sklearn.multiclass.predict_ovr(*args, **kwargs)[source]

DEPRECATED: predict_ovr is deprecated and will be removed in 0.18.Use the OneVsRestClassifier instead.

Predict multi-class targets using the one vs rest strategy.


estimators : list of n_classes estimators, Estimators used for

predictions. The list must be homogeneous with respect to the type of estimators. fit_ovr supplies this list as part of its output.

label_binarizer : LabelBinarizer object, Object used to transform

multiclass labels to binary labels and vice-versa. fit_ovr supplies this object as part of its output.

X : (sparse) array-like, shape = [n_samples, n_features]



y : (sparse) array-like, shape = [n_samples] or [n_samples, n_classes].

Predicted multi-class targets.
