Optimisation topologique magnéto-mécanique d’un rotor de machine électrique synchro-réluctante

L’optimisation topologique est une classe de méthodes de conception automatique d’objets techniques qui ne nécessite pas d’information préalable sur leur géométrie et permet de s’affranchir des biais de conception. Cette méthodologie est appliquée à…

Beyond the Norms: Detecting Prediction Errors in Regression Models

This paper tackles the challenge of detecting unreliable behavior in regression algorithms, which may arise from intrinsic variability (e.g., aleatoric uncertainty) or modeling errors (e.g., model uncertainty). First, we formally introduce the…
