New metric gSAP enhances representation learning by considering all query pairs

Researchers have introduced Global Average Precision for Representation Learning (gSAP), a novel differentiable surrogate metric designed to improve the training of machine learning models. Unlike traditional metrics that evaluate queries individually, gSAP considers all query-candidate pairs within a batch simultaneously. This holistic approach allows for more consistent similarity comparisons across queries, even when using a single decision threshold. The metric has demonstrated improvements in supervised metric learning, cross-modal alignment, and self-supervised pretraining, outperforming established methods like InfoNCE and other AP surrogates in various benchmarks.
