Geometry-preserving Lie Group Integrators For Differential Equations On The Manifold Of Symmetric Positive Definite Matrices

no code implementations17 Oct 2022 Lucas Drumetz, Alexandre Reiffers-Masson, Naoufal El Bekri, Franck Vermet

The application of Euclidean methods to integrate differential equations lying on such objects does not respect the geometry of the manifold, which can cause many numerical issues.

Some Remarks on Replicated Simulated Annealing

no code implementations30 Sep 2020 Vincent Gripon, Matthias Löwe, Franck Vermet

Recently authors have introduced the idea of training discrete weights neural networks using a mix between classical simulated annealing and a replica ansatz known from the statistical physics literature.

Interpretabilité des modèles : état des lieux des méthodes et application à l'assurance

no code implementations25 Jul 2020 Dimitri Delcaillau, Antoine Ly, Franck Vermet, Alizé Papp
