Marie Michenková - A Brief Introduction to Compressed Sensing and Low-Rank Matrix Completion Problems

Kdy: 22/10/2013 12:20
Kde: Seminární místnost KNM

Both compressed sensing and low-rank matrix recovery are recent 
and quickly developing sampling theories. In compressed sensing,
the aim is to recover a sparse solution to an underdetermined
system of equations. In low-rank matrix completion, we recover
a low-rank data matrix from sampling of its entries. In the talk I will
give a brief introduction to both theories and will explain the relation
between them. If the time allows, I will also present some standard
approaches to handle these problems.
