Scikit-learn provides three classes namely SVC, NuSVC and LinearSVC which can perform multiclass-class classification. SVC. It is C-support vector classification whose implementation is based on libsvm. The module used by scikit-learn is sklearn.svm.SVC. This class handles the multiclass support according to one-vs-one scheme. Parameters

As with any clustering solution, avoiding a split-brain situation (where nodes are no longer able to communicate with each other) requires a tie break.

break_ties bool, default=False. If true, decision_function_shape='ovr', and number of classes > 2, predict will break ties according to the confidence values of decision_function; otherwise the first class among the tied classes is returned. Please note that breaking ties comes at a relatively high computational cost compared to a simple predict.

SVM Tie Breaking Example¶. Tie breaking is costly if decision_function_shape='ovr', and therefore it is not enabled by default.This example illustrates the effect of the break_ties parameter for a multiclass classification problem and decision_function_shape='ovr'. The two plots differ only in the area in the middle where the classes are tied.
