PTGPO: Prefix Tree Group Policy Optimization

Ruolin Chen, Yang Li, Jihang Wang +4

Training language agents on long-horizon interactive tasks is challenging because sparse terminal rewards provide weak credit signals for intermediate actions. Existing group-based…

Regularity and compactness theory of stable free-boundary minimal hypersurfaces

Costante Bellettini, Martin Man-chun Li, Davide Parise +1

We establish the free-boundary version of Schoen-Simon's regularity and compactness theory for stable minimal hypersurfaces in a complete -dimensional Riemannian manifold-wi…

ProUIE: A Macro-to-Micro Progressive Learning Method for LLM-based Universal Information Extraction

Wenda Liu, Zhigang Song, Shuai Nie +11

LLM-based universal information extraction (UIE) methods often rely on additional information beyond the original training data, which increases training complexity yet often yield…

From Imitation to Discrimination: Toward A Generalized Curriculum Advantage Mechanism Enhancing Cross-Domain Reasoning Tasks

Changpeng Yang, Jinyang Wu, Yuchen Liu +9

Reinforcement learning has emerged as a paradigm for post-training large language models, boosting their reasoning capabilities. Such approaches compute an advantage value for each…
