An Overview and Brief Explanation of Direct Preference Optimization (DPO)
DEV Community dev.to
Direct Preference Optimization (DPO) is fundamentally a streamlined approach for fine-tuning substantial language models such as Mixtral 8x7b, Llama2, and even GPT4. It’s useful because it cuts down on the complexity and resources needed compared to traditional methods. It makes the process of training language models more direct and efficient by using preference data to guide the model’s learning, bypassing the need for creating a separate reward model.
Imagine you’re teaching someone how to cook a complex dish. The traditional …
