ROC
Generates a Receiver Operating Characteristic (ROC), or ROC curve.
Information at a Glance
The ROC curve is used to verify and compare the trained model(s) passed from a preceding model operator or operators by applying the algorithm on the data set passed from a preceding operator. The ROC-AUC method considers the coordinate pairing of the false positive rate (FP) and the true positive rate (TP). This set of coordinates forms the Receiver Operating Characteristic (ROC) curve.
The value of the ROC curve can be summarized by calculating the Area Under the ROC curve (AUC).
A random model typically has an ROC curve running along the diagonal. A better model curves to the upper left-hand side, thus having an AUC value approaching one.
This operator can be applied, in general, to any classification model (for example, CART, Decision Tree, Logistic Regression, Naive Bayes, Neural Network and Alpine Forest Classification).
