Analyzing Weighted ℓ1​ Minimization for Sparse Recovery with Nonuniform Sparse Models\footnote{The results of this paper were presented in part at the International Symposium on Information Theory, ISIT 2009}

M. Amin Khajehnejad, Weiyu Xu, A. Salman Avestimehr +1

In this paper we introduce a nonuniform sparsity model and analyze the performance of an optimized weighted ℓ1​ minimization over that sparsity model. In particular, we focus…

Improved Sparse Recovery Thresholds with Two-Step Reweighted ℓ1​ Minimization

M. Amin Khajehnejad, Weiyu Xu, Salman Avestimehr +1

It is well known that ℓ1​ minimization can be used to recover sufficiently sparse unknown signals from compressed linear measurements. In fact, exact thresholds on the sparsit…
