DeMythif.AI MSCA COFUND

DeMythif.AI est un programme international de formation doctorale et de développement de carrière porté par l’Université Paris-Saclay. Il réunit 19 partenaires académiques et industriels autour d’un objectif commun : renforcer l’excellence scientifique et accompagner le développement professionnel de 25 doctorants en Île-de-France.

Malgré les performances remarquables de l’intelligence artificielle, la fiabilité de ses décisions reste un enjeu scientifique majeur. Comment évaluer le degré de confiance que l’on peut accorder aux résultats produits par les modèles ? Cette question recouvre des enjeux stratégiques, de l’estimation des incertitudes dans les simulations numériques à l’analyse des réactions des systèmes dans des environnements ouverts.

Mieux prendre en compte les incertitudes, qu’elles concernent les données d’entrée ou les résultats des modèles, est essentiel pour renforcer la confiance dans les applications de l’IA. DeMythif.AI explore ainsi plusieurs approches – modèles fondés sur la physique, edge computing, méthodes frugales en données ou encore interactions humain-machine – et leurs applications dans de nombreux domaines : énergie, adaptation au changement climatique, bio-informatique, ingénierie, sciences fondamentales et science des matériaux.

L’intelligence artificielle est aujourd’hui une technologie omniprésente, en constante évolution, dont les champs d’application ne cessent de s’élargir.

Le programme s’articule autour de 3 axes scientifiques interdisciplinaires

 

Quantification des incertitudes

Prendre en compte les incertitudes liées aux données et aux modèles, et quantifier celles associées aux prédictions.

Maîtrise de l’explicabilité

Permettre de comprendre et d’expliquer à l’humain les résultats produits par les modèles entraînés, afin d’en renforcer la confiance.

Encourager la frugalité

Réduire les besoins en données annotées et en énergie nécessaires à l’entraînement des modèles, afin de favoriser le développement d’applications concrètes, au-delà des simples preuves de concept.

Les doctorants bénéficieront de programmes scientifiques d’excellence, d’un encadrement de qualité et de périodes d’immersion en entreprise. Ils profiteront également d’un accompagnement personnalisé dans leur développement professionnel et de formations aux compétences transversales : relations interpersonnelles, communication, numérique, entrepreneuriat, science ouverte, égalité de genre et éthique.

La force de DeMythif.AI réside dans la diversité de ses partenaires, qui permet d’adapter au mieux l’accompagnement proposé aux doctorants, notamment dans la perspective de leur développement professionnel. Cette diversité favorise également la mise en place de collaborations de recherche dynamiques et le développement de synergies fortes entre les communautés académiques et industrielles, ouvrant ainsi de nouvelles perspectives au-delà du projet.

DeMythif.AI bénéficie d’un soutien majeur de l’Institut DataIA Paris-Saclay, de l’Union européenne et des Actions Marie Skłodowska-Curie (MSCA). Au-delà du financement européen qu’elles apportent, les MSCA constituent également un véritable label d’excellence.
