, India [email protected], [email protected] 2University of Wollongong, Wollongong NSW 2522 Australia [email protected] Abstract. The optimal coalition structure generation is an important problem in multiagent systems that remains difficult to solve. This paper presents a novel anytime dynamic programming algorithm to compute the optimal coalition structure. The proposed algorithm can be interrupted, and upon interruption, uses heuristic to select the largest valued coalition from each subproblem of size x and picks the rest of the unassigned agent from other subproblem of size n−x, where n is the total number of agents. We compared the performance of our algorithm against the only existing proposal in the literature for the optimal coalition structure problem that uses anytime dynamic programming using 9 distinct datasets (each corresponding to a different distribution). The empirical evaluation shows that our algorithm always generates better or, at least, as good a solution as the previous anytime dynamic programming algorithm. Competitive VCG Redistribution Mechanism for Public Project Problem Mingyu Guo School of Computer Science University of Adelaide, Australia [email protected] Abstract. The VCG mechanism has many nice properties, and can be applied to a wide range of social decision problems. One problem of the VCG mechanism is that even though it is efficient, its social welfare (agents’ total utility considering payments) can be low due to high VCG payments. VCG redistribution mechanisms aim to resolve this by redistributing the VCG payments back to the agents. Competitive VCG redistribution mechanisms have been found for various resource allocation settings. However, there has been almost no success outside of the scope of allocation problems. This paper focuses on another fundamental model - the public project problem. In Naroditskiy et al. 2012, it was conjectured that competitive VCG redistribution mechanisms exist for the public project problem, and one competitive mechanism was proposed for the case of three agents (unfortunately, both the mechanism and the techniques behind it do not generalize tocases with more agents). In this paper, we propose a competitive mechanism for general numbers of agents, relying on new techniques. 207 PRICAI/PRIMA/PKAW 2016 Program Book Demand Response Integration through Agent-based Coordination of Consumers in Virtual Power Plants Anders Clausen, Aisha Umair, Zheng Ma, and Bo Nørregaard Jørgensen University of Southern Denmark {ancla; aiu; zma; bnj}@mmmi.sdu.dk Abstract. The transition towards an electricity grid based on renewable energy production induces fluctuation in electricity generation. This challenges the existing electricity grid design, where generation is expected to follow demand for electricity. In this paper, we propose a multi-agent based Virtual Power Plant design that is able to balance the demand of energy-intensive, industrial loads with the supply situation in the electricity grid. The proposed Virtual Power Plant design uses a novel interagent, multi-objective, multi-issue negotiation mechanism, to coordinate the electricity demands of industrial loads. Coordination happens in response to Demand Response events, while considering local objectives in the industrial domain. We illustrate the applicability of our approach on a Virtual Power Plant scenario with three simulated greenhouses. The results suggest that the proposed design is able to coordinate the electricity demands of industrial loads, in compliance with external Demand Response events. Dialectical Proof Procedures for Probabilistic Abstract Argumentation Phan Minh Thang BUUIC College, Burapha University, Thailand Abstract.

In this paper, we introduce a specific form of graded group responsibility called “distant responsibility” and provides a formal analysis for this concept in multi-agent settings. This concept of responsibility is formalized in concurrent structures based on the power of agent groups in such structures. A group of agents is called responsible for a state of affairs by a number of collective decision steps if there exists a strategy for the agent group to preclude the specified state of affairs in the given number of steps. Otherwise, the group is partially responsible based on its maximum contribution to fully responsible groups. We argue that the notion of distant responsibility is applicable as a managerial decision support tool for allocation of limited resources in multi-agent organizations. 209 PRICAI/PRIMA/PKAW 2016 Program Book Generalising Social Structure using Interval Type-2 Fuzzy Sets Christopher K.

Purvis2, and Mariusz Nowostawski3 1College of Enterprise and Development, Otago Polytechnic, New Zealand [email protected] 2Department of Information Science, University of Otago, New Zealand {tony.savarimuthu, martin.purvis}@otago.ac.nz 3Faculty of Computer Science and Media Technology, Norwegian University of Science and Technology, Norway [email protected] Abstract. To understand the operation of the informal social sphere in human or artificial societies, we need be able to identify their existing behavioural conventions (institutions). This includes the contextualisation of seemingly objective facts with subjective assessments, especially when attempting to capture their meaning in the context of the analysed society An example for this is numeric information that abstractly expresses attributes such as wealth, but only gains meaning in its societal context. In this work we present a conceptual approach that combines clustering techniques and Interval Type-2 Fuzzy Sets to extract structural information from aggregated subjective micro-level observations. A central objective, beyond the aggregation of information, is to facilitate the analysis on multiple levels of social organisation. We introduce the proposed mechanism and discuss its application potential. 210 PRICAI/PRIMA/PKAW 2016 Program Book Heuristics on the Data-collecting Robot Problem with immediate rewards Zhi Xing and Jae C. Oh Electrical Engineering and Computer Science, Syracuse University {zxing01,jcoh}@syr.edu Abstract. We propose the Data-collecting Robot Problem, where robots collect data as they visit nodes in a graph, and algorithms to solve it. There are two variations of the problem: the delayed-reward problem, in which robots must travel back to the base station to deliver the data collected and to receive rewards; and the immediate-reward problem, in which the reward is immediately given to the robots as they visit each node. The delayed-reward problem is discussed in one of the authors’ work. This paper focuses on the immediate-reward problem. The solution structure has a clustering step and a tour-building step. We propose Progressive Gain-aware Clustering that finds good quality solutions with efficient time complexity. Among the six proposed tour-building heuristics, Greedy Insertion and Total-Loss algorithms perform best whendata rewards are different. 