A Majorization-Minimization Gauss-Newton Method for 1-Bit Matrix Completion

Xiaoqian Liu, Xu Han, Eric C. Chi +1

In 1-bit matrix completion, the aim is to estimate an underlying low-rank matrix from a partial set of binary observations. We propose a novel method for 1-bit matrix completion ca…

Robust Low-rank Tensor Decomposition with the Criterion

Qiang Heng, Eric C. Chi, Yufeng Liu

The growing prevalence of tensor data, or multiway arrays, in science and engineering applications motivates the need for tensor decompositions that are robust against outliers. In…

Proximal MCMC for Bayesian Inference of Constrained and Regularized Estimation

Xinkai Zhou, Qiang Heng, Eric C. Chi +1

This paper advocates proximal Markov Chain Monte Carlo (ProxMCMC) as a flexible and general Bayesian inference framework for constrained or regularized estimation. Originally intro…

A Sharper Computational Tool for Regression

Xiaoqian Liu, Eric C. Chi, Kenneth Lange

Building on previous research of Chi and Chi (2022), the current paper revisits estimation in robust structured regression under the criterion. We adopt the ma…

Bayesian Trend Filtering via Proximal Markov Chain Monte Carlo

Qiang Heng, Hua Zhou, Eric C. Chi

Proximal Markov Chain Monte Carlo is a novel construct that lies at the intersection of Bayesian computation and convex optimization, which helped popularize the use of nondifferen…

A Convex-Nonconvex Strategy for Grouped Variable Selection

Xiaoqian Liu, Aaron J. Molstad, Eric C. Chi

This paper deals with the grouped variable selection problem. A widely used strategy is to augment the negative log-likelihood function with a sparsity-promoting penalty. Existing…
