Support matrix machine: exploring sample sparsity, low rank, and adaptive sieving in high-performance computing

Can Wu, Dong-Hui Li, Defeng Sun

Support matrix machine (SMM) is a successful supervised classification model for matrix-type samples. Unlike support vector machines, it employs low-rank regularization on the regr…

Lipschitz stability of least-squares problems regularized by functions with -cone reducible conjugates

Ying Cui, Tim Hoheisel, Tran T. A. Nghia +1

In this paper, we study Lipschitz continuity of the solution mappings of regularized least-squares problems for which the convex regularizers have (Fenchel) conjugates that are $\m…

Characterizations of the Aubin Property of the Solution Mapping for Nonlinear Semidefinite Programming

Liang Chen, Ruoning Chen, Defeng Sun +1

In this paper, we study the Aubin property of the Karush-Kuhn-Tucker solution mapping for the nonlinear semidefinite programming (NLSDP) problem at a locally optimal solution. In t…

Aubin Property and Strong Regularity Are Equivalent for Nonlinear Second-Order Cone Programming

Liang Chen, Ruoning Chen, Defeng Sun +1

This paper solves a fundamental open problem in variational analysis on the equivalence between the Aubin property and the strong regularity for nonlinear second-order cone program…