211 PRICAI/PRIMA/PKAW 2016 Program Book How, When and Where Can Spatial Segregation Induce Opinion Polarization? Two Competing Models Thomas Feliciani1, Andreas Flache1, Jochem Tolsma2 1ICS / Department of Sociology, University of Groningen, Groningen, The Netherlands. 2ICS / Department of Sociology, Radboud University, Nijmegen, The Netherlands. Abstract. Increasing ethnic diversity fosters scholarly interest in how the spatial segregation of groups affects opinion polarization in a society. Despite much empirical and theoretical research, there is little consensus in the literature on the causal link between the spatial segregation of two groups and the emergence of opinion polarization. We contribute to the debate by investigating theoretically the conditions under which the former fosters or hinders the latter. We focus on two processes of opinion polarization (negative influence and persuasive argument communication) that, according to previous modeling work, can be expected to make conflicting predictions about the relationship between segregation and opinion polarization. With a Schelling-type ABM of residential segregation, we generate initial environments with different levels of group segregation. Then we simulate the two processes of opinion dynamics. We show that the negative influence model predicts segregation to hinder the emergence of opinion polarization. On the other hand, the persuasive argument model predicts that segregation does not substantially foster polarization. Moreover, we explore how the spatial patterns of opinion distribution differ between the models: in particular, we investigate the likelihood that group membership and opinion align. We show that the alignment of group membership and opinions differs between the two opinion formation models, and that the scale at which we measure alignment plays a crucial role. 212 PRICAI/PRIMA/PKAW 2016 Program Book Individually Rational Strategy-proof Social Choice with Wxogenous InDifference Sets Mingyu Guo1, Yuko Sakurai2, Taiki Todo2, and Makoto Yokoo2 1The University of Adelaide 2Kyushu University [email protected], {ysakurai, todo, yokoo}@inf.kyushu-u.ac.jp Abstract. We consider a social choice problem where individual rationality is required. The status quo belongs to the outcome space, and the selected alternative must be weakly better than the status quo for everybody. If the mechanism designer has no knowledge of the alternatives, we obtain a negative result: any individually rational (IR) and strategy-proof (SP) mechanism can choose at most one alternative (besides the status quo), regardless of the preferences. To overcome this negative result, we consider a domain where the alternatives have a known structure, i.e., an agent is indifferent between the status quo and a subset of the outcomes. This set is exogenously given and public information. This assumption is natural if the social choice involves the participation of agents. For example, consider a group of people organizing a trip where participation is voluntary. We can assume each agent is indifferent between the trip plans in which she does not participate and the status quo (i.e., no trip). In this setting, we obtain more positive results: we develop a class of mechanisms called Approve and Choose mechanisms, which are IR and SP, and can choose multiple alternatives as well as the status quo. 213 PRICAI/PRIMA/PKAW 2016 Program Book Modeling Organizational and Institutional Aspects in Renewable and Natural Resources Management Context Islem Hènane1, Sameh Hadoua25, Khaled Ghédira3, Ali Ferchichi4 1National School of Computer Sciences, Manouba University, Manouba, Tunisia 2Faculty of Economics and Management, Carthage University, Nabeul, Tunisia 3Higher Institute of Management, Tunis University, Tunis, Tunisia 4National Agronomic Institute, Carthage University, Tunisia 5Higher Colleges of Technology, Abu Dhabi, United Arab Emirates {islemhenane, hadouaj}@yahoo.fr, [email protected],[email protected] Abstract. Since 1990, there has been a striking increase in using multi-agent systems to study renewable resources management systems. The ultimate objective is to contribute to decisions support on resources management. The adopted strategic decisions are always joined with access to resources norms. However, the defined norms are statics and suppose that all agents are not autonomous and always obey to the underlying norms which do not reflect reality. In previous work, we proposed ML-MA [1], a multi-level multi- agent architecture to support renewable resources management systems modeling. In this work, we focus on the integration of normative aspects in our architecture. Our approach is illustrated using “Ouled Chehida” case study from Tunisian pastoral context. 214 PRICAI/PRIMA/PKAW 2016 Program Book Offer Evaluation and Trade-off Making in Automated Negotiation Based on Intuitionistic Fuzzy Constraints Jieyu Zhan and Xudong Luo Institute of Logic and Cognition, Department of Philosophy, Sun Yat-sen University, Guangzhou, 510275, China. Abstract. In automated negotiation, one of crucial problems is how a negotiating agent evaluates the acceptability of an offer. Most models mainly use two kinds of evaluation methods: (i) linear utility functions that depend on issues, and (ii) nonlinear utility functions that depend on crisp constraints. However, in real life, it is hard for human users to input so much and so accurate information that these evaluation methods require. To this end, this paper proposes a new approach for offer evaluation where human users are allowed to input indeterminate information. More specifically, we propose a framework of prioritised intuitionistic fuzzy constraint satisfaction problems for modelling agent’s goals. Moreover, we take both satisfaction degree and dissatisfaction degree into consideration when calculating an agent’s acceptability of an offer. Finally, we discuss how to make trade-offs via similarity measure based on intuitionistic fuzzy criteria functions.

