Direct Preference Optimization (DPO)

31 Oct 2024

🚧 Work in progress…

This article will cover Direct Preference Optimization (DPO), a simpler alternative to RLHF that directly optimizes language models using preference data without requiring a separate reward model.

Topics to cover:

• Limitations of RLHF and PPO
• DPO formulation and theoretical foundation
• Comparison with PPO-based RLHF
• Implementation and practical considerations
