ROC Curve to ExampleSet

Synopsis​

This Operator takes a performance vector for which the AUC performance criterion was calculated and creates an ExampleSet with points of the ROC Curve.

Description​

The RocCurve2ExampleSet Operator takes a performance vector provided at the input port. The performance vector needs to contain the AUC criterion. The ROC Curve is then evaluated in the same way as in the Result view. The resulting ROC Curve Points (false positive rate, true positive rate (Mean), true positive rate (Standard Deviation), confidence threshold (Mean), confidence threshold (Standard deviation)) are delivered as an ExampleSet at the output port.

Input​

performance​

A performance vector. The performance vector needs to contain the AUC criterion.

Output​

example set​

ExampleSet containing the ROC Curve Points.

original​

The original performance vector.

Parameters​

Number of points​

Number of evaluation points.
