(2024)\n. The method enables the\nselection and aggregation of large-scale rare binary features\nwith a known hierarchical structure using a convex,\nlinearly-constrained regularized regression framework. The\npackage facilitates the application of this method to both\nlinear regression and binary classification problems by solving\nthe optimization problem via the smoothing proximal gradient\ndescent algorithm (Chen et al. (2012)\n).", "License": "GPL-3", "Encoding": "UTF-8", "LazyData": "true", "RoxygenNote": "7.2.1", "NeedsCompilation": "yes", "Packaged": { "Date": "2026-06-01 11:32:47 UTC", "User": "root" },
