Reinforcement Learning, RLHF, & DPO Explained

Learn how Reinforcement Learning from Human Feedback (RLHF) actually works and why Direct Preference Optimization (DPO) and Kahneman-Tversky Optimization (KTO) are changing the game. This video doesn't go deep on math. Instead, I provide a high-level overview of each technique to help you make practical decisions about where to focus your time and energy. 0:52 The Idea of Reinforcement Learning 1:55 Reinforcement Learning from Human Feedback (RLHF) 4:21 RLHF in a Nutshell 5:06 RLHF Variations 6:11 Challenges with RLHF 7:02 Direct Preference Optimization (DPO) 7:47 Preferences Dataset Example…
