Safe feature screening for generalized lasso
WebScreening rules leverage the known sparsity of the solution by ignoring some variables in the optimization, hence speeding up solvers. When the procedure is proven not to discard features wrongly the rules are said to be safe. In this paper we derive new safe rules for generalized linear models regularized with ‘ 1 and ‘ 1{‘ 2 norms. The ... WebJan 1, 2024 · 1. We propose a novel optimization framework for lasso screening that combines SSR with simple safe rules, resulting in a family of hybrid safe–strong rules (HSSR) that are more efficient and scalable to large-scale data sets. 2. We develop two instances of HSSR, namely SSR-Dome and SSR-BEDPP, for feature screening in solving …
