Block based refitting in sparse regularisation
Charles-Alban Deledalle, Nicolas Papadakis, Joseph Salmon +1
In many linear regression problems, including ill-posed inverse problems in image restoration, the data exhibit some sparse structures that can be used to regularize the inversion.…
The Degrees of Freedom of Partly Smooth Regularizers
Samuel Vaiter, Charles-Alban Deledalle, Jalal M. Fadili +2
In this paper, we are concerned with regularized regression problems where the prior regularizer is a proper lower semicontinuous and convex function which is also partly smooth re…
The Degrees of Freedom of the Group Lasso
Samuel Vaiter, Charles Deledalle, Gabriel Peyré +2
This paper studies the sensitivity to the observations of the block/group Lasso solution to an overdetermined linear regression model. Such a regularization is known to promote spa…
