Right Bregman proximal gradient with application to Poisson inverse problems *
Thibaut Modrzyk, Elie Bretin, Voichita Maxim
We introduce a novel Bregman proximal algorithm for convex composite optimization by applying the standard Bregman proximal gradient (BPG) method to a mirror-coordinate reparameter…
Learning the Willmore flow with a lightweight neural operator
Elie Bretin, Roland Denis, Tokuhiro Eto +1
We extend to the Willmore flow the phase-field neural operator approach proposed by Bretin, Denis, Masnou, and Terii (2022) for mean curvature motion in two and three dimensions. T…
A convergent Plug-and-Play Majorization-Minimization algorithm for Poisson inverse problems
Thibaut Modrzyk, Ane Etxebeste, Élie Bretin +1
In this paper, we present a novel variational plug-and-play algorithm for Poisson inverse problems. Our approach minimizes an explicit functional which is the sum of a Kullback-Lei…
