Matrix Completion and Partial Realization via Compressed Sensing

Compressed sensing refers to the problem of reconstructing large but sparse objects from a limited number of measurements.  Within this broad topic, matrix  completion refers to the problem of reconstructing a large but low rank matrix from measurements of just a few of its components.  This is a relatively new area of research.  Partial realization, in contrast, is a 50 year-old problem of completing a partially observed unit pulse response of a control system with a dynamical model of minimal order.  In this talk, I will describe some work due to others (matrix completion) and some of my own on-going research (partial realization) and establish connections between the two topics.
