π Excited to share REPPO, a new on-policy RL agent!
TL;DR: Replace PPO with REPPO for fewer hyperparameter headaches and more robust training.
REPPO, led by @cvoelcker.bsky.social, will be presented at ICLR 2026. How does it work? π§΅π
Great resource!
This is specially important for people starting their research careers.
Getting to know different research communities is really important! Technical insight is crucial, but science is ultimately a social endeavor -- understanding and communicating to your peers is key.
As we in the US gather with our families this weekend, it's a good time to consider the ways that technology brings us togetherβbut also keeps us apart. In this blog post, I tell a story about how technology may have tended to increase social isolation.

Breaking: we release a fully synthetic generalist dataset for pretraining, SYNTH and two new SOTA reasoning models exclusively trained on it. Despite having seen only 200 billion tokens, Baguettotron is currently best-in-class in its size range. pleias.fr/blog/blogsyn...
Session this afternoon (in 30 minutes)!!
Poster 153 β see you there!
I wrote a notebook for a lecture/exercice on image generation with flow matching. The idea is to use FM to render images composed of simple shapes using their attributes (type, size, color, etc). Not super useful but fun and easy to train!

Comments welcome!
Oh nvm I read βour ICCV paperβ¦β haha
Are the results out? I see nothing in OpenReview :-(
For folks attending CVPR: is there a website where I can see the list of workshops, their location AND time? Day and time are empty when I access cvpr.thecvf.com/Conferences/...
I will be in Nashville until Saturday for CVPR'25 \o/
DM if you want to meet!

Honored to have been awarded at #Eurographics25 for our paper on #LipschitzPruning to speed-up SDF rendering!

Congrats to @wbrbr.bsky.social, M. Sanchez, @axelparis.bsky.social, T. Lambert, @tamyboubekeur.bsky.social, M. Paulin and T. Thonat!
I usually write a python script that prints some .npy file as tex a .tex table. It is also useful as an easy way to share results throughout the project, so I consider this as part of the codebase. I heard that people that are more serious about such practice use smth like github.com/JelteF/PyLaTeX
Comecei a fazer por causa disso e por causa do vim, mas atΓ© no overleaf Γ© vantagem
Eu n uso pra coisas que faço sozinho (anotaçáes, apresentaçáes, etc). Mas pra trabalho colaborativo é meio q obrigatório. Estudantes vão entrar em revolta se vc usar git hahaha
NeurIPS and SIGGRAPH Asia deadline are coming.
Make your life easier: read this thread.
Let's gooo!!! \o/
Probably my first time visiting Brazil for professional reasons :-)
What features did you find particularly useful?
I liked asking questions about the code base and the tab completion seems nice, but I've been getting unhelpful suggestions for all the "agentic" stuff.
By popular demand, we are extending #CVPR2025 coverage to Bluesky. Stay tuned!
Exciting news! MegaSAM code is outπ₯ & the updated Shape of Motion results with MegaSAM are really impressive! A year ago I didn't think we could make any progress on these videos: shape-of-motion.github.io/results.html
Huge congrats to everyone involved and the community π
*it
I understand the sentiment, but it is important for people to know that is currently does not reflect reviewer guidelines at CVPR: cvpr.thecvf.com/Conferences/...
β(β¦) you should include specific feedback on ways the authors can improve their papers.β
But is Meta indeed cancelling professional fact checking worldwide? Their response to the Brazilian supreme court inquiry said the dismissal of professional fact checking was exclusive to the US
Late to post, but excited to introduce CUT3R!
An online 3D reasoning framework for many 3D tasks directly from just RGB. For static or dynamic scenes. Video or image collections, all in one!
Project Page: cut3r.github.io
Code and Model: github.com/CUT3R/CUT3R
Those plots are so cool! \o/
Itβs a plugin for neovim that has some stuff similar to cursor; it is open source and you can configure it to use the model of your choice
I am using Avante + vim and I am pretty happy about it
ππ°οΈπWanna know which features are universal vs unique in your models and how to find them? Excited to share our preprint: "Universal Sparse Autoencoders: Interpretable Cross-Model Concept Alignment"!

New paper about pictures: I identify trends in geometric perspective in my own drawings and photos, and compare them to how the original scenes looked. I discuss what these trends might say about art history and vision science. Published in _Art & Perception_. #visionscience
