Very excited to start sharing some of the work we have been doing at Amazon FAR. In this work we present OmniRetarget, which can generate high-quality interaction-preserving data from human motions for learning complex humanoid skills. High-quality re-targeting really helps

It's almost time for #CoRL 2025! A reminder that we're hosting the Data in Robotics workshop this Saturday Sept 27th. We have a packed schedule and are also attempting to livestream the event for those who can't attend in person.

At @RL_Conference๐Ÿ, I'm presenting a talk and a poster on Aug 6, Track 1: Reinforcement Learning Algorithms. We find that Deterministic Policy Gradient methods like TD3 often get stuck at local optima under complex Q-functions, and propose a novel actor architecture! ๐Ÿงต

I've been historically bearish on skill-based RL and @Jesse_Y_Zhang consistently shows me I'm probably wrong. Come check out EXTRACT at 1600 at @corl_conf (poster #11) to see him yank semantically meaningful skills out offline data by leveraging PTLMs. https://t.co/BddE1rsvXr

Most reinforcement learning (RL) methods focus on learning optimal policies over low-level action spaces. While these methods can perform well in their training environments, they lack the...

This work was guided by Jesse's co-advisor's @ebiyik_ and @JosephLim_AI, but I think we all agree that Jesse is effectively running his own little lab. If you're thinking about hiring a postdoc in the area of RL for robotics, Jesse comes a ton of insight and mentoring experience!

At #RSS2023 this week w/ some of my (ex-)students from CLVR (@YoungwoonLee @MinhoHeo @doohyun22 @sungj1026 ). Excited to meet about topics on robot learning, RL, physical reasoning, long-horizon manipulation, etc. + Recruiting (intโ€™l & domestic) students. Plz come and say hi!

Can robots be farsighted? We introduce SkiMo (Skill + Model-based RL), which allows more accurate and efficient long-horizon planning through temporal abstraction. SkiMo learns temporally-extended, sparse-reward tasks with 5x fewer samples! ๐Ÿงต๐Ÿ‘‡
