AReaL-DTA: Dynamic Tree Attention for Efficient Reinforcement Learning of Large Language Models

ICML 2026poster

Reinforcement learning (RL) based post-training for large language models (LLMs) is computationally expensive, as it generates many rollout sequences that could frequently share long token prefixes. Existing RL frameworks usually process these sequences independently, repeatedly recomputing identica…

SmartAgent: Chain-of-User-Thought for Embodied Personalized Agent in Cyber World

AAAI 2026technical

Recent advances in embodied agents with multimodal perception and reasoning capabilities based on large vision-language models (LVLMs), excel in autonomously interacting either real or cyber worlds, helping people make intelligent decisions in complex environments. However, the current works are nor

Generative Psycho-Lexical Approach for Constructing Value Systems in Large Language Models

ACL 2025long

Values are core drivers of individual and collective perception, cognition, and behavior. Value systems, such as Schwartz’s Theory of Basic Human Values, delineate the hierarchy and interplay among these values, enabling cross-disciplinary investigations into decision-making and societal dynamics. R…

3D Focusing-and-Matching Network for Multi-Instance Point Cloud Registration

NeurIPS 2024poster

Multi-instance point cloud registration aims to estimate the pose of all instances of a model point cloud in the whole scene. Existing methods all adopt the strategy of first obtaining the global correspondence and then clustering to obtain the pose of each instance. However, due to the cluttered an…
