DPO (Direct Preference Optimization)
A training technique that aligns language models with human preferences without needing a separate reward model.
In depth
A training technique that aligns language models with human preferences without needing a separate reward model. Unlike RLHF, which trains a reward model first and then optimizes against it, DPO directly optimizes the language model using pairs of preferred and dispreferred outputs. DPO is simpler to implement, more stable to train, and has become a popular alternative to RLHF for model alignment.
Example
Unlike RLHF, which trains a reward model first and then optimizes against it, DPO directly optimizes the language model using pairs of preferred and dispreferred outputs.
