A Novel Two-Parameter Penalty: Relaxation Degree Analysis and Sparse Signal Recovery

Ziwei Li, Wengu Chen, Huanmin Ge +1

In this article, we introduce a nonconvex two-parameter penalty function $P_{a,p}$, parameterized by $a\in (0,\infty )$ and $p\in (0,1]$, and the relaxation degree RD${}_P$ for a separa…
