Nathan Godey a reçu, lors de la conférence CORIA-TALN 2025, le prix de thèse ATALA 2025.
Nathan était un doctorant PRAIRIE, encadré par Benoît Sagot et Eric de la Clergerie et membre de l’équipe Almanach du centre Inria de Paris, un grand bravo à lui pour ses travaux !

La thèse de Nathan Godey s’attache à dépasser les limitations structurelles de l’apprentissage de représentations dans les architectures neuronales. À partir d’une analyse fine, mobilisant des méthodes d’interprétabilité, il propose une contribution conceptuelle forte : une méthode d’entraînement de modèles de langue qui s’affranchit du calcul de la distribution des symboles de sortie, en mobilisant des techniques d’apprentissage contrastif. Cette approche originale, dite headless, vise à reconstruire des séquences de plongements lexicaux en entrée, sans recourir à une tête de décodage pendant l’apprentissage. Un travail expérimental exigeant, systématique et d’un haut niveau de compétence technique a permis de démontrer l’efficacité de ce nouveau paradigme, tant en termes d’usage mémoire que de vitesse de convergence. La diversité des thématiques abordées (segmentation en unités sous-lexicales, analyse des représentations, lois d’échelle, optimisation de l’apprentissage), ainsi qu’une aptitude bienvenue à la formalisation, se sont concrétisées à chaque fois par des publications originales dans des supports de très grande qualité.

La vision artificielle rattrapée par la physique

Les deux professeurs d’informatique soulignent, dans leur Carte blanche au « Monde », que le développement de ce pilier de l’intelligence artificielle, dont les applications nécessitent une extrême précision, oblige à mobiliser des alternatives à l’IA générative moins coûteuses et sujettes aux hallucinations.

The second call for project for the Sophie Germain programme of the French Embassy in the United Kingdom

On the 29th of February 2024, the Franco-British Joint Committee for Science and Technology was held in London. The French and British governments agreed to provide funding for joint research projects on the energy transition and hydrogen, space, AI, and research security.

On the 29th of February 2024, the Franco-British Joint Committee for Science and Technology was held in London. Following this high-level dialogue, a budget was made available, respectively by the French and British governments, to finance joint research projects on the following four themes, defined as priorities by both countries:

• The energy transition and hydrogen;
• Space and Earth observation;
• Artificial intelligence, including ethics;
• Research security.

The objective of this funding is to foster excellent scientific and technological collaboration between both countries. Therefore, this call is for Franco-British projects in one of the four priority topics. Applications should be submitted by the French teams. Since the funds in this Sophie Germain call are provided by the French government, only French researchers will receive them. British researchers will have to apply to the British call, which will be launched separately from this one.
The funding available for each project can go up to €50,000. Funding will be provided in a single transfer based on the budget proposal and in the few weeks following the end of the selection phase. The funding may be used in the year following allocation and after this period has lapsed.
Applications should be submitted to the address info@ambascience.co.uk by July 17, 2025. The announcement of the successful projects is planned the end of September.
The first call received 29 application, of which 13 were awarded funding.

Lung cancer is the leading cause of cancer-related mortality in France, with over 30,000 deaths annually. Immunotherapy, which stimulates the immune response against tumor cells, offers tremendous hope for combating the disease. Unfortunately, only about half of eligible patients respond to this treatment, and it remains challenging to identify responders in advance to administer the most appropriate therapy from the outset.

Three researchers from Pr[AI]rie — Emmanuel Barillot (Institut Curie-INSERM), Thomas Walter (Mines ParisTech), and Irène Buvat (INSERM-Institut Curie) — along with a pneumooncologist (Nicolas Girard, Institut Curie), have been working together to improve patient care. Their approach integrates all available information, including clinical data, MRI and CT imaging, anatomical pathology (tumor slice images), and genomics (gene mutations and expression).

The initial results, obtained during the PhD of Nicolas Captier (Institut Curie), a young PRAIRIE researcher, and published in the journal Nature Communications, combine molecular, cellular, tissue-level, and overall patient data into a statistical learning model to predict patient response to immunotherapy. The project is funded by ARC (via the SIGN’IT call for proposals) and the Pr[AI]rie Institute.

This global recognition highlights individuals whose research publications rank in the top 1% of citations by field and publication year on the Web of Science index.
