UnverifiedDPO uses the log-probability difference between the policy model and the reference model as an implicit reward, enabling the model to increase the generation probability of better responses while staying close to the reference model.78% similarUnverifiedDPO方法利用奖励函数与最优策略之间的解析关系，将RL问题转化为更简单的监督学习问题77% similarUnverified微调后的模型可通过DPO（直接偏好优化）进行对齐，确保输出符合业务安全规范74% similarUnverifiedDPO的核心洞见是语言模型本身可视为隐式奖励函数，因此可直接对偏好对进行对比学习，绕过显式奖励模型73% similarVerifiedDPO (Direct Preference Optimization) is an alignment method proposed in 2023 that can skip reward model training and directly optimize the policy model from human preference data.72% similar
