Recovery of Sparse Matrices via Matrix Sketching
Thakshila Wimalajeewa, Yonina C. Eldar, Pramod K. Varshney
In this paper, we consider the problem of recovering an unknown sparse matrix X from the matrix sketch Y = AX B^T. The dimension of Y is less than that of X, and A and B are known…
OMP Based Joint Sparsity Pattern Recovery Under Communication Constraints
Thankshila Wimalajeewa, Pramod K. Varshney
We address the problem of joint sparsity pattern recovery based on low dimensional multiple measurement vectors (MMVs) in resource constrained distributed networks. We assume that…
Subspace Recovery from Structured Union of Subspaces
Thakshila Wimalajeewa, Yonina C. Eldar, Pramod K. Varshney
Lower dimensional signal representation schemes frequently assume that the signal of interest lies in a single vector space. In the context of the recently developed theory of comp…
