3 Welcome from General Chair It is my pleasure to welcome you to Curitiba for the 2012 Brazilian Conference on Intelligent System, BRACIS We very much hope you enjoy this city and all it has to offer. BRACIS 2012 encompasses the following important scientific events: XXI Brazilian Symposium on Artificial Intelligence - SBIA XII Brazilian Symposium on Neural Network - SBRN IX Encontro de Inteligência Artificial - ENIA And some co-allocated events: VIII Best MSc Dissertation/PhD Thesis Contest in Artificial Intelligence - CTDIA IV International Workshop on Web and Text Intelligence - WTI III Brazilian Workshop on Social Simulation - BWSS All these events aim to present the state-of-the-art research on Artificial Intelligence, Neural Networks (NNs) and other models of Computational Intelligence (CI) such as Fuzzy Logic and Evolutionary Computing from Brazil, Latin-American and other parts of the world. One of highlights of BRACIS 2012 is the free tutorials and workshops held during the first two days of the conference. Thanks to Roseli Romero and Alneu Lopes for chairing the tutorials and Fabricio Enembreck, the workshops. I couldn t have planned BRACIS 2012 without the generous time commitment of all local chairs. Finally, I would like to thank you, authors, presenters, reviewers, and all other attendees. Be kindly welcome to BRACIS 2012.

6 Invited Speakers Room Gregor Mendel Auditorium Title: Machine Learning and Computational Sustainability Mon 22/10 8:30 am chair: Prof a. Dr a. Ana Lorena Thomas G. Dietterich Computational Sustainability is the study of computer science methods for solving sustainability challenges. These challenges include sustainable cities, sustainable development, energy, transportation, ecological science, and ecosystem management. In this talk, I will focus on research opportunities in ecological science and ecosystem management and describe some of the work in my lab on these problems. This includes (a) automated data cleaning and anomaly detection in sensor data streams, (b) species distribution modeling including modeling of bird migration from citizen science data, and (c) design of optimal policies for managing wildfires and invasive species. The novel machine learning challenges include flexible anomaly detection for multiple data streams, explicit models of sampling bias and measurement processes, combining probabilistic graphical models with non-parametric learning methods, collective graphical models for reasoning with count data, and optimization of complex spatiotemporal Markov decision processes. Title: Individual and Collective Rationality in Complex Systems Mon 22/10 16:30 pm chair: Prof. Dr. Jaime Sichman Alan Kirman This talk will analyse the emergence of collective behaviour which has a certain rationality from the point of view of the aggregate but which does not correspond to that of the individual. In economics it has long been recognised that, as a result of externalities behaviour that is rational from the point of view of the individual may lead to collective disasters as in the case of the Tragedy of the Commons. However, even more interesting are the cases where individuals who interact locally and have only limited information can together produce outcomes which have regularities which could not have been predicted from the individual motives. These may be beneficial but may also, as a result of contagion, lead the system to sudden
7 collapse. Modelling this sort of phenomena usually involves starting with a formal analysis of a very simple case and then simulating a more complex and realistic system to see whether the results for the simple case still hold in the more general case. I will illustrate this with a number of examples, from some observations about the analogies with social insects, and ant and bees in particular, to recent work on the extension of the Schelling model of segregation. In the latter we include preferences for neighborhood income as well as racial composition and introduce a housing market. We analyzed segregation in terms of both race and income and the relation between house prices and these factors. I will also discuss a model of the market for mortgage backed securities and show how the rational reactions of a few individuals to a small change in the probability of default on the underlying assets can lead to a collapse in the price of the assets. In each case the self-organization of a complex adaptive system produces aggregate results which could not have been predicted from the analysis of a representative agent. Title: Computational Models of Dialogical Argumentation Tue 23/10-8:30 am Anthony Hunter Computational models of dialogical argumentation aim to reflect how humans use and resolve conflicting information, opinions, beliefs, etc. by exchanging and analyzing arguments. This may be as part of a wider process such as decision making, sense making, or negotiation. In these formal models, a dialogue between two or more agents is normally made up of a set of communicative acts, called moves, a set of rules that state which moves are legal to make at any point in a dialogue (the protocol), and a set of rules that define the effect of making a move. In addition, each agent may have a private strategy that specifies which of the allowed moves it should do in the current state of the dialogue given its goals. In this talk, we will consider some of the main approaches to modeling dialogical argumentation, and identify some of the many research questions that have been identified.
8 Title: Data Structures for Efficient Inference and Optimization in Expressive Continuous Domains Tue 23/10 16:30 pm Scott Sanner To date, our ability to perform exact closed-form inference or optimization with continuous variables is largely limited to special well-behaved cases. This talk argues that with an appropriate representation and data structure, we can vastly expand the class of models for which we can perform exact, closed-form inference. This enables novel solutions to many problems of interest in AI, machine learning, operations research and beyond, some of which have been unsolved for 50+years. This talk is in two parts. In the first part, I introduce an extension of the algebraic decision diagram (ADD) to continuous variables -- termed the extended ADD (XADD) -- to represent arbitrary piecewise functions (nb, arbitrary pieces, not just hyper-rectangular) over discrete and continuous variables and show how to define and efficiently compute elementary arithmetic operations, integrals, and maximization for various restrictions of these functions. In the second part, I briefly cover a wide range of novel applications where the XADD may be applied: (a) exact inference in expressive discrete and continuous variable graphical models, (b) factored, parameterized linear and quadratic optimization (a generalization of LP and QP solving), (c) exact solutions to piecewise convex functions that enable a number of novel applications in machine learning, and (d) exact solutions to continuous state, action, and observation sequential decision-making problems -- which includes closed-form solutions to previously unsolved problems in operations research. This is joint work with Zahra Zamani & Ehsan Abbasnejad (Australian National University), Karina Valdivia Delgado & Leliane Nunes de Barros (University of Sao Paulo), and Simon Fang (M.I.T.).
9 Title: Evolutionary Computation: Where We are and Where We're Headed Wed 24/10 8:30 pm Prof a. Dr a. Ana Lorena The field of evolutionary computation has experienced a significant growth of interest and activity in the past decade. This has resulted in fresh perspectives and a flurry of new results in both theory and applications. This presentation will summarize the recent progress and characterize some of the remaining unresolved research issues. Kenneth A. De Jong Leandro de Castro Title: Natural Computing: The Grand Challenges and Two Case Studies Wed 24/10 16:30 pm Although the origins of Natural Computing (NC) can be traced back to the early days of Computer Science in the 1940s, it only became a formal discipline around the year Since then, there has been a flood of research papers on the use of Nature to inspire the design of novel algorithms. Now, it is felt that the field faces some Grand Challenges so as to progress and mature. A new perspective of the field has emerged, broadening its scope, and three Grand Challenges have been proposed: to transform Natural Computing into a transdisciplinary science; to harness information processing in natural systems; and to formally and consistently engineer Natural Computing approaches. This talk introduces and discusses the Grand Challenges in Natural Computing Research and then, for showing the pragmatism and usefulness of NC, follows with the presentation of two real-world applications of Natural Computing, one for Social Media and another in e-commerce.
