The DFR approach is a feature\nreduction approach that applies strong screening to reduce the\nfeature space before optimisation, leading to speed-up\nimprovements for fitting SGL (Simon et al. (2013)\n) and aSGL (Mendez-Civieta et\nal. (2020) and Poignard (2020)\n) models. DFR is implemented\nusing the Adaptive Three Operator Splitting (ATOS) (Pedregosa\nand Gidel (2018) ) algorithm,\nwith linear and logistic SGL models supported, both of which\ncan be fit using k-fold cross-validation. Dense and sparse\ninput matrices are supported.", "Roxygen": "list(markdown = TRUE)", "RoxygenNote": "7.3.1", "License": "GPL (>= 3)", "Encoding": "UTF-8", "URL": "https://github.com/ff1201/dfr",
