Idea
EAG-RL platform improves clinical prediction accuracy by enhancing LLM reasoning on electronic health records for healthcare providers.
Research Paper
Core Innovation
This paper introduces EAG-RL, a novel two-stage training framework that integrates expert attention from specialized deep learning models to guide large language models' reasoning on EHR data. It uniquely combines expert-guided Monte Carlo Tree Search with reinforcement learning to improve reasoning ability, robustness, and generalization in clinical prediction tasks. This approach advances beyond prior work by explicitly aligning LLM attention with expert models for better EHR understanding.
