Data-driven Evolutions of Critical Points
Stefano Almi, Massimo Fornasier, Richard Huber
In this paper we are concerned with the learnability of energies from data obtained by observing time evolutions of their critical points starting at random initial equilibria. As…

Coupled regularization with multiple data discrepancies
Martin Holler, Richard Huber, Florian Knoll
We consider a class of regularization methods for inverse problems where a coupled regularization is employed for the simultaneous reconstruction of data from multiple sources. App…
