A Lifted Framework for Sparse Recovery
Yaghoub Rahimi, Sung Ha Kang, Yifei Lou
Motivated by re-weighted approaches for sparse recovery, we propose a lifted (LL1) regularization which is a generalized form of several popular regularizations i…

Accelerated Schemes for the Minimization
Chao Wang, Ming Yan, Yaghoub Rahimi +1
In this paper, we consider the minimization for sparse recovery and study its relationship with the - model. Based on this relationship, we propose three nu…

A Scale Invariant Approach for Sparse Signal Recovery
Yaghoub Rahimi, Chao Wang, Hongbo Dong +1
In this paper, we study the ratio of the and norms, denoted as , to promote sparsity. Due to the non-convexity and non-linearity, there has been little atten…
