Orthogonal Rank-One Matrix Pursuit for Low Rank Matrix Completion
Zheng Wang, Ming-Jun Lai, Zhaosong Lu +3
In this paper, we propose an efficient and scalable low rank matrix completion algorithm. The key idea is to extend orthogonal matching pursuit method from the vector case to the m…
A General Iterative Shrinkage and Thresholding Algorithm for Non-convex Regularized Optimization Problems
Pinghua Gong, Changshui Zhang, Zhaosong Lu +2
Non-convex sparsity-inducing penalties have recently received considerable attentions in sparse learning. Recent theoretical investigations have demonstrated their superiority over…
Fused Multiple Graphical Lasso
Sen Yang, Zhaosong Lu, Xiaotong Shen +2
In this paper, we consider the problem of estimating multiple graphical models simultaneously using the fused lasso penalty, which encourages adjacent graphs to share similar struc…
Sparse Approximation via Penalty Decomposition Methods
Zhaosong Lu, Yong Zhang
In this paper we consider sparse approximation problems, that is, general minimization problems with the -"norm" of a vector being a part of constraints or objective fun…
