Researchers have demonstrated a method for training and analyzing language models using Reinforcement Learning from Human Feedback (RLHF). The process involves using the TRLX library for RLHF fine-tuning and TransformerLens for mechanistic interpretability. This approach was used to fine-tune a GPT-2 model to generate negatively biased movie reviews and then analyze the model to identify specific network regions responsible for this behavior. AI
