Higher dimensional surfaces are used to examine the diagnostic performance of multiclass classification systems. These surfaces are extensions of the ROC curve and are known as ROC surfaces or manifolds. Manifolds may be constructed from either the correct classifications or from the misclassifications ...
ROC Curve for Multiclass Classification For a multiclass classifier, therocmetricsfunction computes the performance metrics of a one-versus-all ROC curve for each class, and theaveragefunction computes the metrics for an average of the ROC curves. You can use theplotfunction to plot a ROC curve...
