Question

A plot of false alarms versus hits for any given sensitivity is known as a ROC (receiver operating characteristic) curve. This curve is commonly used in signal detection theory to evaluate the performance of a binary classification system. The curve shows the tradeoff between true positive rate (hits) and false positive rate (false alarms) for different thresholds or sensitivities. A higher area under the ROC curve indicates better performance.
