Talk Title: Graph Signal Processing in the Spectral Domain: Filter Design, Denoising, and Applications
Abstract: Graph signal processing (GSP) is an emerging field of signal and information processing. It aims to extract useful information from complex structured data. There are many potential application areas, e.g., sensor networks including IoT, smart grid, biomedical engineering, machine learning, computer vision/graphics, pattern recognition, bioinformatics, and geographic information systems. First, fundamentals of graph signal processing are briefly introduced in this talk, then some recent works on GSP in the graph spectral (graph Fourier) domain, which include wavelet/filter bank design, graph signal denoising, sensor placement in the GSP perspective, and EEG signal classification, will be presented.
Biography: Yuichi Tanaka received the B.E., M.E. and Ph.D. degrees in electrical engineering from Keio University, Yokohama, Japan, in 2003, 2005 and 2007, respectively. He was a Postdoctoral Scholar at Keio University, Yokohama, Japan, from 2007 to 2008, and supported by the Japan Society for the Promotion of Science (JSPS). From 2006 to 2008, he was also a visiting scholar at the University of California, San Diego (VideoProcessing Group supervised by Prof. T. Q. Nguyen). From 2008 to 2012, he was an Assistant Professor in the Department of Information Science, Utsunomiya University, Tochigi, Japan. Since 2012, he has been an Associate Professor in Graduate School of BASE, Tokyo University of Agriculture and Technology, Tokyo, Japan. His current research interests are in the field of multidimensional signal processing which includes: graph signal processing, image and video processing with computer vision techniques, distributed video coding, objective quality metric, and effective spatial-frequency transform design. Dr. Tanaka has been an Associate Editor of IEICE Trans. Fundamentals since 2013. Currently he is an elected member of the APSIPA Image, Video and Multimedia Technical Committee. He was a recipient of the Yasujiro Niwa Outstanding Paper Award in 2010, the TELECOM System Technology Award in 2011, and Ando Incentive Prize for the Study of Electronics in 2015. He also received APSIPA ASC 2014 Best Paper Award.
