Fast algorithms for robust principal component analysis with an upper bound on the rank

Ningyu Sha, Lei Shi, Ming Yan

The robust principal component analysis (RPCA) decomposes a data matrix into a low-rank part and a sparse part. There are mainly two types of algorithms for RPCA. The first type of…

A Novel Regularization Based on the Error Function for Sparse Recovery

Weihong Guo, Yifei Lou, Jing Qin +1

Regularization plays an important role in solving ill-posed problems by adding extra information about the desired solution, such as sparsity. Many regularization terms usually inv…

Variational Asymptotic Preserving Scheme for the Vlasov-Poisson-Fokker-Planck System

Jose A. Carrillo, Li Wang, Wuzhe Xu +1

We design a variational asymptotic preserving scheme for the Vlasov-Poisson-Fokker-Planck system with the high field scaling, which describes the Brownian motion of a large system…

A Multi-Agent Primal-Dual Strategy for Composite Optimization over Distributed Features

Sulaiman A. Alghunaim, Ming Yan, Ali H. Sayed

This work studies multi-agent sharing optimization problems with the objective function being the sum of smooth local functions plus a convex (possibly non-smooth) function couplin…
