A Control Framework With Tactile Diffusion Policy and Variable Impedance for Unknown Surface Tracking

RA-L 2026

Precise position tracking and compliant interaction between robots and unstructured environments have always been a research hotspot, particularly in unknown surface tracking tasks. Traditional approaches typically rely on force sensor data to estimate surface normals, but suffer from certain estima

How do LLMs’ Preferences Affect Event Argument Extraction? CAT: Addressing Preference Traps in Unsupervised EAE

ACL 2025finding

Large Language Models (LLMs) have significantly improved the performance of unsupervised Event Argument Extraction (EAE) tasks. However, LLMs’ inherent preferences severely hinder their effectiveness in EAE, leading to what we term preference traps, namely, the Prior Knowledge Trap, the Sycophancy H…

Towards Foundational Models for Molecular Learning on Large-Scale Multi-Task Datasets

ICLR 2024poster

Recently, pre-trained foundation models have enabled significant advancements in multiple fields. In molecular machine learning, however, where datasets are often hand-curated, and hence typically small, the lack of datasets with labeled features, and codebases to manage those datasets, has hindered…
