This special issue of the journal is devoted to Fuzzy Systems and their Applications. Today’s fuzzy technology is like a mighty dragon: every year, every day, new applications appear that are more and more helpful in our peaceful life. One of the main objectives of the Second International Vietnam-Japan Symposium on Fuzzy Systems and Applications (VJFUZZY’2001) is to help this powerful technology to achieve even more. VJFUZZY’2001 was held in Hanoi, Vietnam on December 7-8, 2001. In VJFUZZY’2001, there was a wide spectrum of fuzzy research and applications, including sessions: “Fuzzy Mathematics”, “Fuzzy Image/Signal Processing and Pattern recognition”, “Fuzzy Optimization/Programming”, “Fuzzy Data Analysis and its applications”, “Towards Combining Fuzzy, probability and other techniques”, “Learning, Neural Networks and Applications”, “Fuzzy/Intelligent Control”, “Natural Language Processing” etc. Many very interesting results were presented at the symposium. Among these various and excellent papers, this special issue offers a selection of nine papers that contribute to advances of computational intelligence in various aspects. The topics that the selected papers deal with are fuzzy relation with threshold, nonlinear optimization with convex polyhedral objective function, reinforcement learning of fuzzy control rules, learning of probabilistic causal models, data querying in fuzzy relational database, case-based reasoning in medial diagnosis, analysis of human brain activities for fuzzy and crisp calculations, fuzzy robust control of a decentralized system and image processing using fuzzy mathematical morphology. As editors of this special issue, we would like to express our thanks to all of the contributors for their interesting results, the anonymous referees for their thankless job and the Editorial Board of JACI, especially Prof. Kaoru Hirora, for the enthusiastic hospitality with which JACI agreed to have this special issue. Finally, we want to thank Prof. Hung T Nguyen and Prof. Michio Sugeno – for their supports to VJFUZZY’2001. Without their help, the VJFUZZY’2001 and then this special issue would not be impossible.
