ROC curve
ROC curve: A curve showing true-positive rate and false-positive rate as the classification threshold varies. ROC-AUC summarises ranking but can look optimistic with rare classes. Precision-recall curves expose false positives better in that setting. This perspective connects the definition with practical behaviour in artificial intelligence systems.
