"Theory of Codes in Network and Inference Problems"

Arya Mazumdar, Assistant Professor, ECE, University of Minnesota - Twin Cities

November 4th (Wednesday), 11:00am
Harold Frank Hall (HFH), Room 4164


Due to applications in large-scale distributed storage systems, local encoding and repair properties of codes have recently earned a lot of attention. In the first part of the talk, we show that generalized locality properties of codes lead to the notion of a graph capacity that is fundamental in the study of network flow problems. Furthermore, this capacity is closely related to the steady-states of graph dynamical systems, and thus steer us towards applications in neural auto-associative memories and consensus-based community detection algorithms.

In the second part of the talk we will address another general application of codes motivated by the pseudo-random behavior of code-words distribution. We will show how this basic principle is used to provide deterministic construction of structured matrices for applications such as sparse recovery and low-rank approximation.
