Blind inverse problems with isolated spikes
Valentin Debarnot, Pierre Weiss
Assume that an unknown integral operator living in some known subspace is observed indirectly, by evaluating its action on a few Dirac masses at unknown locations. Is this informat…

A scalable estimator of sets of integral operators
Valentin Debarnot, Paul Escande, Pierre Weiss
We propose a scalable method to find a subspace of low-rank tensors that simultaneously approximates a set of integral operators. The method can be seen as…
