This volume contains the proceedings of the Fifth International Joint Conference on Computational Intelligence (IJCCI 2013), which was sponsored by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC) and held in Vilamoura, Algarve, Portugal. IJCCI was organized in cooperation with the AAAI - Association for the Advancement of Artificial Intelligence, APNNA - Asia Pacific Neural Network Assembly and ACM SIGART - ACM Special Interest Group on Artificial Intelligence. Since its first edition in 2009, the purpose of the International Joint Conference on Computational Intelligence (IJCCI) is to bring together researchers, engineers and practitioners in Computational Intelligence and issued technologies. The aim is to provide major forums for scientists, engineers and practitioners interested in the development, analysis, design and application of the aforementioned areas and issued techniques to all fields of human activity. Concerned
especially with areas of fuzzy computation, evolutionary computation and neural computation, IJCCI is composed of three co-located conferences, each one specialized in one of the aforementioned - knowledge areas. Namely: - International Conference on Evolutionary Computation Theory and Applications (ECTA) - International Conference on Fuzzy Computation Theory and Applications (FCTA) - International Conference on Neural Computation Theory and Applications (NCTA) In ECTA, modeling and implementation of bio-inspired systems namely on the evolutionary premises, both theoretically and in a broad range of application fields, is the central scope. Considered as a subfield of computational intelligence focused on combinatorial optimization problems, evolutionary computation is associated with systems that use computational models of evolutionary processes as the key elements in design and implementation, i.e. computational techniques which are inspired by the evolution of biological life in the natural world. A number of evolutionary computational models have been proposed, including evolutionary algorithms, genetic algorithms, evolution strategies, evolutionary programming, swarm optimization and artificial life. In FCTA, modeling and implementation of fuzzy systems, in a broad range of fields, is the main concern. Fuzzy computation encompasses the theory and application of fuzzy sets and fuzzy logic to the solution of information processing, system analysis and decision problems. Bolstered by information technology developments, the extraordinary growth of fuzzy computation in recent years has led to major applications in fields ranging from medical diagnosis and automated learning to image understanding and systems control. NCTA is focused on modeling and implementation of artificial neural networks computing architectures. Neural computation and artificial neural networks have seen a continuous explosion of interest in recent years, and are being successfully applied across an impressive range of problem domains, in areas as diverse as finance, medicine, engineering, geology and physics, in problems of prediction, classification decision or control. Several architectures, learning strategies and algorithms have been introduced in this highly dynamic field in the last couple of decades. The joint conference, IJCCI received 111 paper submissions from 30 countries, which demonstrates the global dimension of this conference. 24 papers were published as full papers (21,6% of submissions) and 29 were accepted for short presentation (26% of submissions). Moreover, 13 were accepted for poster presentation. These ratios denote a high level of quality which we aim to continue reinforcing in the next edition of this conference. The high quality of the papers received imposed difficult choices in the review process. To evaluate each submission, a double blind paper evaluation method was used: each paper was reviewed by at least two experts from the independent international Program Committee, in a double-blind review process, and most papers had three reviews or more. Moreover, the conferences also featured a number of keynote lectures delivered by internationally well known experts, namely: Kevin Warwick (University of Reading, United Kingdom), Leslie Smith (University of Stirling, United Kingdom), Juan J. Merelo (Universidad de Granada, Spain), Eyke Hüllermeier (Philipps University of Marburg, Germany), Belur V. Dasarathy (Information Fusion, United States), Alexandre Castro-Caldas (Portuguese Catholic University, Portugal). The meeting was also complemented with two special sessions, the Special Session on Computational Models based on Soft Computing and its Applications – SCA (chaired by José M. Cadenas, M. Carmen Garrido and Raquel Martínez) and the Special Session on Challenges in Neuroengineering - SSCN (chaired by Francois-Benoit Vialatte, Jordi Solé-Casals and Justin Dauwels). The best contributions to the conference and the best student submissions were distinguished with awards based on the best combined marks of paper reviewing, as assessed by the Program Committee, and the quality of the presentation, as assessed by session chairs at the conference venue. All presented papers will be submitted for indexation by Thomson Reuters Conference Proceedings Citation Index (ISI), INSPEC, DBLP, EI (Elsevier Index) and Scopus, as well as being made available at the SCITEPRESS Digital Library. Additionally, a short list of presented papers will be selected to be expanded into a forthcoming book of IJCCI Selected Papers to be published by Springer-Verlag. Also, a post-conference special issue of the Springer's LNCS TCCI Journal is planned for publication of an extended version of a restricted number of original high quality papers presented during the IJCCI 2013. Additionally, a special issue of the Elsevier Journal of Information Fusion on "Information Fusion in Multi-dimensional Knowledge Discovery and Computational Intelligence" has been planned. Building an interesting and successful program for the conference required the dedicated effort of many people. We would like to express our thanks, first of all, to all authors including those whose papers were not included in the program. We would also like to express our gratitude to all members of the Program Committee and auxiliary reviewers, who helped us with their expertise and valuable time. Furthermore, we thank the invited speakers for their invaluable contribution and for taking the time to synthesize and prepare their talks. Moreover, we thank the special session chairs whose contribution to the diversity of the program was decisive. Finally, we gratefully acknowledge the professional support of the INSTICC team for all organizational processes.
