We've lost an absolute giant today. RIP Dimitri Bertsekas. His probability and optimization books got me through my masters. Massive loss for the MIT community and the field.

[F. Güney @ftm_guney]

interested in 3D vision, motion, driving, or robotics? consider applying to our graduate programs. the fall deadline is May, 15.

we do our best to provide a research environment where students can reach their potential and publish in top-tier AI venues.
we regularly collaborate with leading AI labs worldwide and offer EU-level scholarships (+dorm/housing support), solid GPU resources (a decent local cluster + access to supercomputers like Leonardo and MareNostrum), and a fun, supportive lab environment :)

I work on the JAX team. If you're new to the field ignore this bait. The things you should focus on are understanding the math and how to program accelerators - really master your hardware and your methods. We try to make a great tool but don't obsess over tools early.

Swiss AI Visiting PhD Program at EPFL. Deadline Feb 28.

"The program provides a fellowship contribution of CHF 2,500 ($3200) per month, access to the Alps supercomputer, and eligibility for a post-visit continuation grant of up to 50k GPU hours. The call is open to PhD students enrolled outside Switzerland, with applications supported by EPFL PIs contributing to the Swiss AI Initiative. The application closes on February 28."

A whole lot of BS political views basically amount to assuming that life in our hard won civilisations is just the way things are, and that you can simply remove the foundations.

Only a society protected by vaccines produces anti-vaxxers. Only a society with a strong military produces pacifists. Only a society with large scale industrial farming produces organic foodies. Only societies with cheap energy produce degrowthers.

You don’t get to enjoy the ends whilst condemning the means, and still be taken seriously.

[Eugene Vinitsky 🦋 @EugeneVinitsky]

You've got a couple of GPUs and a desire to build a self-driving car from scratch. How can you turn those GPUs and self-play training into an incredible looking agent? Come to W-821 at 4:30 in B2-B3 to learn from @Mdjxjxnsk @tw_killian @ozansener

Hiring researchers and engineers for a stealth, applied research company with a focus on RL x foundation models. Folks on the team already are leading RL / learning researchers. If you think you'd be good at the research needed to get things working in practice, email me

We've built a simulated driving agent that we trained on 1.6 billion km of driving with no human data.
It is SOTA on every planning benchmark we tried.
In self-play, it goes 20 years between collisions.

[Bernhard Jaeger @bern_jaeger]

https://t.co/2rFrN5G2n6
Awesome planning results by Vladlen Koltun's new lab (@Mdjxjxnsk @BrodyHuval @petrenko_ai @EugeneVinitsky @tw_killian @ozansener and others) that everyone working on driving should read.
Lots of details are in the Appendix.

[Edward Hughes @edwardfhughes]

Incredibly exciting work! https://t.co/aJEGtpF9eL. Cooperative, safe, driving can arise at scale from self-play training without human data, just as my group saw in Overcooked a few years ago. Caveat: in simulation. Bravo @EugeneVinitsky and coauthors!

[Aleksei Petrenko @petrenko_ai]

Excited to share our new pre-print https://t.co/FtT3hkHKeG

We train a digital agent that solves diverse day-to-day tasks from the AppWorld benchmark by interacting with its stateful environment using API calls. AppWorld is hard! The previous best open-weight agent (Llama 3 70B) reached only a 7% success rate on the hardest test split. Our RL algorithm, LOOP - a PPO variant with Monte Carlo baselines - achieves a 45.7% success rate, 24% over the base Qwen 2.5 32B, and 9% higher than a much larger OpenAI o1.
