arXiv:2606.06673v1 Announce Type: new Abstract: Sparse rewards and heterogeneous task sequences remain persistent challenges in Reinforcement Learning (RL), often resulting in slow convergence, weak generalization, and inefficient exploration. We propose Uncertainty-Aware LLM-Guided Policy Shaping (ULPS), a novel framework that integrates a calibrated Large Language Model (LLM) into the RL training loop to provide structured, uncertainty-modulated behavioral guidance. ULPS employs an A*-based oracle to synthesize optimal symbolic trajectories, which are used to fine-tune a BERT-based language
The increasing sophistication and capabilities of large language models are enabling their integration into more complex and uncertainty-aware control systems for AI, addressing long-standing challenges in reinforcement learning.
This development could significantly advance the capabilities of autonomous AI systems, enabling them to operate more efficiently and robustly in real-world environments with sparse rewards and diverse tasks.
The ability to provide structured, uncertainty-modulated guidance from LLMs changes how reinforcement learning agents explore and converge, potentially accelerating development of more generalizable AI.
