Classifier for multiclass

20.2.2 Multiclass SVM. Classical approaches construct the multiclass classifier as the combination of N independent binary classification tasks. Binary tasks are defined in the output code matrix R of size M N, where M is the number of classes, N is the number of tasks, and Rij ∈ {−1, 0, 1}
