Breaking through the Thresholds: an Analysis for Iterative Reweighted Minimization via the Grassmann Angle Framework
Weiyu Xu, M. Amin Khajehnejad, Salman Avestimehr +1
It is now well understood that minimization algorithm is able to recover sparse signals from incomplete measurements [2], [1], [3] and sharp recoverable sparsity threshold…
Sparse Recovery of Positive Signals with Minimal Expansion
M. Amin Khajehnejad, Alexandros G. Dimakis, Weiyu Xu +1
We investigate the sparse recovery problem of reconstructing a high-dimensional non-negative sparse vector from lower dimensional linear measurements. While much work has focused o…
Weighted Minimization for Sparse Recovery with Prior Information
M. Amin Khajehnejad, Weiyu Xu, Salman Avestimehr +1
In this paper we study the compressed sensing problem of recovering a sparse signal from a system of underdetermined linear equations when we have prior information about the proba…
