- Location: Exhibit Hall C, D, E — Poster #304
- More Info: https://t.co/xCqSRiqMAB
Hope to see you there—looking forward to meeting researchers working on #ReinforcementLearning and #Planning!

[jshan @jisu_han__]

I’ll be presenting at #NeurIPS2025 Spotlight in San Diego next week!

Our work explores how value learning can remain stable and performant in long-horizon tasks by introducing temporal abstraction directly into the temporal-difference learning process.

If you’re interested in offline RL, goal-conditioned agents, or temporally abstract reasoning, I’d be glad to connect.

- Poster Title: Option-aware Temporally Abstracted Value for Offline Goal-Conditioned Reinforcement Learning
- Session Time: Fri, Dec 5 — 11 a.m. to 2 p.m. PST

@jiazhi_yang2024 @VilleKuosmanen +1 I’m also curious

🦾 Want home robots that manipulate everyday objects?
They should topple, roll, slide—not just grasp.

But current non‑prehensile policy fails in diverse envs (stair, cabinet).

3/ Real‑world performance
Evaluated on 9 real domains with novel objects: 78.9 % success rate despite training entirely in sim 📦🤖

Detailed evaluation in the paper.

@iScienceLuvr Yes please! I would like to join

Code & benchmark open-sourcing soon!

This work wouldn't have been possible without amazing collaborators:
Yoonyoung Cho, @Junhyekh, Jisu Han, and Beomjoon Kim.

@XingdongZ @philfung @huggingface @LeRobotHF Sure! 👍

[jshan @jisu_han__]

Just joined the LeRobot Hackathon Seoul district— and honestly, there’s something about building things with others who are genuinely curious and kind 🤖✨
Our team made a simple robot that can catch mosquitoes (world-wide enemy🦟)

How about your team?

WraspRobot, a bug swatter that made its way into the top 10 finalists! https://t.co/Bx43sIn1xc

@XingdongZ @philfung @huggingface @LeRobotHF Thanks, Xingdong! Our team was busy building everything from scratch, so we didn’t get much time to chat.
I was really impressed how your team trained on datasets for language practicality.
Would love to team up with you sometime, maybe at another hackathon or other chance! 😊

@Ash7Win10 @_1nF0rmed_ @LeRobotHF Thanks a lot!

[jshan @jisu_han__]

@partabot_ @huggingface @LeRobotHF Thanks for your kind comment! We considered multiple choice (e.g., companion robot) but we narrowed down to a robot that really mattered in our situation. Summer in Seoul is quite tough due to the fight with mosquitoes, so we all agreed to that topic and proceeded.
