RewardWeaver: Long-Horizon Interactive Learning for Language Agents via Self-Evolving Reward Adaptation

RewardWeaver is introduced, a self-evolving reward adaptation framework for language agents in long-horizon interaction that maintains a validated capability space in which the semantics of admitted Rubrics remain fixed, and closes the loop between policy optimization, task evaluation, failure attribution, and reward a...

PiERN: Token-Level Routing for Integrating High-Precision Computation and Reasoning

Physically-isolated Experts Routing Network (PiERN), an architecture that directs computation and reasoning at token level, thereby enabling iterative alternation within a single chain of thought, is proposed, offering an efficient, interpretable, and scalable paradigm for interfacing language models with scientific sy...

Application of Large Language Models and Natural Language Generation in Content Creation: A Retrieval-Augmented and Preference-Aligned Framework

Large language models (LLMs) have substantially advanced natural language generation (NLG), but high-quality content creation remains constrained by hallucination, limited controllability, retrieval noise, domain shift, and computational cost. This study proposes Retrieval-Augmented and Preference-Aligned Generation (R...
