Continuous Methods : Adaptively intrusive reduced order model closure

Autor: Menier, Emmanuel, Bucci, Michele Alessandro, Yagoubi, Mouadh, Mathelin, Lionel, Dairay, Thibault, Meunier, Raphael, Schoenauer, Marc

Reduced order modeling methods are often used as a mean to reduce simulation costs in industrial applications. Despite their computational advantages, reduced order models (ROMs) often fail to accurately reproduce complex dynamics encountered in real

Continuous Methods : Hamiltonian Domain Translation

Autor: Menier, Emmanuel, Bucci, Michele Alessandro, Yagoubi, Mouadh, Mathelin, Lionel, Schoenauer, Marc

This paper proposes a novel approach to domain translation. Leveraging established parallels between generative models and dynamical systems, we propose a reformulation of the Cycle-GAN architecture. By embedding our model with a Hamiltonian structur

On the linear convergence rates of exchange and continuous methods for total variation minimization

Autor: Flinth, Axel, de Gournay, Frédéric, Weiss, Pierre

We analyze an exchange algorithm for the numerical solution total-variation regularized inverse problems over the space M($\Omega$) of Radon measures on a subset $\Omega$ of R d. Our main result states that under some regularity conditions, the metho
