DexDeform: Dexterous Deformable Object Manipulation with Human Demonstrations and Differentiable Physics

ICLR 2023poster

In this work, we aim to learn dexterous manipulation of deformable objects using multi-fingered hands. Reinforcement learning approaches for dexterous rigid object manipulation would struggle in this setting due to the complexity of physics interaction with deformable objects. At the same time, prev…

Phrase-Level Temporal Relationship Mining for Temporal Sentence Localization

AAAI 2023technical

In this paper, we address the problem of video temporal sentence localization, which aims to localize a target moment from videos according to a given language query. We observe that existing models suffer from a sheer performance drop when dealing with simple phrases contained in the sentence. It r…

Contact Points Discovery for Soft-Body Manipulations with Differentiable Physics

ICLR 2022spotlight

Differentiable physics has recently been shown as a powerful tool for solving soft-body manipulation tasks. However, the differentiable physics solver often gets stuck when the initial contact points of the end effectors are sub-optimal or when performing multi-stage tasks that require contact point…
