Plot receiver operating characteristic

Syntax

• plotroc(targets,outputs)
  plotroc(targets1,outputs1,'name1',targets,outputs2,'name2', ...)
  

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.

Example

• load simplecluster_dataset
  net = newpr(simpleclusterInputs,simpleclusterTargets,20);
  net = train(net,simpleclusterInputs,simpleclusterTargets);
  simpleclusterOutputs = sim(net,simpleclusterInputs);
  plotroc(simpleclusterTargets,simpleclusterOutputs);
