Overview
An evaluation principle for monitoring DPO training progress by computing loss and preference accuracy on held-out data.
Description
DPO Validation evaluates the trained policy on a held-out preference dataset without gradient computation. It measures the DPO loss and preference accuracy (fraction of times the model assigns higher probability to the chosen response) to detect overfitting and monitor alignment progress.
Usage
Use at configured evaluation intervals during DPO training.
Theoretical Basis
Preference accuracy measures alignment quality:
