Maximizing Mutual Information Between Prompt and Response Improves LLM Performance With No Additional Data

Hyunji Nam, Haoran Li, Natasha Jaques

While post-training has successfully improved large language models (LLMs) across a variety of domains, these gains heavily rely on human-labeled data or external verifiers. Existi…

X-DiffVLA: X-Embodied Diffusion Action Heads for Vision-Language-Action Models

Boyu Li, Chaoyi Xu, Haoqi Yuan +5

Learning universal policies from cross-embodied data remains a fundamental challenge in robotics. Although Vision-Language-Action (VLA) models are pre-trained on large and diverse…

Can LLMs Time Travel? Enhancing Temporal Consistency in Legal Agentic Search through Reinforcement Learning

Wei Fan, Yining Zhou, Mufan Zhang +8

While large language models (LLMs) augmented with agentic search capabilities show promise for legal reasoning, they overlook a fundamental constraint that applicable law must matc…

SciCustom: A Framework for Custom Evaluation of Scientific Capabilities in Large Language Models

Yiyang Gu, Junwei Yang, Junyu Luo +15

Large language models (LLMs) are increasingly applied to scientific research, yet existing evaluations often fail to reflect the fine-grained capabilities required in practice. Mos…
