Varshney Plenary Speaker at 40th Anniversary of IEEE Conference
May 13, 2015
Professor Pramod K. Varshney was the plenary speaker at the 40th IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP) 2015 in April 2015.
On its 40th anniversary, ICASSP is the world’s largest and most comprehensive technical conference focused on signal processing and its applications. The 2015 conference featured world-class presentations by internationally renowned speakers, cutting-edge session topics and provide a fantastic opportunity to network with like-minded professionals from around the world.
Professor Varshney's Abstract
Noise-Enhanced Information Systems
Denoising Noisy Signals with Noise
Noise, traditionally defined as an unwanted signal, has been shown to play an important constructive role in many information processing systems. Performance enhancement via noise has been observed and employed in many physical, biological, and engineered systems. The concept of stochastic facilitation (SF) has been found critical for certain biological information functions such as detection of weak, subthreshold stimuli or suprathreshold signals through both experimental verification and analytical model simulations. In this talk, we present a systematic noise-enhanced information processing framework to analyze and optimize the performance of engineered systems. System performance is evaluated not only in terms of signal-to-noise ratio but also in terms of other more relevant metrics such as probability of error for signal detection or mean square error for parameter estimation. As an important new instance of SF, we also discuss the constructive effect of noise in associative memory recall. Potential enhancement of image processing systems through the addition of noise is discussed with important applications in biomedical image enhancement, image denoising, and classification. Some avenues for further research are outlined.
About Professor Varshney
Pramod K. Varshney was born in Allahabad, India, on July 1, 1952. He received the B.S. degree in electrical engineering and computer science (with highest honors), and the M.S. and Ph.D. degrees in electrical engineering from the University of Illinois at Urbana-Champaign in 1972, 1974, and 1976 respectively. Since 1976 he has been with Syracuse University, Syracuse, NY where he is currently a Distinguished Professor of Electrical Engineering and Computer Science and the Director of CASE: Center for Advanced Systems and Engineering. He served as the Associate Chair of the department during 1993-96. He is also an Adjunct Professor of Radiology at Upstate Medical University in Syracuse, NY. His current research interests are in distributed sensor networks and data fusion, detection and estimation theory, wireless communications, physical layer security and image processing, radar. He has published extensively. He is the author of Distributed Detection and Data Fusion, published by Springer-Verlag in 1997.
While at the University of Illinois, Dr. Varshney was a James Scholar, a Bronze Tablet Senior, and a Fellow. He is a member of Tau Beta Pi and is the recipient of the 1981 ASEE Dow Outstanding Young Faculty Award. He was elected to the grade of Fellow of the IEEE in 1997 for his contributions in the area of distributed detection and data fusion. In 2000, he received the Third Millennium Medal from the IEEE and Chancellor’s Citation for exceptional academic achievement at Syracuse University. He is the recipient of the IEEE 2012 Judith A. Resnik Award. He was awarded the degree of Doctor of Engineering honoris causa by Drexel University in 2014. He is on the editorial boards of Journal on Advances in Information Fusion and IEEE SP Magazine. He was the President of International Society of Information Fusion during 2001
