* **Preference datasets**: These datasets typically contain several answers with some kind of ranking, which makes them more difficult to produce than instruction datasets.
* [**Proximal Policy Optimization**](https://arxiv.org/abs/1707.06347): This algorithm leverages a reward model that predicts whether a given text is highly ranked by humans. This prediction is then used to optimize the SFT model with a penalty based on KL divergence.
-* **[Direct Preference Optimization](https://arxiv.org/abs/2305.18290)**: DPO is another RL algorithm that does not need a reward model, making the RLHF process simpler and more lightweight.
+* **[Direct Preference Optimization](https://arxiv.org/abs/2305.18290)**: DPO simplifies the process by reframing it as a classification problem. It uses a reference model instead of a reward model (no training needed) and only requires one hyperparameter, making it more stable and efficient.
