New EnGRICH framework enhances LLM reward models with human critique generalization

Researchers have developed EnGRICH, a new framework designed to improve generative reward models (GRMs) used in optimizing large language models. GRMs provide detailed critiques alongside preference judgments, but their reliability is crucial. EnGRICH incorporates a "MetaCritic" trained on scarce human critiques to construct rubrics and evaluate the quality of generated critiques. This approach allows the GRM to generalize evaluative criteria learned from human feedback to larger datasets that only provide outcome-based preferences, leading to improved performance across seven reward-model benchmarks.
