UnverifiedThe essence of DPO is to make the model learn to judge which response is better, and it does not directly constrain the model to autonomously generate that better response.78% 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76% 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76% 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.76% similarUnverifiedDPO隐含假设偏好数据服从Bradley-Terry模型，当偏好具有非传递性时可能产生不一致行为75% similar
