Co-rewarding: Stable Self-supervised RL for Eliciting Reasoning in Large Language Models

ICLR 2026poster

Although reinforcement learning with verifiable rewards (RLVR) shows promise in improving the reasoning ability of large language models (LLMs), the scaling up dilemma remains due to the reliance on human-annotated labels especially for complex tasks. Recent self-rewarding methods provide a label-fr…

Towards Understanding Valuable Preference Data for Large Language Model Alignment

ICLR 2026poster

Large language model (LLM) alignment is typically achieved through learning from human preference comparisons, making the quality of preference data critical to its success. Existing studies often pre-process raw training datasets to identify valuable preference pairs using external reward models or…

Fast and Accurate Blind Flexible Docking

ICLR 2025poster

Molecular docking that predicts the bound structures of small molecules (ligands) to their protein targets, plays a vital role in drug discovery. However, existing docking methods often face limitations: they either overlook crucial structural changes by assuming protein rigidity or suffer from low…
