Web8 apr. 2016 · I am using Sklearn to train an SVM. My classes are unbalanced. Note that my problem is multiclass, multilabel so I am using OneVsRestClassifier: mlb = MultiLabelBinarizer () y = mlb.fit_transform (y_train) clf = OneVsRestClassifier (svm.SVC (kernel='rbf')) clf = clf.fit (x, y) pred = clf.predict (x_test) Web16 apr. 2024 · 2 There are multiple things to consider here: 1) You see, OneVsRestClassifier will separate out all labels and train multiple svm objects (one for each label) on the given data. So each time, only binary data will be supplied to single svm object.
