ChatGPT: Reinforcement Learning from Human Feedback (RLHF)

Overview

The ChatGPT chatbot, built on GPT’s transformer architecture, utilizes Reinforcement Learning from Human Feedback (RLHF) to generate helpful, truthful responses in line with human preferences.

Challenges and Solutions

RLHF streamlines data collection by training a language model to produce responses that maximize learned rewards. However, reward hacking and skewed human preference data pose challenges. Recent research from NVIDIA and the University of Maryland has proposed the ODIN technique to mitigate reward hacking and improve response quality.
