Learning Dexterous Manipulation Skills from Imperfect Simulations

ICRA 2026poster

Reinforcement learning and sim-to-real transfer have made significant progress in dexterous manipulation. However, progress remains limited by the difficulty of simulating complex contact dynamics and multisensory signals, especially tactile feedback. In this work, we propose DexScrew, a sim-to-real…

MomaGraph: State-Aware Unified Scene Graphs with Vision-Language Models for Embodied Task Planning

ICLR 2026oral

Mobile manipulators in households must both navigate and manipulate. This requires a compact, semantically rich scene representation that captures where objects are, how they function, and which parts are actionable. Scene graphs are a natural choice, yet prior work often separates spatial and funct…

Do What? Teaching Vision-Language-Action Models to Reject the Impossible

EMNLP 2025

Recently, Vision-Language-Action (VLA) models have demonstrated strong performance on a range of robotic tasks. These models rely on multimodal inputs, with language instructions playing a crucial role-not only in predicting actions, but also in robustly interpreting user intent, even when the reque

LLaMP: Large Language Model Made Powerful for High-fidelity Materials Knowledge Retrieval

EMNLP 2025

Materials science research requires multi-step reasoning and precise material informatics retrieval, where minor errors can propagate into significant failures in downstream experiments. Despite their general success, Large Language Models (LLMs) often struggle with hallucinations, handling domain-s

A StrongREJECT for Empty Jailbreaks

NeurIPS 2024poster

Most jailbreak papers claim the jailbreaks they propose are highly effective, often boasting near-100% attack success rates. However, it is perhaps more common than not for jailbreak developers to substantially exaggerate the effectiveness of their jailbreaks. We suggest this problem arises because…
