2/5 Stephen Becker Seminar

Stephen Becker will be presenting a TCP Seminar on February 5th. The seminar will give a brief introduction to compressed sensing, which is a theory developed in 2004 that shows how, in an appropriate setting, to be able to take many fewer measurements of a signal than the classical limit. It does this by exploiting compressibility in a particular way. An extension of compressed sensing is matrix completion, which fills in missing entries in a matrix by exploiting another type of compressibility. Applications of both theories were initially mostly for signal processing, but the applications are increasingly turning toward data processing and general machine learning.
