Preface

The 2012 Brazilian Symposium on Neural Networks (SBRN), which is sponsored by the Brazilian Computer Society (SBC). SBRN is the leading conference in Brazil dedicated to Neural Networks and other models of Computational Intelligence (CI), including Fuzzy Logic, Evolutionary Computing and Machine Learning, and various soft computing techniques. The conference is focused on original theories and novel applications dealing mainly with the use and analysis of CI techniques. SBRN is an international conference with an international program committee, which includes well??established researchers from Brazil and overseas. The papers have been written in English and are published by the Conference Publishing Services (CPS), a division of the IEEE Computer Society press. The final program has 11 Technical Sessions organized around specific topics and four preconference tutorials of established researchers. The papers submitted to the symposium represented a broad range of research developed in Brazil and other countries. We received 79 submissions and after a rigorous reviewing process, 42 papers were accepted to be orally presented. All papers were reviewed by, at least, two independent specialized referees.
