Split Bregman Method for Sparse Inverse Covariance Estimation with Matrix Iteration Acceleration
Gui-Bo Ye, Jian-Feng Cai, Xiaohui Xie
We consider the problem of estimating the inverse covariance matrix by maximizing the likelihood function with a penalty added to encourage the sparsity of the resulting matrix. We…

Learning sparse gradients for variable selection and dimension reduction
Gui-Bo Ye, Xiaohui Xie
Variable selection and dimension reduction are two commonly adopted approaches for high-dimensional data analysis, but have traditionally been treated separately. Here we propose a…

Split Bregman method for large scale fused Lasso
Gui-Bo Ye, Xiaohui Xie
rdering of regression or classification coefficients occurs in many real-world applications. Fused Lasso exploits this ordering by explicitly regularizing the differences between n…