While most robots in human robot interaction scenarios take instructions from humans, the ideal would be that humans and robots collaborate with each other. The Defense Advanced Research Projects Agency Communicating with Computer program proposes the collaborative blocks world scenario as a testbed for this. This scenario requires the human and the computer to communicate through natural language to build structures ou of toy blocks. To formulate and address this, we identify two main tasks. The first task, called the plan failure analysis, demands the robot to analyze the feasibility of a task and to determine the reasons(s) in case the task is not doable. The second task focuses on the ability of the robot to understand communications via natural language. We discuss potential solutions to both problems and present prototypical architecture for the integration of planning failure analysis and natural language communication into an intelligent agent architecture. 215 PRICAI/PRIMA/PKAW 2016 Program Book Resistance to Corruption of General Strategic Argumentation Michael J. Maher School of Engineering and Information Technology University of New South Wales, Canberra ACT 2600, Australia E-mail: [email protected] Abstract. [16, 18] introduced a model of corruption within strategic argumentation, and showed tha some forms of strategic argumentation are resistant to two forms of corruption: collusion and espionage. Such a model provides a (limited) basis on which to trust agents acting on our behalf. However, that work only addressed the grounded and stable argumentation semantics. Here we extend this work to several other well-motivated semantics. We must consider a greater number of strategic aims that players may have, as well as the greater variety of semantics. We establish the complexity of several computational problems related to corruption in strategic argumentation, for the aims and semantics we study. From these results we identify that strategic argumentation under the aims and semantics we study is resistant to espionage. Resistance to collusion varies according to the player’s aim and the argumentation semantics, and we present a complete picture for the aims and semantics we address. 216 PRICAI/PRIMA/PKAW 2016 Program Book Revenue Maximizing Markets for Zero-Day Exploits Mingyu Guo1, Hideaki Hata2, and Ali Babar1 1School of Computer Science University of Adelaide, Australia {mingyu.guo, ali.babar}@adelaide.edu.au 2Graduate School of Information Science Nara Institute of Science Technology, Japan [email protected] Abstract. Markets for zero-day exploits (software vulnerabilities unknown to the vendor) have a long history and a growing popularity. We study these markets from a revenue-maximizing mechanism design perspective. We first propose a theoretical model for zero-day exploits markets. In our model, one exploit is being sold to multiple buyers. There are two kinds of buyers, which we call the defenders and the offenders. The defenders are buyers who buy vulnerabilities in order to fix them (e.g., software vendors). The offenders, on the other hand, are buyers who intend to utilize the exploits (e.g., national security agencies and police). Our model is more than a single-item auction. First, an exploit is a piece of information, so one exploit can be sold to multiple buyers. Second, buyers have externalities. If one defender wins, then the exploit becomes worthless to the offenders. Third, if we disclose the details of the exploit to the buyers before the auction, then they may leave with the information without paying. On the other hand, if we do not disclose the details, then it is difficult for the buyers to come up with their private valuations. Considering the above, our proposed mechanism discloses the details of the exploit to all offenders before the auction. The offenders then pay to delay the exploit being disclosed to the defenders. 217 PRICAI/PRIMA/PKAW 2016 Program Book Semantic Reasoning with Uncertain information from Unreliable Sources Murat Şensoy1, Lance Kaplan2, and Geeth de Mel3 1Department of Computer Science, Ozyegin University, Istanbul, TR. 2US Army Research Lab, Adelphi, MD 20783, USA. 3IBM T. J. Watson Research Center, Hawthorne, NY, USA. Abstract. Intelligent software agents may significantly benefit from semantic reasoning. However, existing semantic reasoners are based on Description Logics, which cannot handle vague, incomplete, and unreliable knowledge. In this paper, we propose SDL-Lite which extends DL-Lite R with subjective opinions to represent uncertainty in knowledge. We directly incorporate trust into the reasoning so that the inconsistencies in the knowledge can be resolved based on trust evidence analysis. Therefore, the proposed logic can handle uncertain information from unreliable sources. We demonstrate how SDL-Lite can be used for semantic fusion of uncertain information from unreliable sources and show that SDL- Lite reasoner can estimate the ground truth with a minimal error. Sequence Semantics for Normative Agents Guido Governatori1, Francesco Olivieri2, Erica Calardo3, Antonino Rotolo3, and Matteo Cristani2 1Data61, CSIRO, Australia 2University of Verona, Italy 3University of Bologna, Italy Abstract. We proposed a novel framework for the representation of goals and other mental-like attitudes in terms of degree of expected outcomes, where an outcome is an order of possible alternatives. The sequences of alternatives is modelled by a non-classical (substructural) operator. In this paper we provide a modal logic based axiomatisation of the intuition they propose, and we discuss some variants (in particular for the notion of social intention, intentions that are compliant with norms). Given that the outcome operator is substructural, we first propose a novel sequence semantics (a generalisation of possible world semantics) to model the outcome operator, and we prove that the axiomatisation is sound and complete with respect to the new semantics. 218 PRICAI/PRIMA/PKAW 2016 Program Book Spread of Cooperation in Complex Agent Networks Based on Expectation of Cooperation Ryosuke Shibusawa, Tomoaki Otsuka, and Toshiharu Sugawara Department of Computer Science and Communications Engineering, Waseda University, Tokyo 1698555, Japan [email protected], [email protected], [email protected] Abstract. This paper proposes a behavioral strategy called expectation of cooperation with which cooperation in the prisoner’s dilemma game spreads over agent networks by incorporating Q-learning. Recent advances in computer and communication technologies enable intelligent agents to operate in small and handy computers such as mobile PCs, tablet computers, and smart phones as delegates of their owners. Because the interaction o these agents is associated with social links in the real world, social behavior is to some degree required to avoid conflicts, competition, and unfairness that may lead to further inefficiency in the agent society. The proposed strategy is simple and easy to implement but nevertheless can spread over and maintain cooperation in agent networks under certain conditions. We conducted a number of experiments to clarify these conditions, and the results indicate that cooperation spread and was maintained with the proposed strategy in a variety of networks. 