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.
Jean Ponce directeur délégué de PR[AI]RIE-PSAI, professeur à l’École normale supérieure-PSL, professeur à New York University, s’est prêté au jeu du talk-show de Micode sur Underscore_ ! Une interview riche et accessible sur la vision par ordinateur.

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.
Jean Ponce directeur délégué de PR[AI]RIE-PSAI, professeur à l’École normale supérieure-PSL, professeur à New York University, à l’honneur dans un documentaire de France Télévisions sur la robotique avec les jeunes chercheurs Guillaume Le Moing et Marguerite Petit Talamon.
Depuis quarante ans, on nous promet des voitures automatiques. Les femmes et les hommes se laisseront conduire par la machine et pourront ainsi penser à autre chose – ou ne plus penser à rien. Mais dans ce monde à venir, faut-il vraiment laisser le volant à la technique ?
Ce documentaire “Pilotes automatiques” fait partie d’une série “Ecce Robots” de 4 épisodes proposée par Florent Muller, Frédéric Capron et Gaël Pouvreau.

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 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.

On June 12, 2025, the launch of PR[AI]RIE–PSAI marked a key moment for the future of artificial intelligence in France. Held at PariSanté Campus, the event brought together leading researchers, industry partners, students and innovators for a day rich in insights, exchanges and forward-looking perspectives.
Throughout the evening, participants also had the opportunity to visit a demonstration space showcasing ongoing research projects, startup initiatives, and the work of young researchers from PR[AI]RIE–PSAI and its partner institutions. The atmosphere was both dynamic and collaborative, reflecting our core values: interdisciplinarity, innovation, and openness.
This project would not have seen the light of day without the collective commitment of our partners: PSL University, Paris Cité University, CNRS, Inria, and l’Institut Pasteur.

A huge thank you to them for their trust, expertise, and commitment!
The PR[AI]RIE-PSAI adventure is only just beginning!

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.

The European Research Council (ERC) has awarded Justin Carpenter, Pr[AI]rie chair, a prestigious ERC Starting Grant grant to advance the development of truly autonomous robots.
Justin Carpenter has received an ERC grant to support his research on autonomous robots. Today, robotic systems work very well in factories because they evolve in highly controlled environments in which robots are required to perform the same task over and over again. However, getting these robots to interact with humans or complex environments remains impossible. Justin Carpentier aims to help robots move around and interact with their environments without human help, enhancing robot autonomy globally. The grant will allow him to explore new algorithms and machine-learning methods, which will help robots become more agile and adaptable.
This research could impact many industrial and societal domains, from manufacturing to healthcare. Read more here.

Pr[AI]rie researchers Tristan Cazenave and Quentin Cohen-Solal have once again achieved remarkable success at the 2024 Computer Olympiad, winning 11 gold medals!
Their achievement this year follows a record-breaking performance in 2023, where they won 16 gold medals, surpassing their previous record from 2021. This brings their total to an incredible 48 gold medals since their debut at the Olympiad in 2020!
Cazenave and Cohen-Solal have excelled in a variety of games, including Amazons, Hex, Breakthrough, and Canadian Draughts, thanks to their unique AI system. What sets their approach apart is the innovative Deep Reinforcement Learning system they developed, which diverges from standard methods like AlphaZero. Their system excels in search algorithms and the generation of training data, leading to unprecedented success across many different games.
Their record-breaking performance is a milestone that will be difficult to surpass, setting a new standard for future competitors.
Full results from the Computer Olympiad are available here.
