A sharp oracle inequality for Graph-Slope
Pierre C Bellec, Joseph Salmon, Samuel Vaiter
Following recent success on the analysis of the Slope estimator, we provide a sharp oracle inequality in term of prediction error for Graph-Slope, a generalization of Slope to sign…
Maximal Solutions of Sparse Analysis Regularization
Abdessamad Barbara, Abderrahim Jourani, Samuel Vaiter
This paper deals with the non-uniqueness of the solutions of an analysis-Lasso regularization. Most of previous works in this area is concerned with the case where the solution set…
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…