219 PRICAI/PRIMA/PKAW 2016 Program Book Towards Better Crisis Management in Support Services Organizations using Fine Grained Agent Based Simulation Vivek Balaraman, Harshal Hayatnagarkar, Meghendra Singh, Mayuri Duggirala Human Centric Systems, TCS Research, 54-B, Hadapsar Industrial Estate, Pune, India. {vivek.balaraman, h.hayatnagarkar2, meghendra.singh, mayuri.duggirala}@tcs.com Abstract. Critical support service operations have to run 24 x 7 and 365 days a year. Support operations therefore do contingency planning to continue operations during a crisis. In this paper we explore the use of fine-grained agent-based simulation models, which factor in human-behavioral dimensions such as stress, as a means to do better people planning for such situations. We believe the use of this approach may allow support operations managers to do more nuanced planning leading to higher resilience, and quicker return to normalcy. We model a prototypical support operation, which runs into different crisis severity levels, and show for each case, a reasonable size of the crisis team that would be required. We identify two contributions in this paper: First, emergency planning using agent based simulations have mostly focused, naturally, on societal communities such as urban populations. There has not been much attention paid to study crisis responses within support services organizations and our work is an attempt to address this deficit. Second, our use of grounded behavioral elements in our agent models allows us to build complex human behavior into the agents without sacrificing validity. Verifying Real-Time Properties of Multi-Agent Systems via SMT-based Bounded Model Checking Agnieszka M. Zbrzezny and Andrzej Zbrzezny IMCS, Jan Długosz University. Al. Armii Krajowej 13/15, 42-200 Czȩstochowa, Poland. {agnieszka.zbrzezny, a.zbrzezny}@ajd.czest.pl Abstract. We present a satisfiability modulo theories based bounded model checking (SMT-based BMC) method for timed interpreted systems (TIS) and for properties expressible in the existential fragment of a Real-Time Computation Tree Logic with epistemic components (RTECTLK). We implemented the standard BMC algorithm and evaluated it for two multi-agent systems: a timed train controller system and a timed generic pipeline paradigm. Weused the Z3 solver. 220 PRICAI/PRIMA/PKAW 2016 Program Book PRIMA Student Abstracts 221 PRICAI/PRIMA/PKAW 2016 Program Book A Kernelization approach for Anytime Coalition Structure Generation using Knuth X algorithm Narayan Changder, Animesh Dutta, and Aditya Ghose National Institute of Technology, Durgapur University of Wollongong Abstract. Determining the optimal coalition structure is an interesting problem in multi-agent system. The main problem is, after a group of agents comes together, how the agents can be partitioned such that social payoff is maximized? This work presents the application of Knuth X algorithm in coalition structure generation problem. Freight Train Scheduling Problem Samriddhi Sarkar and Animesh Dutta National Institute of Technology Durgapur, India Abstract. In most of the countries, passenger and freight trains share the same infrastructure. However, freight trains are run without any fixed schedule, they are operated as the requirements arise. This paper adopts Timed Colored Petri Nets theory to model the railway system. Proposed system will automatically detect the possible conflicts amongst the freight request and passenger trains’ schedule using various TCPN properties. After that system will try to find out a feasible schedule for the freight train taking into account the safety rules set by railways, that too, without any human intervention. 222 PRICAI/PRIMA/PKAW 2016 Program Book Multi-Agent Based Scalable and Context-Aware Middleware for Typical IoT Scenarios Bikash Choudhury, Subhrabrata Choudhury, and Animesh Dutta National Institute of Technology Durgapur, India Abstract. The objective of the work is to design a multi-agent based distributed middleware forservice oriented computing (SOC) in mobile pervasive environment that improves the QoSof the service consumers with minimal resources usage in the system. From another angle it can also be viewed as a system that enables on-demand self-organised Fog creation in the vicinity of the service consumer that reduces the traffic load at core network and the resource requirement of the cloud servers. Real-time Collision Handling in Railway Network: An Agent-based Approach Poulami Dalapati and Animesh Dutta National Institute of Technology durgapur, India Abstract. This research work addresses the issues concerning collision detection and resolution in a complex railway network. The proposed approach tries to resolve conflicts during runtime in distributed manner satisfying real time constraints using cooperative autonomous agents. The objective function of this constraint satisfaction problem considers early detection of as well as minimization of total number of conflicts in a time interval. 223 PRICAI/PRIMA/PKAW 2016 Program Book Role of Facial Emotion in Social Correlation Pankaj Mishra, Rafik Hadfi, and Takayuki Ito Nagoya Institute of Technology Abstract. Diffusion of information can be found in any social network, either it be a small network of co-workers or large as social networking applications like Facebook, Twitter, LinkedIn, etc. In this paper, we propose a system to analyse the correlation amongst the group of people, by analysing the emotion diffusion of all the participants in the considered network or group. Also, we implement our system in a multi-agent paradigm to maintain the robustness and scalability of the algorithm. Finally, we test our algorithm with the scripted discussion, of which ground truth correlation is known. Such knowledge of the influences among the participants of the network, could be used to find the influential individual; further can find many applications such in consensus, negotiation, viral marketing, etc. Security and Access Control in Multi-Agent Satellite Systems Pratik Sinha and Animesh Dutta National Institute of Technology Durgapur, India Abstract. This research work aims to address the issues related to security and access control in multi-agent satellite systems. The communication among agents and ground stations are prone to interception. Also, agents should perform tasks given by authorized ground stations and agents only. However, ground stations must not be involved repetitively for access control. The proposed work aims to formally model the problem and develop appropriate algorithmic solutions. 224 PRICAI/PRIMA/PKAW 2016 Program Book Selected Methods of Model Checking using SAT and SMT-solvers Agnieszka Zbrzezny Institute Of Mathematics and Computer Science, Jan Dlugosz University in Czestochowa Abstract. The objectives of this research are to further investigate the foundations for novel SMTand SAT-based bounded model checking (BMC) algorithms for real-time and multi-agent systems.

