Je mettrai cette page à jour à la fin 2026 (en même temps qu'un bilan de l'organisation du satellite européen de NeurIPS). D'ailleurs elle n'est plus accessible en navigation depuis le reste de mon site web, car je n'en suis pas très content sous sa forme actuelle.

Nous avons environ 80% d'européens dans les inscrits pour l'instant (et environ 15% de nord-américains). Nous publierons un bilan carbone (y compris Scope 3) de la conférence NeurIPS Paris, qui permettra d'analyser l'impact carbone des déplacements des participants.

Results on Lean 4 theorem proving: → Higher policy entropy and better pass@k scaling than GRPO → Faster discovery of new Mathlib tactics → The two methods are complementary: GRPO initialized from a Feedback Distillation checkpoint outperforms both methods alone. → This works even with self-feedback.

This paper proposes Feedback Distillation, a self-distillation approach where we the model is trained to match its own distribution conditioned on feedback from an LLM (possibly itself) analyzing its failed attempts.

FAQ on NeurIPS Europe: NeurIPS Europe is an official NeurIPS 2026 satellite event taking place in Paris, France, alongside the main conference in Sydney and the other satellite event in Atlanta. NeurIPS authors can present their papers at any of the three locations, subject to space availability.

We are currently figuring out the logistical implementation of having three parallel NeurIPS events and adjusting the demand to the venue capacity. More details soon. But I am confident in saying that the system will not include publicly sharing at registration time who attends where.

I'm totally biased on this but I think it's wonderful that we now have official NeurIPS parallel satellite events. Parallelization was the trick that allowed us to scale to large data and models. It makes sense to try it for conferences as the community grows.

I love the #eurips initiative! But to live up to its potential, it should be accepted an official #neurips conference location (similar to Mexico City) and not just an addon! Then we would save C02, rather than adding to it!!! What can we do to achieve this?
