How Important is the Reference Model in Direct Preference Optimization DPO? An Empirical Study on Optimal KL-Divergence Constraints and Necessity

Direct Preference Optimization (DPO) is an advanced training method to fine-tune large language models (LLMs). Unlike traditional supervised fine-tuning, which depends on a single gold reference, DPO ...

Reference model alignment with the current policy

I've been exploring the implementation of Proximal Policy Optimization (PPO) in the ppo_trainer.py file, and I have a query regarding the handling of the reference model (old policy) in relation to ...

On the Choice of an Appropriate Reference Model for Control of Multivariable Plants

Abstract: The choice of the reference model is the main task to be performed by the designer in a model reference control design. A poor choice of the reference model may result in a closed-loop ...