Internet users are always being attacked by spam messages, especially spam e-mails. Due to this issue, researchers had done many research works to find alternatives against the spam attacks. Different approaches, software and methods had been proposed in order to protect the Internet users from spam. This proposed work was inspired by the rough set theory, which was proven effective in handling uncertainties and large data set and also by the soft set theory which is a new emerging parameter reduction method that could overcome the limitation of rough set and fuzzy set theories in dealing with an uncertainty problem. The objective of this work was to propose a new hybrid parameter reduction method which could solve the uncertainty problem and inefficiency of parameterization tool issues which were used in the spam e-mail classification process. The experimental work had returned significant results which proved that the hybrid rough set and soft set parameter reduction method can be applied in the spam e-mail classification process that helps the classifier to classify spam e-mails effectively. As a recommendation, enhancement works on the functionality of this hybrid method shall be considered in different application fields, especially for the fields dealing with uncertainties problem and high dimension of data set. 227 PRICAI/PRIMA/PKAW 2016 Program Book Abbreviation Identification in Clinical Notes with Level-wise Feature Engineering and Supervised Learning Vo Thi Ngoc Chau, Cao Hoang Tru, Ho Tu Bao Abstract. Nowadays, electronic medical records get more popular and significant in medical, biomedical, and healthcare research activities. Their popularity and significance lead to a growing need for sharing and utilizing them from the outside. However, explicit noises in the shared records might hinder users in their efforts to understand and consume the records. One kind of explicit noises that has a strong impact on the readability of the records is a set of abbreviations written in free text in the records because of writing-time saving and record simplification. Therefore, automatically identifying abbreviations and replacing them with their correct long forms are necessary for enhancing their readability and further their sharability. In this paper, our work concentrates on abbreviation identification to lay the foundations for de-noising clinical text with abbreviation resolution. Our proposed solution to abbreviation identification is general, practical, simple but effective with level-wise feature engineering and a supervised learning mechanism. We do level-wise feature engineering to characterize each token that is either an abbreviation or a non-abbreviation at the token, sentence, and note levels to formulate a comprehensive vector representation in a vector space. After that, many open options can be made to build an abbreviation identifier in a supervised learning mechanism and the resulting identifier can be used for automatic abbreviation identification in clinical text of the electronic medical records. Experimental results on various real clinical note types have confirmed the effectiveness of our solution with high accuracy, precision, recall, and F-measure for abbreviation identification. Acquiring Seasonal/Agricultural Knowledge from Social Media Hiroshi Uehara and Kenichi Yoshida Abstract. Agricultural knowledge depends on seasonally changing conditions such as climate, harmful insects, etc. In this respect, farmers tend to be interested in seasonal knowledge rather than the static principle. To acquire such agricultural knowledge, we propose a method to acquire seasonal knowledge from ongoing posts in the social media. The experimental results shows that the agricultural knowledge can be extracted in the form of chained structures, each of which denotes a set of seasonal knowledge. We also developed a prototype of dialogue robot that provides agricultural knowledge based on the chained structure database. The characteristics of the robot is its ability to reply with seasonally changing knowledge. 228 PRICAI/PRIMA/PKAW 2016 Program Book Amalgamating Social Media Data and Movie Recommendation Maria R. Lee, Tsung Teng Chen, Ying Shun Cai Abstract. Recommender systems (RSs) have become very common recently. However, RS techniques need large amounts of user and product data, which hinders RS usage for businesses with insufficient data. The RS cold-start problem may be mitigated by leveraging external data sources. We demonstrate the feasibility of solving the cold-start problem by implementing a hybrid RS that integrates the Facebook Fan Page data and the genre-classifications data from Yahoo! Movies. Our study amalgamates social media data and machine learning to build a hybrid-filtering RS. We also compared our system with three existing movie RSs?those used by Netflix, YouTube, and Amazon. Within the framework of a hybrid-filtering RS, content-based filtering was used to extract data from Yahoo! Movies and Facebook Fan Pages. The proposed RS overcame the cold-start problem and achieved a satisfactory level of accuracy. Building a Mental Health Knowledge Model to Facilitate Decision Support Bo Hu, Boris Villazon Terrazas Abstract. Medical research produces a vast amount of data everyday through for instance high throughput preclinical and clinical tools. Exploiting such a source of knowledge, as well as discovering patterns and relations buried within, can offer great help to clinical professionals in high quality health care services. There is a growing reliance on advanced computing technologies to help make sense and comprehend such data. In this paper, we describe the application of Word2Vec to facilitate knowledge discovery from very-large public unstructured text corpora (worked with PubMed thus far, but can easily incorporate others). Benefit from unsupervised word embedding, we experiment how new knowledge can stem from peer-reviewed medical publications and cross-reference such knowledge with established one to understand the advantages and disadvantages of popular deep-learning based approaches to knowledge acquisition. We also developed a proof-of-concept computer system to exploit such knowledge in a medical recommendation system. 229 PRICAI/PRIMA/PKAW 2016 Program Book Building a Process Description Repository with Knowledge Acquisition Diyin Zhou, Hye-Young Paik, Seung Hwan Ryu, John Shepherd, Paul Compton Abstract. Although there is an abundance of how-to guides online, systematically utilising the collective knowledge represented in such guides has been limited. This is primarily due to how-to guides (effectively, informal process descriptions) being expressed in natural language, which complicates the process of extracting actions and data. This paper describes the use of Ripple-Down Rules (RDR) over the Stanford NLP toolkit to improve the extraction of actions and data from process descriptions in text documents. Using RDR, we can incrementally and rapidly build rules to refine the performance of the underlying extraction system. Although RDR has been widely applied, it has not so far been used with NLP phrase structure representations. We show, through implementation and evaluation, how the use of action-data extraction rules and knowledge acquisition in RDR is both feasible and effective. Building a Working Alliance with a Knowledge Based System through an Embodied Conversational Agent Deborah Richards, Patrina Caldwell Abstract. Knowledge is only useful if the intended user is able to utilize the system. In early knowledge based systems, known as expert systems, the user interface provided the means through which knowledge was acquired and accessed. Today it is possible to interact with the knowledge of an expert through a humanlike interface, in the form of an embodied conversational agent (ECA). Through familiar conversational-style interaction, the ECA can obtain the state of the user and provide a recommendation overcoming health literacy barriers and, depending on the nature of the dialogue, build a working alliance with the human that will encourage adherence to the advice. In this paper we describe the eADVICE system in the domain of paediatric incontinence that aims to improve adherence through the use of an ECA as the interface to the domain knowledge. Results of an initial pilot are provided showing that those who used the ECA achieved improved health outcomes and found the experience positive. 