Hierarchical Reward Modeling for Fault Localization in Large Code Repositories

EMNLP 2025

Large Language Models (LLMs) exhibit significant potential in complex software engineering tasks, however, their fault localization capabilities within repository are constrained by inherent limitations in max context length. Although Test-Time Scaling (TTS) can generate multiple candidate solutions
