plotroc

Plot receiver operating characteristic

Syntax

plotroc(targets,outputs)

plotroc(targets1,outputs2,'name1',...)

Description

plotroc(targets,outputs)plots the receiver operating characteristic for each output class. The more each curve hugs the left and top edges of the plot, the better the classification.

plotroc(targets1,outputs2,'name1',...)generates multiple plots.

Plot Receiver Operating Characteristic

Open Live Script

This example shows how to plot the receiver operating characteristic for each output class in a pattern network.

loadsimplecluster_datasetnet = patternnet(20); net = train(net,simpleclusterInputs,simpleclusterTargets); simpleclusterOutputs = sim(net,simpleclusterInputs); plotroc(simpleclusterTargets,simpleclusterOutputs)

Figure Receiver Operating Characteristic (plotroc) contains an axes object. The axes object with title ROC contains 8 objects of type line. These objects represent Class 1, Class 2, Class 3, Class 4.
