While it is intuitively clear that straighter trajectories should reduce discretization error when integrating an ODE (for instance, in flow matching), I could not find a precise bound. I therefore rewrote the proof of Cauchy-Lipschitz to make this explicit. github.com/gpeyre/Discr...

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.
🧵 New preprint! Towards Understanding Steering Strength w/ M. Taimeskhanov and D. Garreau
Activation steering is a popular way to control LLM behavior at inference. But how much should you steer? We provide the first theoretical analysis of the steering strength α.

This semester I have been given the chance to teach a course on "Deep Learning for Time Series" at @ipparis.bsky.social
If you're interested in the topics, have a look at rtavenar.github.io/x-dl4ts/
Repo has Typst code for the slides and Python code for the labs.
Feedback is very much welcome.
This year I'm teaching a new course on generative models for visual content (images, video, 3D, etc). It's mostly me rambling about recent papers, design choices I like/hate. The slides of the first lectures are here: davidpicard.github.io/teaching/

Openreview opened the door to continuous and major revisions that nobody has time to check properly.
I think that we should come back to short one pdf page replies to reviews. It would mean having decisions quicker so that we actually have time to work on papers before resubmitting them.
