LLM Training: RLHF and Its Alternatives

I frequently reference a process called Reinforcement Learning with Human Feedback (RLHF) when discussing LLMs, whether in the research news or tutorials. RLHF is an integral part of the modern LLM training pipeline due to its ability to incorporate human preferences into the optimization landscape, which can improve the model's helpfulness and safety.

LLM Training: RLHF and Its Alternatives Sebastian Raschka, PhD Sep 10, 2023 225 10 15 Share I frequently reference a process called Reinforcement Learning with Human Feedback (RLHF) when discussing LLMs, whether in the research news or tutorials. RLHF is an integral part of the modern LLM training pipeline due to its ability to incorporate human preferences into the optimization landscape, which can improve the model's helpfulness and safety. In this article, I will break down RLHF in a step-by-step manner to provide a reference for understanding its central idea and importance. Following up o
