🚨 New paper: Introducing MIND (Monge Inception Distance) Everyone agrees that FID is broken, requires too many samples, slowing down evals. MIND requires 10x fewer samples, is more robust, faster to compute. Our new drop-in replacement for evaluating generative models. 🧵👇

Very happy to arrive in Tanger for AISTATS 2026, the conference with a palm tree in the logo 🌴 🌊 Let me know if you want to chat!

Today NeurIPS is announcing our official satellite event in Paris. After responding to the call from Ellis following the success of EurIPS in December, we are pleased to reach a new milestone by joining forces with the NeurIPS organizing committee for the 2026 edition.

Following the success of the EurIPS and NeurIPS-Mexico City pilots in 2025, we are thrilled to announce two official NeurIPS 2026 satellite events for this year! These will be held in Paris, France and Atlanta, USA, respectively, running alongside the main venue in Sydney, Australia.

🌴📊📈 - AISTATS 2026 workshops For the first time, AISTATS (May 2-5 in Tangier, Morocco) will have a day of workshops! Please submit your best work by Feb. 27th: - calibration-workshop.github.io - optimal-workshop26.github.io - causcale.github.io virtual.aistats.org/virtual/2026... 👇

🚨 🔬 PhD positions at Google DeepMind in France 🇫🇷 We are advertising Master Level Intern positions at Google DeepMind within our Frontier AI Unit. These could lead to co-advised PhD positions with Google DeepMind and French academic institutions. job-boards.greenhouse.io/deepmind/job...

Arrived #NeurIPS2025 ☀️ If you're interested in the interplay of Geometry, Topology, Algebra w/ Neuroscience & AI, I'll give 2 talks on Sunday: 🌐11:30am: The Algebra of Spatial Navigation (Groups & grid cells) 🍩1:30pm: Topological Deep Learning (Complexes & Graphs) More👇

Intersection of topics: super interesting research and one of the best feel-good movies of all time

In honor of the 39th AI Winter, I’m going to spend the week disentangling the culture and code of reinforcement learning. There may be ranting...

Thanks @ucsantabarbara.bsky.social for highlighting our #TIMEBestInvention of the Year award! tinyurl.com/4939bxu5 This strengthens our commitment to innovating for women's brain health with @ai-ucsb.bsky.social & @bowers-wbhi.bsky.social 🧠

Speaking of EurIPS: looking for coffee recommendations in Copenhagen (planning ahead of tomorrow morning)

Today is a day about three very cool things: trains, Europe, and ML! I'm on my way from Paris to Copenhagen, to attend my first EurIPS! Looking forward to it, reach out if you want to chat!

Nice to be at NeurIPS@Paris, and happy that Google DeepMind could support the organizers of this amazing event!

🚨AISTATS workshop proposals open! Big News: For the first time, there will be a day of workshops at #AISTATS 2026, in Tangier, Morocco 🌴🇲🇦 Quentin Berthet @qberthet.bsky.social and I are workshop chairs. virtual.aistats.org/Conferences/... Deadline: Oct 17, AOE

I will be attending #ICLR2025 in Singapore and #AISTATS2025 in Mai Khao over the next two weeks. Looking forward to meeting new people and learning about new things. Feel free to reach out if you want to talk about Google DeepMind.

ICML reviews are out

Very proud to have contributed to this work, and very happy to have learnt a lot about votes, choices, and agents!

📣 New preprint 📣 Learning Theory for Kernel Bilevel Optimization w/ @fareselkhoury.bsky.social E. Pauwels @michael-arbel.bsky.social We provide generalization error bounds for bilevel optimization problems where the inner objective is minimized over a RKHS. arxiv.org/abs/2502.08457

🚨 New paper on regression and classification! Adding to the discussion on using least-squares or cross-entropy, regression or classification formulations of supervised problems! A thread on how to bridge these problems:

I've got to say, the guy who accidentally became the Director of the FBI does 100% look like the guy who accidentally becomes the Director of the FBI in a mid-2000s comedy about a guy who accidentally becomes the Director of the FBI

🚀 Policy gradient methods like DeepSeek’s GRPO are great for finetuning LLMs via RLHF. But what happens when we swap autoregressive generation for discrete diffusion, a rising architecture promising faster & more controllable LLMs? Introducing SEPO ! 📑 arxiv.org/pdf/2502.01384 🧵👇

Contrapositives are for cowards. Behold.

Merci @lemonde.fr pour un joli résumé de mes aventures scientifiques et logiciels 📈📠 www.lemonde.fr/sciences/art... Beaucoup de messages qui me tiennent à cœur : travail d'équipe, logiciel libre, rigueur scientifique Merci aux collègues et amis qui ont témoigné, je suis ému de lire

Thrilled to be co-organizing NeurIPS in Paris at @sorbonne-universite.fr next week! 📑 100 papers from NeurIPS 2024. Nearly twice as many as in 2023! 🧑‍🎓 over 300 registered participants ✅ a local and sustainable alternative to flying to Vancouver. More info: neuripsinparis.github.io/neurips2024p...

Claimed solution for the moving sofa problem? It looks intense, I hope it's correct arxiv.org/abs/2411.19826

AISTATS reviews are out.

A big thanks to my co-authors Christian Borgelt, @tobiassutter.bsky.social @hildekuehne.bsky.social Oliver Deussen and Stefano Ermon. Also a shout-out to the authors of the methods we build on: @qberthet.bsky.social @mblondel.bsky.social @marcocuturi.bsky.social @bachfrancis.bsky.social ky.social

As an AC/SAC for too many conferences right now, I highly recommend people in these roles to gently nudge reviewers who don't reply after author rebuttal. People can be forgetful, or have busy lives but will often reply / update their scores when reminded to.
