Researchers have developed a new method called the Maximum Entropy Blackwell Winner (MaxEntBW) to address intransitive preferences in multi-objective fine-tuning of large language models. This approach, implemented in the PROSPER algorithm, directly handles multiple objectives without needing to combine them into a single metric. Experiments show PROSPER outperforms existing methods on instruction following and chat benchmarks, with trained model checkpoints released at 7B and 3B parameter scales. AI
