The USC Viterbi School has recently announced Professor Abbas El Gamal of Stanford University will present the 2014 Andrew J. Viterbi Distinguished Lecture in Communication. The 12th annual lecture entitled “Common Information” will be given on Thursday, April 17, 2014 at 4:00 PM at the University of Southern California in the Seeley Wintersmith Mudd Memorial Hall of Philosophy (MHP) room 101. A reception will precede the lecture at 3:00 PM.
USC’s Viterbi School of Engineering has provided the following abstract for the talk:
Entropy, introduced by Shannon in 1948, arises naturally as a universal measure of information in single-source compression, randomness extraction, and random number generation. In distributed systems, such as communication networks, multiprocessors, distributed storage, and sensor networks, there are multiple correlated sources to be processed jointly. The information that is common between these sources can be utilized, for example, to reduce the amount of communication needed for compression, computing, simulation, and secret key generation. My talk will focus on the question of how such common information should be measured. While our understanding of common information is far from complete, I will aim to demonstrate the richness of this question through the lens of network information theory. I will show that, depending on the distributed information processing task considered, there can be several well-motivated measures of common information. Along the way, I will present some of the key models, ideas, and tools of information theory, which invite further investigation into this intriguing subject. Some parts of this talk are based on recent joint work with Gowtham Kumar and Cheuk Ting Li and on discussions with Young-Han Kim.
