arXiv:2607.03248v1 Announce Type: cross Abstract: The alignment of large language models with human preferences is commonly achieved through Reinforcement Learning from Human Feedback or Direct Preference Optimization. However, these methods are vulnerable to the significant noise prevalent in real-world preference datasets. To address this critical issue, we present a theoretical framework for unbiased alignment, introducing the Unbiased Reward Model (URM) loss and the Unbiased Direct Preference Optimization (UDPO) loss. By mathematically correcting the distortion induced by preference noise,
The proliferation of Large Language Models has amplified the need for robust alignment methods, while the increasing scale of human feedback data highlights the problem of noise in preference datasets.
Improving the reliability of AI alignment processes directly impacts the safety, fairness, and utility of advanced AI systems, influencing their societal integration and regulatory frameworks.
The proposed URM and UDPO losses offer a theoretical and practical path to more robust LLM alignment by systematically mitigating noise in human preference data.

AI models become more aligned with human intentions, leading to fewer undesirable outputs.
Increased trust in AI systems could accelerate their adoption in sensitive applications.
Reduced 'hallucination' and bias in LLMs could necessitate a re-evaluation of established compliance and ethical guidelines for AI.
