Introduction and Overview of Reinforcement Learning for LMs

Reinforcement learning is discussed in the context of large language models (LMs). The podcast covers the application of reinforcement learning in the era of LMs, focusing on how it can help in adhering to instructions and specific use cases. It delves into the initial overview of reinforcement learning and its application to LMs, particularly in the context of RLHF (reinforcement learning human feedback), prompting, and more. The episode highlights the importance of reinforcement learning's role in guiding LMs to provide coherent and accurate responses.

We’re exploring Reinforcement Learning in the Era of LLMs this week with Claire Longo, Arize’s Head of Customer Success. Recent advancements in Large Language Models (LLMs) have garnered wide attention and led to successful products such as ChatGPT and GPT-4. Their proficiency in adhering to instructions and delivering harmless, helpful, and honest (3H) responses can largely be attributed to the technique of Reinforcement Learning from Human Feedback (RLHF). This week’s paper, aims to link the research in conventional RL to RL techniques used in LLM research and demystify this technique by discussing why, when, and how RL excels.
