Distance Majorization and Its Applications
Eric C. Chi, Hua Zhou, Kenneth Lange
The problem of minimizing a continuously differentiable convex function over an intersection of closed convex sets is ubiquitous in applied mathematics. It is particularly interest…
Regularized Matrix Regression
Hua Zhou, Lexin Li
Modern technologies are producing a wealth of data with complex structures. For instance, in two-dimensional digital imaging, flow cytometry, and electroencephalography, matrix typ…
Tensor Regression with Applications in Neuroimaging Data Analysis
Hua Zhou, Lexin Li, Hongtu Zhu
Classical regression methods treat covariates as a vector and estimate a corresponding vector of regression coefficients. Modern applications in medical imaging generate covariates…
Path Following in the Exact Penalty Method of Convex Programming
Hua Zhou, Kenneth Lange
Classical penalty methods solve a sequence of unconstrained problems that put greater and greater stress on meeting the constraints. In the limit as the penalty constant tends to $…
A Generic Path Algorithm for Regularized Statistical Estimation
Hua Zhou, Yichao Wu
Regularization is widely used in statistics and machine learning to prevent overfitting and gear solution towards prior information. In general, a regularized estimation problem mi…
Path Following and Empirical Bayes Model Selection for Sparse Regression
Hua Zhou, Artin Armagan, David B. Dunson
In recent years, a rich variety of regularization procedures have been proposed for high dimensional regression problems. However, tuning parameter choice and computational efficie…
