Feature Selection for Vertex Discriminant Analysis
Alfonso Landeros, Tong Tong Wu, Kenneth Lange
We revisit vertex discriminant analysis (VDA) from the perspective of proximal distance algorithms. By specifying sparsity sets as constraints that directly control the number of a…
MM Algorithms for Variance Components Models
Hua Zhou, Liuyi Hu, Jin Zhou +1
Variance components estimation and mixed model analysis are central themes in statistics with applications in numerous scientific disciplines. Despite the best efforts of generatio…
A Path Algorithm for Constrained Estimation
Hua Zhou, Kenneth Lange
Many least squares problems involve affine equality and inequality constraints. Although there are variety of methods for solving such problems, most statisticians find constrained…
Graphics Processing Units and High-Dimensional Optimization
Hua Zhou, Kenneth Lange, Marc A. Suchard
This paper discusses the potential of graphics processing units (GPUs) in high-dimensional optimization problems. A single GPU card with hundreds of arithmetic cores can be inserte…
