A Regret Minimization Framework on Preference Learning in Large Language Models
Researchers have introduced a new framework called Regret-based Preference Optimization (RePO) for training large language models using human feedback. RePO reframes the process from reward maximization to regret minimization, modeling human preferences based on anticipated outcomes and counterfactual comparisons. Experiments on mathematical reasoning and human preference datasets show that RePO offers improved performance and better human alignment. AI