230 PRICAI/PRIMA/PKAW 2016 Program Book Combining Feature Selection with Decision Tree Criteria and Neural Network for Corporate Value Classification Ratna Hidayati; Katsutoshi Kanamori; Ling Feng; Hayato Ohwada Abstract. This study aims to classify corporate values among Japanese companies based on their corporate social responsibility (CSR) performances. Since there are many attributes in CSR, feature selection with decision tree criteria is used to select the attributes that can classify corporate values. The feature selection found that 41% of 37 total attributes, or only 15 attributes, are needed to classify corporate values. The accuracy of building the tree used to find the 15 attributes is low. To increase the accuracy, the attributes are trained in a neural network. The accuracy of the decision tree is 0.7, and the accuracy of the neural for training the 15 attributes increased to 0.75. To sum up, this study found, companies with higher corporate values seek to enhance their CSR activities or to empower secondary stakeholders. In contrast, companies with low corporate values still focus their CSR activities on primary stakeholders. Competition Detection from Online News Zhong-Yong Chen and Chien Chin Chen Abstract. In this paper, we define a novel problem named competed intention identification of online news. We propose new features to represent the competed intention of the documents. The support vector machine (SVM) is employed to adopt our features to identify the competed intention in the news article. Experimental results demonstrate that the features we designed are effective for identifying the documents with competed intention. 231 PRICAI/PRIMA/PKAW 2016 Program Book Enhanced Rules Application Order to Stem Affixation, Reduplication and Compounding Words in Malay Texts Mohamad Nizam Kassim, Mohd Aizaini Maarof, Anazida Zainal, Amirudin Abdul Wahab Abstract. Word stemmer is an automated program to remove affixes, clitics and particles from derived words based on morphological structures of specific natural languages. It has been widely used for text preprocessing in many artificial intelligence applications. Furthermore, the performance of word stemmer to correctly stem derived words has an influence to the performance of information retrieval, text mining and text categorization applications. Despite of various stemming approaches were proposed in the past research, the existing word stemmers for Malay language still suffer from stemming errors. Moreover, the existing word stemmers partially consider morphological structures of Malay language in which only focused on affixation words instead of affixation, reduplication and compounding words, simultaneously. Therefore, this paper proposes an enhanced word stemmer using rule-based affixes removal and dictionary lookup methods called enhanced rule application that is able to stem affixation, reduplication and compounding words and at the same time, is able to address possible stemming errors. This paper also examines possible root causes of affixation, reduplication and compounding stemming errors that could happen during word stemming process. The experimental results indicate that the proposed word stemmer is able to stem affixation, reduplication and compounding words with better stemming accuracy by using enhanced rule application order. Finding Reliable Source for Event Detection Using Evolutionary Method Raushan Ara Dilruba and Mahmuda Naznin Abstract. Participatory sensing is a phenomenon where participants use mobile phones or social media and feed data to detect an event. Since, data gathering is open to many participants, one of the major challenges of this type of networks is to identify truthfulness of the reported observations. Finding the reliable sources is a challenging task since the node or participant’s reliability is unknown or even the probability of the reported event to be true is also unknown. In our paper, we study this challenge and observe that applying evolutionary method, we can identify reliable source nodes. We call our approach Population Based Reliability Estimation. We validate our claim by experimental results. We also compare our method with another widely used method. From experiments we find that our approach is more efficient. 232 PRICAI/PRIMA/PKAW 2016 Program Book Improving Motivation in Survey Participation by Question Reordering Rohit Kumar Singh, Vorapong Suppakitpaisarn, and Ake Osothongs Abstract. We organized an experiment to show that survey participants take part more when the questionnaires started with less aggressive questions. In our earlier work, we used Bayesian probability and graph algorithms to find relative values of each personal attribute. Using that valuation, we created two sets of the questionnaire each differs in question order and ask 33 personal attributes from participants. The first set of the questionnaire ordered questions from personal attributes with high valuations such as passport number, driving license number, last name, and monthly income to personal attributes with low valuations such as nationality, gender and office country. On the other hand, the second set of questionnaire ordered from those with low valuations to those with higher valuations. As a result, the number of participants who received the second set of the questionnaire and agrees to submit some information is 71.42% more than those who received the first set of the questionnaire. Moreover, the second set of participants spends much less time in filling the questionnaire, but provides 1.78% more information on average. Integrating Symbols and Signals based on Stream Reasoning and ROS Takeshi Morita, Yu Sugawara, Ryota Nishimura, and Takahira Yamaguchi Abstract. We have developed PRactical INTElligent aPplicationS (PRINTEPS) which is a total intelligent application development platform. This paper introduces an application of PRINTEPS for detecting events by using stream reasoning and Robot Operating System (ROS), and for integrating image sensing with knowledge proces ing. Based on this platform, we demonstrate that the behaviors of a robot in a robot cafe can be modified by changing the applicable rule sets. 233 PRICAI/PRIMA/PKAW 2016 Program Book Knowledge Acquisition for Learning Analytics: Comparing teacher-derived, algorithm-derived, and Hybrid Models in the Moodle Engagement Analytics Plugin Danny Y.T. Liu, Deborah Richards, Phillip Dawson, Jean-Christophe Froissard, Amara Atif Abstract. One of the promises of big data in higher education (learning analytics) is being able to accurately identify and assist students who may not be engaging as expected. These expectations, distilled into parameters for learning analytics tools, can be determined by human teacher experts or by algorithms themselves. However, there has been little work done to compare the power of knowledge models acquired from teachers and from algorithms. In the context of an open source learning analytics tool, the Moodle Engagement Analytics Plugin, we examined the ability of teacher-derived models to accurately predict student engagement and performance, compared to models derived from algorithms, as well as hybrid models. Our preliminary findings, reported here, provided evidence for the fallibility and strength of teacher- and algorithm-derived models, respectively, and highlighted the benefits of a hybrid approach to model- and knowledge-generation for learning analytics. A human in the loop solution is therefore suggested as a possible optimal approach. Learning under Data Shift for Domain Adaptation: A Model-based Co-clustering Transfer Learning Solution Santosh Kumar, Xiaoying Gao, and Ian Welch Abstract. Data shifting in machine learning problems violates the common assumption that the training and testing samples should be drawn from the same distribution. Most of the algorithms which provide the solution for data shifting problems first try to evaluate the distributions and then reweight samples based on their distributions. Due to the difficulty of evaluating a precise distribution, conventional methods cannot achieve good classification performance. In this paper, we introduce two types of data-shift problems and propose a modelbased co-clustering transfer learning based solution which consistently deals with both scenarios of data shift. Experimental results demonstrate that our proposed method achieves better generalization and running efficiency compared to traditional methods under data or covariate shift setting. 