For l classes C1, ..., Cl, given a vector X= (x1, …, xn) of class labels computed at the prediction stage of the classification algorithm and a vector Y= (y1, …, yn) of expected class labels, the problem is to evaluate the classifier by computing the confusion matrix and connected quality metrics: precision, error rate, and so on.
QualityMetricsId for multi-class classification is confusionMatrix.
