Title: Enhanced Compressive Sensing and More

Abstract: We consider the equivalence between finding the sparsest vector in a set and continuous optimization on the same set.  This approach enables remarkably simple proofs to unify and extend some compressive sensing recoverability and stability results, and reveals potential benefits of doing enhanced compressive sensing (ECS) where prior information could allow recovery of much less sparse signals.

We will also introduce some recent algorithmic work done by our CAAM group at Rice University.
