Researchers have developed a new method called Selective Tie Learning to improve preference optimization in machine learning models. This technique aims to reduce the learning of spurious correlations by strategically incorporating "ties" – instances where two responses are equally preferred. The study derives theoretical optimal selection rules for these ties, particularly for log-linear policies, and proposes using the magnitude of a tie's implicit reward margin as a proxy for its corrective influence when exact calculations are infeasible. Experiments across various models, including large language models, demonstrate that these selection rules effectively reduce spurious reliance with fewer ties compared to uniform selection methods.
