WebbThe receiver operating curve metric is used for evaluating the anomaly detection algorithms. The area under this curve is also computed. The large the value of AUC, the more accurate will be the performance of the algorithm. Receiver operating curve is plotted using true positive and false positive values of algorithm. WebbThe ROC curve is a fundamental tool for diagnostic test evaluation. Theory summary The diagnostic performance of a test, or the accuracy of a test to discriminate diseased cases from normal cases is evaluated using Receiver Operating Characteristic (ROC) curve analysis (Metz, 1978; Zweig & Campbell, 1993).
