Reinforcement Learning from Human Feedback (RLHF)

Overview

Learn how to make GenAI models truly reflect human values while gaining hands-on experience with advanced LLMs.

Combine the efficiency of Generative AI with the understanding of human expertise in this course on Reinforcement Learning from Human Feedback. You’ll learn how to make GenAI models truly reflect human values and preferences while getting hands-on experience with LLMs. You’ll also navigate the complexities of reward models and learn how to build upon LLMs to produce AI that not only learns but also adapts to real-world scenarios.

Syllabus

Foundational Concepts

This chapter introduces the basics of Reinforcement Learning with Human Feedback (RLHF), a technique that uses human input to help AI models learn more effectively. Get started with RLHF by understanding how it differs from traditional reinforcement learning and why human feedback can enhance AI performance in various domains.

Gathering Human Feedback

Discover how to set up systems for gathering human feedback in this Chapter. Learn best practices for collecting high-quality data, from pairwise comparisons to uncertainty sampling, and explore strategies for enhancing your data collection.

Tuning Models with Human Feedback

In this Chapter, you'll get into the core of Reinforcement Learning from Human Feedback training. This includes exploring fine-tuning with PPO, techniques to train efficiently, and handling potential divergences from your metrics' objectives.

Model Evaluation

Explore key techniques for assessing and improving model performance in this last Chapter of Reinforcement Learning from Human Feedback (RLHF): from fine-tuning metrics to incorporating diverse feedback sources, you'll be provided with a comprehensive toolkit to refine your models effectively.
