JACK KEIL WOLF LECTURE SERIES

ABSTRACT:  The presentation starts by demonstrating in a descriptive way the origin of information theory in Shannon’s 1948 monumental work, and pointing some interdisciplinary aspects within general areas of electrical engineering and beyond. We discuss a change of paradigms in information theory from being a pure mathematical theory of communications to a theory with widescope direct practical implications and applications. To demonstrate the rich aspects of the problems considered and their implications as well as some inter disciplinary connections, we focus on a simple matrix based linear additive Gaussian model. We elaborate on the information-estimation intimate connection, mentioning its impact on non-linear filtering and on recent views of efficient coding in single and multi-terminal channels. Possible extensions to general channels and a short outlook conclude the presentation.

BIOGRAPHY: Shlomo Shamai (Shitz) received the B.Sc., M.Sc., and Ph.D. degrees in electrical engineering from the Technion—Israel Institute of Technology, in 1975, 1981 and 1986 respectively. Since 1986 he is with the Department of Electrical Engineering, Technion-Israel Institute of Technology, where he is now a Technion Distinguished Professor, and holds the William Fondiller Professor of Telecommunications chair.
