Information theory is based on probabilistic modeling of the sources and channels which define the information quantities like entropy and capacity and the associated coding schemes. However, in reality, these models are unknown and may even be nonexistent. Yet, practical communication systems work under uncertainty and varying conditions. The key capability to combat uncertainty is termed “universality”. Universal schemes adapt, learn, work, and can even be optimal, no matter what the model is. The universality concept will be presented in several basic communication problems:

  • Lossless source coding and the associated problem of universal prediction and learning;
  • Channel decoding and channel coding (which requires at least some feedback);
  • Joint source channel coding – a universal “hybrid analog-digital” solution recently received the scientific and engineering award of the academy of motion pictures (Oscar)

Meir Feder received the B.Sc and M.Sc degrees in Electrical Engineering in 1980 and 1984 from Tel-Aviv University and the Sc.D degree in Electrical Engineering and Ocean Engineering in 1987 from the Massachusetts Institute of Technology (MIT) and the Woods Hole Oceanographic Institution (WHOI). After being a Research Associate and a Lecturer in MIT, he joined the School of Electrical Engineering, Tel-Aviv University, where he is now a Chaired Professor and the head of the newly established Tel-Aviv university center for Artificial intelligence and Data science (TAD). He is also a Visiting Professor with the Department of EECS, MIT.

Parallel to his academic career, he is closely involved with the high-tech industry. He founded 5 companies, among them are Peach Networks that developed an interactive TV solution (Acq: MSFT) and Amimon that provided the highest quality, robust and no delay wireless high-definition A/V connectivity (Acq:LON.VTC). Recently, with his renewed interest in machine learning and AI, he cofounded Run:ai, a virtualization, orchestration, and acceleration platform for AI infrastructure. He is also an active angel investor and serves on the board/advisory board of several US and Israeli companies.

Prof. Feder received several academic and professional awards including the IEEE Information Theory Society best paper award for his work

on universal prediction, the “creative thinking” award of the Israeli Defense Forces, and the Research Prize of the Israeli Electronic Industry, awarded by the President of Israel. For the development of Amimon’s chip-set, that uses a unique MIMO implementation of joint source-channel coding for wireless video transmission he received the 2020 Scientific and Engineering Award of the Academy of Motion Picture Arts and Sciences.

With Purpose: Information Flow in the Era of Hyperspecialization

July 15, 01:00 - 02:00


We argue that, as the amount of data that we need to transport, store and protect expands, there is a growing trend to (hyper-)specialize the techniques for information flow, compression and security, by tailoring them to the task purpose. We will present examples of this trend in our work that include pliable index coding, distortion security, task-aware compression, and community aware group testing.


Christina Fragouli is a Professor in the Electrical and Computer Engineering Department at UCLA and an IEEE fellow. She received the B.S. degree in Electrical Engineering from the National Technical University of Athens, Athens, Greece, and the M.Sc. and Ph.D. degrees in Electrical Engineering from the University of California, Los Angeles. She has worked at the Information Sciences Center, AT&T Labs, Florham Park New Jersey, and the National University of Athens. She also visited Bell Laboratories, Murray Hill, NJ, and DIMACS, Rutgers University. She was on the faculty at the School of Computer and Communication Sciences, EPFL, Switzerland, where she was an Associate Professor before she joined UCLA, where she directs the Laboratory for Algorithms for Networked Information (ARNI).

She has served as an Information Theory Society Distinguished Lecturer, and has received recognitions for her work, including several paper awards. She has served as Associate Editor for IEEE Transactions on Information Theory, IEEE Transactions on Communications, and IEEE Transactions on Mobile Computing among others. She has also served in several IEEE committees and organized IEEE conferences. Her research interests are in the intersection of coding theory and algorithms, with applications in network information flow, network security and privacy, wireless networks and bioinformatics.

Benign Overfitting

July 17, 01:00 - 02:00


Deep learning methodology has revealed some major surprises from the perspective of statistical complexity: even without any explicit effort to control model complexity, these methods find prediction rules that give a near-perfect fit to noisy training data and yet exhibit excellent prediction performance in practice. In this talk, we survey some recent work on this phenomenon of ‘benign overfitting.’ In the setting of linear prediction, we give a characterization of linear regression problems for which the minimum norm interpolating prediction rule has near-optimal prediction accuracy. The characterization shows that overparameterization is essential: the number of directions in parameter space that are unimportant for prediction must significantly exceed the sample size. We discuss implications for deep networks and for robustness to adversarial examples, and we describe extensions to ridge regression and barriers to analyzing benign overfitting via model-dependent generalization bounds.


Peter Bartlett is a professor in the Department of Electrical Engineering and Computer Sciences and the Department of Statistics at the University of California at Berkeley, Associate Director of the Simons Institute for the Theory of Computing, Director of the Foundations of Data Science Institute, and Director of the Collaboration on the Theoretical Foundations of Deep Learning.

Broadcast Channels - What’s New


This talk aims to present a (biased) summary of recent results in broadcast channels which owe heavily to novel techniques in evaluations of achievable regions and outer bounds. Additionally, the talk will also identify some elementary settings for which either the current techniques are insufficient or for which there are tantalising conjectures; hoping that these will inspire future research in this area.
