A sparsity preserving stochastic gradient methods for sparse regression

Lin, Qihang; Chen, Xi; Peña, Javier - In: Computational Optimization and Applications 58 (2014) 2, pp. 455-482

We propose a new stochastic first-order algorithm for solving sparse regression problems. In each iteration, our …

A Bayesian Analysis Strategy for Cross-Study Translation of Gene Expression Biomarkers

Lucas, Joseph; Carvalho, Carlos; West, Mike - In: Statistical Applications in Genetics and Molecular Biology 8 (2009) 1, pp. 11-11

We describe a strategy for the analysis of experimentally derived gene expression signatures and their translation to human observational data. Sparse multivariate regression models are used to identify expression signature gene sets representing downstream biological pathway events following...
