Accelerated Schemes for the $L_{1} / L_{2}$ Minimization

Chao Wang, Ming Yan, Yaghoub Rahimi +1

In this paper, we consider the $L_{1} / L_{2}$ minimization for sparse recovery and study its relationship with the $L_{1}$ - $α L_{2}$ 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 $L_{1}$ and $L_{2}$ norms, denoted as $L_{1} / L_{2}$ , to promote sparsity. Due to the non-convexity and non-linearity, there has been little atten…
