An iterative algorithm for sparse and constrained recovery with applications to divergence-free current reconstructions in magneto-encephalography
Ignace Loris, Caroline Verhoeven
We propose an iterative algorithm for the minimization of a -norm penalized least squares functional, under additional linear constraints. The algorithm is fully explicit:…

On a generalization of the iterative soft-thresholding algorithm for the case of non-separable penalty
Ignace Loris, Caroline Verhoeven
An explicit algorithm for the minimization of an penalized least squares functional, with non-separable term, is proposed. Each step in the iterative algorithm re…

Practical error estimates for sparse recovery in linear inverse problems
Ignace Loris, Caroline Verhoeven
The effectiveness of using model sparsity as a priori information when solving linear inverse problems is studied. We investigate the reconstruction quality of such a method in the…
