We argue for the epistemic and ethical advantages of pluralism in Reinforcement Learning from Human Feedback (RLHF) in the context of Large Language Models (LLMs). Drawing on social epistemology and pluralist philosophy of science, we suggest ways in which RHLF can be made more responsive to ...

“Using human feedback directly as a reward function is prohibitively expensive for RL systems that require hundreds or thousands of hours of experience,” state the authors of “Deep reinforcement learning from human preferences.” As a result, researchers came up with reinforcement learning ...

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...
📚 在本章中,我们将一同探索强化学习从人类反馈中学习(Reinforcement Learning from Human Feedback, RLHF)这一引人入胜且日益重要的领域。我们将从宏观视角出发,理解RLHF为何在当前人工智能(Artificial Intelligence, AI)的发展浪潮中扮演着关键角色,它试图解决什么核心问题,以及它的起源和发展历程。无论您是初学者...
