🚨 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.

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...
Reformist Reinforcement Learning
What if we just begin and end with policy gradient?

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!

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.
Very proud to have contributed to this work, and very happy to have learnt a lot about votes, choices, and agents!
Marc Lanctot@sharky6000.bsky.social · last yr.Looking for a principled evaluation method for ranking of *general* agents or models, i.e. that get evaluated across a myriad of different tasks? I’m delighted to tell you about our new paper, Soft Condorcet Optimization (SCO) for Ranking of General Agents, to be presented at AAMAS 2025! 🧵 1/N
📣 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:

🚀 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 🧵👇

Claimed solution for the moving sofa problem? It looks intense, I hope it's correct arxiv.org/abs/2411.19826
Optimality of Gerver's Sofa
We resolve the moving sofa problem by showing that Gerver's construction with 18 curve sections attains the maximum area $2.2195\cdots$.

![Theorem. If $n$ is an integer and $n^2$ is even, then $n$ is itself even.
Proof. Contrapositives are for cowards, so assume $n$ is an integer and $n^2$ is even. Then $n^2=2k$ for some integer $k$, and thus $n^2-2k=0$. Behold:
\[ n = n + (n^2-2k) = n(n+1)-2k. \]
Both $n(n+1)$ and $2k$ are even, so $n$ is even.
