Directional Preference Alignment and RLHF Pass@k Performance on MBPP from 7B to 70B

Abstract

Abstract: This report synthesises findings from 11 peer-reviewed papers addressing the following research question: How does the pass@k metric for Directional Preference Alignment compare to RLHF on the MBPP benchmark when scaling model parameters from 7B to 70B. Fine-grained control over large language models (LLMs) remains a significant challenge, hindering their adaptability to diverse user needs. While Reinforcement Learning from Human Feedback (RLHF) shows promise in aligning LLMs, its reliance on scalar rewards often limits its. 13 claims were extracted from source literature; 3 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 5.2/10. This report is a machine-generated literature synthesis and does not constitute original research.
