Riemannian Conjugate Gradient Descent Method for Third-Order Tensor Completion
Guang-Jing Song, Xue-Zhong Wang, Michael K. Ng
The goal of tensor completion is to fill in missing entries of a partially known tensor under a low-rank constraint. In this paper, we mainly study low rank third-order tensor comp…

Nonnegative Low Rank Matrix Approximation for Nonnegative Matrices
Guang-Jing Song, Michael Kwok-Po Ng
This paper describes a new algorithm for computing Nonnegative Low Rank Matrix (NLRM) approximation for nonnegative matrices. Our approach is completely different from classical no…

Bilinear Constraint based ADMM for Mixed Poisson-Gaussian Noise Removal
Jie Zhang, Yuping Duan, Yue Lu +2
In this paper, we propose new operator-splitting algorithms for the total variation regularized infimal convolution (TV-IC) model [4] in order to remove mixed Poisson-Gaussian(MPG)…
