Robust Lasso-Zero for sparse corruption and model selection with missing covariates
Pascaline Descloux, Claire Boyer, Julie Josse +2
We propose Robust Lasso-Zero, an extension of the Lasso-Zero methodology, initially introduced for sparse linear models, to the sparse corruptions problem. We give theoretical guar…
Nonparametric estimation of galaxy cluster's emissivity and point source detection in astrophysics with two lasso penalties
Jairo Diaz-Rodriguez, Dominique Eckert, Hatef Monajemi +2
Astrophysicists are interested in recovering the 3D gas emissivity of a galaxy cluster from a 2D image taken by a telescope. A blurring phenomenon and presence of point sources mak…
denoiseR: A Package for Low Rank Matrix Estimation
Julie Josse, Sylvain Sardy, Stefan Wager
We introduce denoiseR, an R package that provides a unified implementation of several state-of-the-art proposals for regularized low rank matrix estimation, along with automatic se…
