Refitting solutions promoted by $ℓ_{12}$ sparse analysis regularization with block penalties

Charles-Alban Deledalle, Nicolas Papadakis, Joseph Salmon +1

In inverse problems, the use of an $ℓ_{12}$ analysis regularizer induces a bias in the estimated solution. We propose a general refitting framework for removing this artifact wh…

Risk estimation for matrix recovery with spectral regularization

Charles-Alban Deledalle, Samuel Vaiter, Gabriel Peyré +2

In this paper, we develop an approach to recursively estimate the quadratic risk for matrix recovery problems regularized with spectral functions. Toward this end, in the spirit of…
