Researchers have developed PACE (Proxy Alignment and Curvature Expansion), a new diagnostic tool designed to predict how human-perceived quality will change as optimization strength increases. Unlike previous methods that relied solely on average proxy-human correlation, PACE uses repeated human ratings to model the gain curve, approximating it with a formula that accounts for first-order alignment and second-order corrections. This method has demonstrated consistent improvements in predicting held-out gain errors across various datasets and experiments, including those involving GPT-4o and LoRA-DPO, and shows promise in bridging the gap to actual optimization.
