Efficient Projection Algorithms onto the Weighted l1 Ball

no code implementations7 Sep 2020 Guillaume Perez, Sebastian Ament, Carla Gomes, Michel Barlaud

In this paper we propose three new efficient algorithms for projecting any vector of finite length onto the weighted $\ell_1$ ball.

Clustering with feature selection using alternating minimization, Application to computational biology

no code implementations8 Nov 2017 Cyprien Gilet, Marie Deprez, Jean-Baptiste Caillau, Michel Barlaud

The projection-gradient step is a method of splitting type, with exact projection on the $\ell^1$ ball to promote sparsity.

Non-convex regularization in remote sensing

1 code implementation23 Jun 2016 Devis Tuia, Remi Flamary, Michel Barlaud

In this paper, we study the effect of different regularizers and their implications in high dimensional image classification and sparse linear unmixing.
