arXiv:2509.10515v1 Announce Type: cross Abstract: Offline preference optimization methods are efficient for large language models (LLMs) alignment. Direct Preference optimization (DPO)-like learning, one of the most popular approaches, stands out for its efficiency in reward modeling. However, these methods typically follow the convention to use Bradley-Terry (BT) reward modeling that faces several critical assumptions, including the requirement for pairwise training data, model distribution shifting, human rationality assumption, etc. To address these limitations, we propose a general framewo
The rapid advancement and widespread adoption of large language models (LLMs) necessitate more efficient and robust alignment methods, pushing researchers to refine current optimization techniques.
Improving LLM alignment efficiency and robustness is crucial for developing safer, more reliable, and universally applicable AI systems, impacting their real-world utility and trustworthiness.
This research introduces a framework that could overcome key limitations of current preference optimization methods like DPO, potentially making LLM alignment less reliant on specific data assumptions and more adaptable.