234 PRICAI/PRIMA/PKAW 2016 Program Book Predicting the scale of trending topic diffusion among online communities Dohyeong Kim, Soyeon Caren Han, Sungyoung Lee, and Byeong Ho Kang Abstract. Online trending topics represent the most popular topics among users in certain online community, such as a country community. Trending topics in one community are different from others since the users in the community may discuss different topics from other communities. Surprisingly, almost 90% of trending topics are diffused among multiple online communities, so it shows people’s interests in a certain community can be shared to others’ in another community. The aim of this research is to predict the scale of trending topic diffusion among different online communities. The scale of diffusion represents the number of online communities that a trending topic diffuses. We proposed a diffusion scale prediction model for trending topics with the following four features, including community innovation feature, context feature, topic feature, and rank feature. We examined the proposed model with four different machine learning in predicting the scale of diffusion in Twitter Trending Topics among 8 English-speaking countries. Our model achieved the highest prediction accuracy (80.80%) with C4.5 decision tree. Quality of Thai to English Machine Translation Seamus Lyons Abstract. This paper presents the experimental results of several approaches to machine translation evaluation to determine the quality of Thai to English translation. We compare automatic metrics and human-based evaluation that includes error classification, reading comprehension and analysis from a professional translator. The research compares translation systems that are available to end users in Thailand to provide an understanding of the quality of translation in general use. Both the rate of 47.2% error words per text and the BLEU score of 0.21 indicate the difficulty of Thai to English translation. Despite a high error rate for the translations, users were able to successfully answer about 60% of the questions using the output of the machine translation systems in the reading comprehension tests. 235 PRICAI/PRIMA/PKAW 2016 Program Book Robust Modified ABC Variant (JA-ABC5b) for Solving Economic Environmental Dispatch (EED) Noorazliza Sulaiman, Junita Mohamad-Saleh, and Abdul Ghani Abro Abstract. Artificial bee colony (ABC) algorithm has been widely used in solving various optimization problems due to its simplicity and flexibility besides showing outrageous results in comparison to other optimization algorithms. Nevertheless, ABC has been found to suffer from few limitations such as slow convergence rates and premature convergence tendency. With the motivation to overcome the problem, this work proposes a modified ABC variant referred to as JA-ABC5b with the aim of robust and faster convergence. The proposed ABC variant has been compared with the standard ABC and other existing ABC variants on 27 benchmarks functions and to solve economic environmental dispatch (EED) problem. The results have shown that JAABC5b has the best performance in comparison to the standard ABC and selected existing ABC variants in terms of convergence speed and global optimum achievement besides exhibits robust performance in solving complex real-world optimization problems. Specialized Review Selection Using Topic models Anh Duc Nguyen, Nan Tian, Yue Xu, and Yuefeng Li Abstract. Online reviews and comments about a product or service are an invaluable source of information for users to assist them in making purchase decisions. In recent years, the research in review selection has attracted considerable attention. Many of the existing works attempted to identify a number of statistical features related to review text such as word count (Mudambi & Schuff, 2010) and hidden relations between these features and review quality by using supervised learning methods such as classification techniques. However, one significant drawback of these works is that they do not take the review content into consideration. A recent work has been proposed to find specialized reviews that focus on a specific feature based on similar words to the feature (Long et al., 2014). In this paper, we propose a topic model based method which selects reviews by considering both similar words and related words from a topic model such as LDA model. The conducted experiment has proven that those related words generated from LDA have a great contribution to the task of finding helpful reviews on a specified feature. 236 PRICAI/PRIMA/PKAW 2016 Program Book Stable Matching in Structured Networks Ying Ling, Tao Wan and Zengchang Qin Abstract. Stable matching studies how to pair members of two sets with the objective to achieve a matching that satisfies all participating agents based on their preferences. In this research, we consider the case of matching in a social network where agents are not fully connected. We propose the concept of D-neighbourhood associated with connective costs to investigate the matching quality in four types of well-used networks. A matching algorithm is proposed based on the classical Gale-Shapley algorithm under constraints of network topology. Through experimental studies, we find that the matching outcomes in scale-free networks yield the best average utility with least connective costs comparing to other structured networks. This research provides insights for understanding matching behavior in social networks like marriage, trade, partnership, online social and job search. Workflow interpretation via Social Networks Eui Dong Kim and Dr. Peter Busch Abstract. We sought to determine how people worked in practice, how management saw they worked and examine ‘gaps’ between these two ‘views’. In order to see potential differences, we examined workflow management through interviews with managers and a questionnaire with employees. The results were analysed through Petri Nets in a simplified form. The second unit of analysis was examining relationships between employees and therefore their knowledge flows using Social Network Analysis to illustrate work patterns staff had with one another. Through overlaying the two we gained some understanding of matches and mismatches. The study took place in three IT units of one organisation - an Australian university. The outcomes of our study comprise potential recommendations for improving work efficacy, such as re-organising work practices, or potentially changing who works with whom. 237 PRICAI/PRIMA/PKAW 2016 Program Book Fuzzy C-Means Classification of Electroencephalography (EEG) Waves for Robotic System Time Events and Control Ebrahim A. Mattar1 and Hessa J. Al-Junaid2 1College of Engineering, University of Bahrain, P.O. Box 32038, Kingdom of Bahrain [email protected] 2College of Information Technology, University of Bahrain, P.O. Box 32038, Kingdom of Bahrain [email protected] Abstract. The brain is the most complicated part of any intelligent life forms, it controls almost everything in the body. For controlling a system via a brain, there must be communication. After years of medical research, it was established that, brains communicate with origins via massive set of electrical signals (Electroencephalography (EEG)) that are periodically sent. Such (EEG) waves are sent from neurons in the brain to the ones in the spinal cord and end in nerve endings in the origins. The neurons are connected together, in addition to nerves using synapses. This is the basic structure of the nervous system that is in charge of communications between the brain and the rest of the body. The brain signals are basically electrical currents. Recently, also EEG-Based robotics systems control has received a fundamental attention by researchers world-wide. This is due to the advancement of related propping and sensing technologies for non-invective propping of the complicated, and coupled neural brains waves, in addition to the beneficial use and background gained for such BCI technologies. In particular, moving a robotic system via human brainwaves, has received a focal attention due to the advantages resulting from this technology for robotics and rehabilitations applications. One of the major issue that is needed to be looked into is related to the DECODING and PATTERNS of the resulting EEG waves for motorizing applications. There are a number of decoding methods and techniques, however, we shall will look into FUZZY C-MEANS related decoding. In this respect, the aim of this paper is to use fuzzy c-mean clustering for EEG waves, in such a way to control a robotic system using a set of detected EEG brainwaves. The EEG waves will be analysed based on fuzzy c-mean routines, in such a way to detect and define events that are of meaningful to the robotic system under control. The EEG decoding will involve a number of procedures, as this will lead to the classification routines. In addition, a fuzzy c-means classification technique will used, as this will help in building a fuzzy based rule system. For accomplishing this study, we shall rely on ready detected and measured EEG brainwaves (from well-known International Laboratories), to ensure the stability, accuracy, and the data. Subsequently, the technique will also be used for allowing the EEG waves control a robotic system. The system under control will be a robotic arm system, as such EEG will help in motorising the robotic arm in small scale moving space.

