Web21 ott 2014 · svm = LinearSVC () clf = CalibratedClassifierCV (svm) clf.fit (X_train, y_train) y_proba = clf.predict_proba (X_test) User guide has a nice section on that. By default CalibratedClassifierCV+LinearSVC will get you Platt scaling, but it also provides other options (isotonic regression method), and it is not limited to SVM classifiers. Share WebNuSVC的参数与KernelSVC类似,只不过KernelSVC的C参数被nu代替。 多分类与调参 这里设计的分类模型都继承了sklearn.base.BaseEstimator,意味着它们可以和sklearn中的一些功能匹配,比如多分类和调参:
