Precision-recall AUC
Precision-recall AUC: A summary of the precision-recall relationship across thresholds, particularly informative with a rare positive class. It depends on prevalence and interpolation method. It does not replace threshold selection, error costs and calibration analysis. This perspective connects the definition with practical behaviour in artificial intelligence systems.
