Gap Safe Screening Rules for Sparsity Enforcing PenaltiesMS54

In high dimensional regression settings, sparsity enforcing penalties have proved useful to regularize the data-fitting term. A recently introduced technique called screening rules propose to ignore some variables in the optimization leveraging the expected sparsity of the solutions and consequently leading to faster solvers. In this work, we propose a unifying framework for generalized linear models regularized with standard sparsity enforcing penalties such as l1 or l1/l2 norms.
