Richness of Sparsity: Random matrices, Remote Sensing and
Harmonic Analysis
October 28, 2009 3pm, 201 SEC
Abstract
Many seemingly complex phenomena in areas such as physics, engineering or
medicine, have a sparse representation in the sense that they can be
described by a linear combination of a few elementary building blocks. This
concept, known as sparsity, has gained tremendous attention in recent
years, fueled by the advent of Compressed Sensing. I will demonstrate how
insights from sparsity and compressed sensing lead to dramatic improvements
in remote sensing, making it possible to solve problems in radar imaging
that were hitherto believed to be intractable. Underlying this breakthrough
is a rigorous mathematical analysis that uses tools from random matrix
theory and applied harmonic analysis.
I will conclude my talk with a bold perspective of the future of sparsity
and compressed sensing.
