Preference Consistency Matters: Enhancing Preference Learning in Language Models with Automated Self-Curation of Training Corpora

Abstract

Ambiguity in language presents challenges in developing more enhanced language models, particularly in preference learning, where variability among annotators results in inconsistently annotated datasets used for model alignment. To address this issue, we introduce a self-curation method that preprocesses annotated datasets by leveraging proxy models trained directly on these datasets. Our method enhances preference learning by automatically detecting and removing ambiguous annotations within the dataset. The proposed approach is validated through extensive experiments, demonstrating a marked improvement in performance across various instruction-following tasks. Our work provides a straightforward and reliable method to overcome annotation inconsistencies, serving as an initial step towards the development of more advanced preference learning techniques.
