Title: Joint Learning and Optimization for Robust Channel Coding and Collaborative Learning

Abstract: Adversarial feedback channel coding is a fundamental problem in information theory that has remained unsolved for almost five decades. It involves designing codes that can reliably transfer information over a noisy channel with an active adversary who can tamper with the feedback. In this talk, we will present a novel approach to adversarial feedback coding using deep learning. We will show how deep learning can overcome the limitations of conventional feedback coding and achieve unprecedented levels of reliability and scalability. We will show how our codes can solve hard problems in channel coding such as short block length reliability.
We will also propose a new model, called the Kolmogorov Model
(KM), for learning and fusing compressed interference information in wireless networks. Interference is a major source of performance degradation and security risk in wireless networks. KM can interpret, predict, and classify interference signals and enable distributed learning. We will explain how to optimize KM using dual optimization and approximation algorithms. We will also present a novel differential privacy mechanism for collecting compressed/quantized data in networked systems. We will show how lattice quantization can balance privacy and utility in distributed learning.
