Super excited to share the last paper of my PhD: "Hallucination in World Models is Predictable and Preventable"✨ We train a 350M-param generative world model on a large dataset w/ 210 tasks and show that we can predict *when* hallucination happens and use that to fix it! 🧵1/n

TD-MPC2 just got ~5x faster! The update is available in a separate "speedups" branch at the moment and will be merged into main soon. Special thanks to @VincentMoens for his help with this!

New fun benchmark for RL researchers to stress test their algorithms! We release code + human driver data for imitation, and benchmark TD-MPC2 in a multi-track setting 🏎️💨

Besides reading cool papers, my Twitter account is mostly used for catching up @F1 news. Very excited about @LandoNorris 's great performance recently. Now we combine Formula Racing to AI research: The following video shows we train a Reinforcement Learning policy to drive a

New work led by @imgeorgiev! We show that TD-MPC2 world models can be used as differentiable simulators in a multi-task setting, and it even beats an *actual* differentiable simulator. Super fun collaboration and the results are really promising!

🔔New Paper - PWM: Policy Learning with Large World Models Joint work with @VarunGiridhar3 @ncklashansen @animesh_garg PWM is a multi-task RL method which solves 80 tasks across different embodiments in <10m per task using world models and first-order gradient optimization🧵
