Reference-free logged energy-oracle recovery for neural approximations of symmetric coercive variational problems: conforming Riesz reconstruction and archive-level selection
Karim Bounja, Lahcen Laayouni, Boujemaa Achchab +1
Neural PDE training yields a finite checkpoint archive, yet its logged energy errors are inaccessible without the exact solution, while loss-based selection does not necessarily re…
Intrinsic perturbation scale for certified oracle objectives with epigraphic information
Karim Bounja, Boujemaâ Achchab, Abdeljalil Sakat
We introduce a natural displacement control for minimizer sets of oracle objectives equipped with certified epigraphic information. Formally, we replace the usual local uniform val…
Variable selection for clustering with Gaussian mixture models: state of the art
Abdelghafour Talibi, Boujemâa Achchab, Rafik Lasri
The mixture models have become widely used in clustering, given its probabilistic framework in which its based, however, for modern databases that are characterized by their large…
