Title: Fuzzy Set Theory in Information Technology
ABSTRACT
Fuzzy set theory introduced by Lotfi Zadeh in 1965 is an extension of the classical set. It is a way to understand or explain uncertainty occurring in everyday life. Since then there are many theories and applications developed based on Fuzzy set theory. One of the areas that Fuzzy set theory has an impact on is the area of information technology, especially, data mining. One of important parts in data mining is classification or sometimes called decision making. Fuzzy inference system has been used as a decision making tool in several applications including medical image processing. In particular, it is used as a classifier in microcalcification detection in Mammogram. Recently, there is several extension of Fuzzy set theory including interval Type-2 fuzzy set theory. One of the major developments of the interval Type-2 fuzzy set theory is interval Type-2 fuzzy logic, an extension of fuzzy inference system. It is applied into medical image processing as well. There is also another popular area in Fuzzy set Theory, i.e., a theory on fuzzy vector manipulation. Many research groups have been working on developing a theory of function manipulation. In particular, a theory of how the function will perform if the function inputs are fuzzy vectors not vectors of number. The major area in this case is developing a classifier with fuzzy vectors as inputs and output(s). In this talk, these classifiers and their real applications such as an application in communication assessment will be presented as well. Another area of fuzzy vector manipulation is an area of information fusion when input information is not numbers but fuzzy numbers. This talk will also show the proposed information fusion applied in a military application.
Short Bio
Sansanee Auephanwiriyakul (S98M01) was born in Chiang Mai, Thailand, in 1971. She received the B.Eng. (Hons.) degree in electrical engineering from the Chiang Mai University, Thailand (1993), and the M.S. degree in electrical and computer engineering and Ph.D. degree in computer engineering and computer science, both from the University of Missouri, Columbia, in 1996, and 2000, respectively. She worked as a Postdoctoral Fellow at the Computational Intelligence Laboratory, University of Missouri, Columbia, on clustering techniques for humanitarian land mine detection. She is currently an Assistant Professor in the Department of Computer Engineering, Chiang Mai University, Thailand. Her research interests include neural networks, fuzzy set theory, linguistic algorithms, pattern recognition, image processing, computer vision and medical image processing.
Dr. Auephanwiriyakul is a senior member of the Institute of Electrical and Electronics Engineers (IEEE). She is an Associate Editor of the IEEE Transactions on Fuzzy System, and is an Editorial Board of the Neural Computing and Applications and an Editorial Board of the Engineering Journal, Chiang Mai. She was a Guest Editor of the Journal of Advanced Computational Intelligence and Intelligent Informatics in 2004. She was a Technical Program Chair, Organizing Committee in several major conferences including the IEEE International Conference Fuzzy Systems. She is also a member of two important IEEE organizations, i.e., Fuzzy System Technical Committee IEEE Computational Intelligence Society and Bioinformatics and Bioengineering Technical Committee IEEE Computational Society. As a part of these committee members, she has to promote the research, development, education, and understanding of the technology, including the creation of the theory and models as well as their applications. She is a member of IEEE P1855 Workgroup for Fuzzy Markup Language Standardization as well. This workgroup is trying to set up a standard and usability of the language in more practical way.
As a role of administrator, Dr. Auephanwiriyakul has worked in promoting research in the Chiang Mai University as a director of Research Administration Center (2010 2012), or a director of Biomedical engineering (2007 2010) and now a Computer Engineering Department Head (2013 ). As a role of researcher, she has written many conference papers that have been published in several major conferences, e.g., the IEEE International Conference Fuzzy Systems and journal papers published in several major journals including IEEE Transactions on Biomedical Engineering. She wrote several textbooks in Thai including Digital Image Processing, as well.
