Fixed point theory and semidefinite programming for computable performance analysis of block-sparsity recovery
Gongguo Tang, Arye Nehorai
In this paper, we employ fixed point theory and semidefinite programming to compute the performance bounds on convex block-sparsity recovery algorithms. As a prerequisite for optim…

Verifiable and computable performance analysis of sparsity recovery
Gongguo Tang, Arye Nehorai
In this paper, we develop verifiable and computable performance analysis of sparsity recovery. We define a family of goodness measures for arbitrary sensing matrices as a set of op…
