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…

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

LISAt: Language-Instructed Segmentation Assistant for Satellite Imagery

NeurIPS 2025poster

Segmentation models can recognize a pre-defined set of objects in images. However, segmentation models capable of "reasoning" over complex user queries that implicitly refer to multiple objects of interest remain underexplored, especially in the geospatial domain. Recent advances in "reasoning segme…
