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.

The two plots differ only in the area in the middle where the classes are tied. If break_ties=False , all input in that area would be classified as one class, ...

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.

apparently, it's a conflict between older & newer versions of SVC in sklearn. In the warning it tells i should probably use sklearn version = 0.19.1. I tried installing the current and upgrading to older sklearn. I can't use shell, it's restricted, so i run all code in jupyter:

I was a bit surprised to find that SVC doesn't do tie-breaking for OVO, as you can see here: import numpy as np import matplotlib.pyplot as ...

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.
