Package: sglssnal Title: Sparse-Group Lasso via Semismooth Newton Augmented Lagrangian Version: 0.1.0 Authors@R: c( person("Robin", "Liu", , "robin28liu@gmail.com", role = c("aut", "cre")), person("Yangjing", "Zhang", role = "ctb", comment = "Author of the original MATLAB SSNAL implementation this package ports")) Description: Implements the sparse-group lasso method of Zhang et al. (2020) . Unlike many widely available methods based on first-order descent, this method uses second-order information to solve the dual optimization problem via a semismooth Newton method.