Phuket must definitely be one of the answers. A number of exciting activities can be found on this island. In the early days of regional maritime trade, the cape of Phuket was locally referred to as Jung Ceylon, while locals called it Thalang, which evolved to be the name of the main town to the north of the island. As the perfect stopover sheltering traders from monsoons, Jung Ceylon welcomed merchants from India, Persia, Arabia, Burma, China, and also Siam. During the 16th century, the island was a popular trading port for tin. In 1785, Thalang town was surrounded by Burmese troops who invaded the coastal area. It was under the leadership of Chan, the widow of the governor, and her sister, Muk, who united the local residents and successfully fought and drove the invaders out of Phuket. It took over 30 days for the defending troops of Phuket, under the command of Chan and Muk, to claim their victory. As a result of such heroic deeds, noble titles were granted to Chan and Muk as Thao Thep Kasattri and Thao Sri Soonthorn, respectively. They are still highly respected by Phuket residents even today. When the city was in a peaceful state, the development of mining was so unprecedented. Chinese businessmen and miners later migrated to Phuket and soon enjoy thriving wealth. The island’s long history has shaped the Phuket of the present with its diverse ethnic groups, culture, architectural influence, and fine cuisine. These attributes have made Phuket a complete tourist destination that offers a lot more beyond its natural heritage of sea, sand, forest, and world-renowned diving 241 PRICAI/PRIMA/PKAW 2016 Program Book sites. Sino-Portuguese architecture casts its spell delighting travellers to the city, while Phuket style of hospitality has never failed to impress visitors from all walks of life. As the most popular island destination in Thailand, Phuket has numerous options for traveling to the island and getting around once you arrive. Both domestic and international airlines service Phuket Airport with direct flights from numerous destinations in Thailand and around Asia. Once on the island, the size of Phuket makes a rental car arguably the best option, though there are various modes of transportation if you do not wish to drive. Source: http://www.tourismthailand.org Getting Around in Phuket Car Rental Service: There are numerous car rental services on Phuket. Cars or jeeps can be rented at the airport, in Phuket Town, and at most of the more popular beaches. Be aware that only Commercial First Class Insurance provides full coverage on rental cars (as opposed to limited personal or third party only insurance). Most international car rental agencies will offer this insurance (some only for those with a valid international driver’s license) while local companies may or may not. You may wish to request a copy of their insurance policy and ensure that it states “For Commercial Use”. Regardless, inspect rental vehicles prior to rental and drive with caution, particularly as traffic in Thailand can be quite confusing, especially the habit of Thai motorcycles drivers to drive on the wrong side of the road. Motorbike Rental: For around 150 to 300 baht per day you can hire your own 100-150cc motorbike, which will typically require you to leave your passport as a deposit. Be sure to inspect bikes prior to rental and drive with extreme caution as rental motorbikes are not normally insured and accidents are frequent. Helmets are required by Thai law. Motorcycles can be rented from rental agencies located on Rasada Road or from different operators at various beaches.Motorcycle taxis: It costs approximately 20 baht / person / trip to travel via motorbike taxi around Phuket Town. Songtaew and Tuk-Tuk: Songtaews are operated along Ranong Road in Phuket Town to various destinations including most beaches. The cost ranges from 20 baht to 25 baht / person / trip. Normally the service is provided from 7.00 a.m. until 5.00 p.m. Tuk-Tuks can be chartered for travel between the beaches and Phuket Town or between different beaches; however, rates are negotiable and will cost at least 200 baht to Patong Beach, 230 baht to Karon and Kata Beaches and 300 baht to Nai Han and Kamala Beaches. Within Phuket Town, Tuk-Tuks should cost 20 baht for short distances. Taxi Meter: For a Taxi Meter in Phuket, Visitors can call 076 232157-8 to get a metered taxi that will take them anywhere on Phuket. The metered fare will include a 20 baht surcharge. Boat 242 PRICAI/PRIMA/PKAW 2016 Program Book to islands nearby Phuket: Boats to nearby islands can be found at the following ports: Rawai Beach: An old local port, it is from here that long-tail boats depart for nearby islands such as Koh He, Koh Racha Yai, Koh Mai Thon, Koh Lon, etc. The chartered price depends on the distance. Ao Chalong: The largest port of Phuket servicing all kinds of boats, including cruisers of tour companies that organize package tours to other islands. Ao Makham: Located near Phanwa Cape, this port is only for cruisers and container ships. Boat Lagoon Port (Ao Sapam): This port is for traveling boats of tour companies. Weather Phuket has a tropical monsoonal climate. It’s warm all year round, but the two periods of April-May and September-October are the hottest. The September-October period is also the wettest due to the southwest monsoon. Phuket is blessed by being in a temperate zone. Even though typhoons and tropical storms occasionally batter Hong Kong and the Philippines, Phuket enjoys mild weather and while the heavier rains in September and October can disrupt things a little, it’s rare that the island has several consecutive days of heavy rain. The best time to visit Phuket is during the cool NE monsoon season, from December through March, when it isn’t so humid, and the cool breezes keep things comfortable. The average temperature is around 75F to 89F (24C to 32C). Note that lately, as almost everywhere in the world, weather is unpredictable.
