DualEqui: A Dual-Space Hierarchical Equivariant Network for Large Biomolecules

NeurIPS 2025poster

Geometric graph neural networks (GNNs) that respect E(3) symmetries have achieved strong performance on small molecule modeling, but they face scalability and expressiveness challenges when applied to large biomolecules such as RNA and proteins. These systems require models that can simultaneously c…

Multi-Type Preference Learning: Empowering Preference-Based Reinforcement Learning with Equal Preferences

ICRA 2025

Preference-Based reinforcement learning (PBRL) learns directly from the preferences of human teachers regarding agent behaviors without needing meticulously designed reward functions. However, existing PBRL methods often learn primarily from explicit preferences, neglecting the possibility that teac

Robustness Inspired Graph Backdoor Defense

ICLR 2025oral

Graph Neural Networks (GNNs) have achieved promising results in tasks such as node classification and graph classification. However, recent studies reveal that GNNs are vulnerable to backdoor attacks, posing a significant threat to their real-world adoption. Despite initial efforts to defend against…

EEE-QA: Exploring Effective and Efficient Question-Answer Representations

COLING 2024main

Current approaches to question answering rely on pre-trained language models (PLMs) like RoBERTa. This work challenges the existing question-answer encoding convention and explores finer representations. We begin with testing various pooling methods compared to using the begin-of-sentence token as a…
