Dataset Composition for RL Fine-Tuning in RLHF
A development team aims to fine-tune a language model to be 'helpful and harmless'—qualities that are nuanced and difficult to exemplify perfectly. They consider two strategies:
- Supervised Approach: Have human experts write ideal, 'gold-standard' responses to a wide range of prompts for the model to imitate.
- Preference-Based Approach: Have the model generate multiple responses to each prompt, and then have human experts rank these responses from best to worst.
What is the primary reason that the preference-based approach is often more effective for aligning a model with such complex human values?
