4.1. Summarizing Reddit posts from human feedback Policies trained with human feedback are preferred to much larger supervised policies:基于人类反馈进行微调的模型,1.3B的效果即可超越12.9B的效果,而且随着模型规模的增加,效果会进一步提升 Controlling for summary length:由于我们的模型倾向于产生较长的摘要,这...
介绍了一种新的方法,称为Nash Learning from Human Feedback(NLHF),用于通过人工反馈来微调大型语言模型(LLM)。与传统的基于奖励模型的方法不同,NLHF采用了偏好模型,通过学习生成一系列优于竞争策略的回应来定义偏好模型的Nash均衡。为了实现这一目标,研究者提出了一种基于镜像下降原理的算法,称为Nash-MD。此外,还...
这个工作用到的RLHF(Reinforcement Learning from Human Feedback)是ChatGPT系列背后一个很重要的方法。如何把人类的偏好告诉生成式模型?传统的通过监督学习和最大化对数似然并不是一个好的方法。因为在摘要、翻译等任务中,可能同时有几个大相径庭的版本都是好的输出,而最大化对数似然只会迫使输出去接近训练集里的...

Reinforcement learning from human feedback (RLHF) has emerged as the main paradigm for aligning large language models (LLMs) with human preferences. Typically, RLHF involves the initial step of learning a reward model from human feedback, often expressed as preferences between pairs of text gener...
