Abstract

The Korean Brain Neuroinformatics Research Program enters its 3rd phase starting July 2004, for 4 years, which is regarded as the final phase of Korean brain national research program, initiated in November 1998 for 10 years. It has two goals, i.e., to understand information processing mechanisms in biological brains and to develop intelligent machines with human-like functions based on the mechanism. In the 3rd phase we are developing an integrated hardware and software platform for brain-like intelligent systems, which combine all the technologies developed for the brain functions in the second phase. With 2 microphones, 2 cameras (or retina chips), and one speaker, the Artificial Brain models a human head, and has the functions of vision, auditory, cognition, and behavior. Also, with this platform, we plan to develop a testbed application, i.e., "artificial secretary," alias OfficeMate, which is expected to reduce the working time of human secretary by half. In this talk the goals and current status of the Korean Brain Neuroinformatics Research Program will be presented with some introduction to recent developments. In the second part of the talk I will show some examples of how small hints from cognitive neuroscience can contribute to the engineering models of human brain functions. This part will mainly focus on the modeling of human auditory pathway for feature extraction, binaural processing, and top-down attention.

Biography

Dr. Soo-Young Lee received his B.S., M.S., and Ph.D. degrees from Seoul National University in 1975, Korea Advanced Institute of Science in 1977, and Polytechnic Institute of New York in 1984, respectively. He is currently a professor at the Department of Electrical Engineering, the Department of BioSystems, and the Department of Electrical Engineering and Computer Science, at KAIST. Since 1997, he is directing the Brain Science Research Center, which is the main research organization for the Korean Brain Neuroinformatics Research Program, sponsored by the Korean Ministry of Science and Technology. He served as chair on numerous international conferences in the area of neural networks, is on the editorial board of Neural Processing Letters, and is the founding editor-in-chief of a new rapid, double-blind review journal Neural Information Processing-Letters and Reviews. His service has been recognized by leadership awards such as the Presidential Award from the International Neural Network Society in 1994 and in 2001. His research interests include models of the auditory pathway, developmental models of multi-modal man-machine interactions, and top-down selective attention for overlapping pattern recognition. He employs mathematical techniques and neuromorphic chips to model neural systems, and apply the understanding in real-world applications. He is currently extending his research into brain-computer interfaces using simultaneous fMRI and EEG measurements.
