An augmented Lagrangian method with exact multipliers for non-separable composite $ℓ_{0}$ - $ℓ_{2}$ regularization

Huan Ren, Guiyun Xiao

This paper studies a non-separable composite $ℓ_{0}$ - $ℓ_{2}$ regularization model that simultaneously enforces sparsity and smoothness for inverse problems. The $ℓ_{0}$ norm ind…

Single-pass randomized QLP decomposition for low-rank approximation

Huan Ren, Zheng-Jian Bai

The QLP decomposition is one of the effective algorithms to approximate singular value decomposition (SVD) in numerical linear algebra. In this paper, we propose some single-pass r…
