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.
