For various reasons, e.g., personal bias, context ambiguity, lack of training, etc, human annotators may give incorrect or inconsistent preference labels. To tackle this challenge, we propose a robust RLHF approach -- $R^3M$, which models the potentially corrupted preference label as sparse outliers. Accordingly, we formulate the robust reward learning as an…

arXiv:2406.15363v1 Announce Type: new Abstract: Large Language Models (LLMs) have demonstrated impressive and diverse abilities that can benefit various domains, such as zero and few-shot information extraction from clinical text without domain-specific training. However, for the ICD coding task, they often hallucinate key details and produce high recall but low precision results due to the high-dimensional and skewed distribution of the ICD codes. Existing LLM-based methods fail to account for the complex and dynamic interactions among the human agents involved in coding, such as patients, physicians, and coders, and they lack interpretability and reliability. In this paper, we present a…
