A Lifted $\ell_1 $ Framework for Sparse Recovery

no code implementations10 Mar 2022 Yaghoub Rahimi, Sung Ha Kang, Yifei Lou

Motivated by re-weighted $\ell_1$ approaches for sparse recovery, we propose a lifted $\ell_1$ (LL1) regularization which is a generalized form of several popular regularizations in the literature.

A Scale Invariant Approach for Sparse Signal Recovery

no code implementations20 Dec 2018 Yaghoub Rahimi, Chao Wang, Hongbo Dong, Yifei Lou

In this paper, we study the ratio of the $L_1 $ and $L_2 $ norms, denoted as $L_1/L_2$, to promote sparsity.
