The degrees of freedom of the Lasso for general design matrix
Charles Dossal, Maher Kachour, Jalal M. Fadili +2
In this paper, we investigate the degrees of freedom ($\dof$) of penalized minimization (also known as the Lasso) for linear regression models. We give a closed-form expre…
Robust Sparse Analysis Regularization
Samuel Vaiter, Gabriel Peyré, Charles Dossal +1
This paper investigates the theoretical guarantees of L1-analysis regularization when solving linear inverse problems. Most of previous works in the literature have mainly focused…
Sharp Support Recovery from Noisy Random Measurements by L1 minimization
Charles Dossal, Marie-Line Chabanol, Gabriel Peyré +1
In this paper, we investigate the theoretical guarantees of penalized $\lun$ minimization (also called Basis Pursuit Denoising or Lasso) in terms of sparsity pattern recovery (supp…
