Although knowledge discovery and data mining techniques have been successfully employed to various real-world applications, the classification of an imbalanced dataset remains challenging. This challenge has attracted attention from both academia and industry. Classification analysis is one of core research topics in pattern recognition field. According to the distribution of samples, algorithms like artificial network (ANN) and support vector machine (SVM) have been proposed to perform binary classification. But these traditional classification algorithms hardly work well for imbalanced dataset. This talk illustrates recent results in imbalanced data classification.
Dr. Junzo Watada received his B.Sc. and M.Sc. degrees in electrical engineering from Osaka City University, Japan, and Dr. of Eng. degree through the research on fuzzy multivariate analysis from Osaka Prefecture University, Japan.
He is a Professor of Knowledge Engineering, Soft Computing and Management Engineering at the Graduate School of Information, Production & Systems, Waseda University since 2003, after a professor of Human Informatics and Knowledge Engineering, at the School of Industrial Engineering, the Osaka Institute of Technology, Japan. Also Dr. Watada gave as a fucclty lectures on Management Information Systems for 8 years at Faculty of Business Administration, Ryukoku University at Kyoto. Before moving to Academia, he was with Fujitsu Co. Ltd. as a senior systems engineer for 7 years.
III Research Interests
His research interests includes business decision making and management of technology and engineering as well as fuzzy system methodologies, automata theory, text and web mining, decision support systems and experts systems, DNA computing, data analysis, etc.. Recently he works actively on meta heuristics, and human tracking, as well as financial engineering He published more than 600 academic papers of journals and international proceedings.
IV Academic Contribution
He was the President of Bio-Medical Fuzzy Systems Association (2001-2003). He was the Vice President of Japan Society for Fuzzy Theory and Systems for two years (1993-1995) and was a board committee of Japan Society for Fuzzy Theory and Systems, and also serve as an advisory board member for several international and domestic societies and also an editorial board member for international and domestic journals including ICIC express letters.
