Safe Peeling for L0-Regularized Least-Squares with supplementary material
Théo Guyard, Gilles Monnoyer, Clément Elvira +1
We introduce a new methodology dubbed ``safe peeling'' to accelerate the resolution of L0-regularized least-squares problems via a Branch-and-Bound (BnB) algorithm. Our procedure e…
Beyond GAP screening for Lasso by exploiting new dual cutting half-spaces with supplementary material
Thu-Le Tran, Clément Elvira, Hong-Phuong Dang +1
In this paper, we propose a novel safe screening test for Lasso. Our procedure is based on a safe region with a dome geometry and exploits a canonical representation of the set of…
Safe rules for the identification of zeros in the solutions of the SLOPE problem
Clément Elvira, Cédric Herzet
In this paper we propose a methodology to accelerate the resolution of the so-called "Sorted L-One Penalized Estimation" (SLOPE) problem. Our method leverages the concept of "safe…
Safe squeezing for antisparse coding
Clément Elvira, Cédric Herzet
Spreading the information over all coefficients of a representation is a desirable property in many applications such as digital communication or machine learning. This so-called a…
