Robust Polyhedral Regularization
Samuel Vaiter, Gabriel Peyré, Jalal Fadili
In this paper, we establish robustness to noise perturbations of polyhedral regularization of linear inverse problems. We provide a sufficient condition that ensures that the polyh…
Stein COnsistent Risk Estimator (SCORE) for hard thresholding
Charles-Alban Deledalle, Gabriel Peyré, Jalal Fadili
In this work, we construct a risk estimator for hard thresholding which can be used as a basis to solve the difficult task of automatically selecting the threshold. As hard thresho…
The degrees of freedom of the Group Lasso for a General Design
Samuel Vaiter, Charles Deledalle, Gabriel Peyré +2
In this paper, we are concerned with regression problems where covariates can be grouped in nonoverlapping blocks, and where only a few of them are assumed to be active. In such a…
