Researchers have introduced a new method called Reward Modeling from Natural Language Human Feedback (RM-NLHF) to improve the training of Generative Reward Models (GRMs). Traditional methods using pairwise preference data can lead to GRMs learning to guess correct outcomes without genuine understanding, introducing noise into the training signal. RM-NLHF addresses this by using natural language critiques from humans to provide more accurate process reward signals, which are then used to train GRMs. The approach also includes a Meta Reward Model (MetaRM) to generalize from limited human critiques to larger datasets.
