通过RLHF技术,ChatGPT可以在与人类进行对话的同时不断优化模型的生成能力,并且实现与人类更加自然的对话交互。这种技术的引入使得ChatGPT在实际使用中能够不断改进,更好地满足用户的需求。 ChatGPT的原理包括PT、SFT和RLHF三个方面。通过这些技术的综合应用,ChatGPT可以实现高质量、流畅易读、结构合理的对话生成,为用户...
3. 对齐(RLHF) 让语言模型学习到人类的偏好,另模型的输出更符合人类习惯。分为两部分: 基于有监督微调模型基础上创建一个reward model(RM)模型; 基于RM模型使用PPO/DPO算法微调SFT模型,返回最佳response。 3.1 奖励模型 RM 该阶段是RHLF的第一个阶段,训练得到一个rm模型用于rl阶段的模型打分,其结构格式如下: ...
