Stable Image Reconstruction via Two-Parameter Power-Scale Variation Minimization

Ziwei Li, Wengu Chen, Huanmin Ge +2

In this article, we introduce a power-scale variation (PSV $_{a, p}$ ) with two tunable parameters: the sparsity-inducing exponent $p \in (0, 1]$ and the scaling factor $a \in (0, \infty)$ .…

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…

On the Performance of Amplitude-Based Models for Low-Rank Matrix Recovery

Huanmin Ge, Zhiqiang Xu

In this paper, we focus on low-rank phase retrieval, which aims to reconstruct a matrix $X_{0} \in R^{n \times m}$ with $rank (X_{0}) \leq r$ from noi…
