Effective regions and kernels in continuous sparse regularisation, with application to sketched mixtures
Yohann De Castro, Rémi Gribonval, Nicolas Jouvin
This paper advances the general theory of continuous sparse regularisation on measures with the Beurling-LASSO (BLASSO). This TV-regularised convex program on the space of measures…

Blind calibration for compressed sensing by convex optimization
Rémi Gribonval, Gilles Chardon, Laurent Daudet
We consider the problem of calibrating a compressed sensing measurement system under the assumption that the decalibration consists in unknown gains on each measure. We focus on {\…
