Here, we are using some of its modules like train_test_split, DecisionTreeClassifier and accuracy_score. It is a numeric python module which provides fast maths functions for calculations. WebBoth probability estimates and non-thresholded decision values can be provided. The probability estimates correspond to the probability of the class with the greater label, i.e. estimator.classes_[1] and thus estimator.predict_proba(X, y)[:, 1]. The decision values corresponds to the output of estimator.decision_function(X, y).
