Magnetic characterization under PWM and PWM-like excitations

Pulse-Width-Modulation (PWM)-like voltages are typical operating conditions for magnetic cores, but introduce additional complexity in the characterization and loss prediction due to the presence of high-order harmonics, minor hysteresis loops, and…

Solving jigsaw puzzles with vision transformers

Puzzle-solving is a problem having applications for instance in archaeology and cultural heritage. Proposed solutions often suffer from a performance loss when the pieces are eroded, a characteristic that is pervasive across various use—cases such…

Signal and Image processing

Maximum de vraisemblance et apprentissage informé pour l'imagerie dynamique en radioastronomie

This thesis addresses the inverse problem of image reconstruction in radio interferometry. Inverse problems aim to estimate the source parameters likely to have generated observed measurements, based on prior knowledge of a forward model. In radio…

Stochastic Embeddings: A Probabilistic and Geometric Analysis of Out-of-Distribution Behavior

Deep neural networks perform well in many applications but often fail when exposed to outof-distribution (OoD) inputs. We identify a geometric phenomenon in the embedding space: indistribution (ID) data show higher variance than OoD data under…

Optimization and Control

Apprentissage machine et contrôle stochastique pour un pilotage automatique optimisé des systèmes industriels

Optimizing aeration control in wastewater treatment plants is crucial to meet both economic and environmental objectives. The development of advanced control strategies, however, is hindered by the difficulty of calibrating reliable predictive…

Domain-informed and neural-optimized belief assignments: A framework applied to cultural heritage

Identifying pigments in Cultural Heritage artifacts is key to uncovering their origin and guiding conservation strategies. Although recent advances in non-invasive imaging have enabled the collection of rich multimodal data, existing methods often…
