WebThe output is consistent with the output of the predict_proba method of DecisionTreeClassifier / ExtraTreeClassifier / ExtraTreesClassifier / RandomForestClassifier / XGBRFClassifier / XGBClassifier / LGBMClassifier. Usage. Here's a simple example of how a linear model trained in Python environment can be represented in Java code: WebAccording to the documentation, a Ridge.Classifier has no predict_proba attribute. This must be because the object automatically picks a threshold during the fit process. Given the documentation, I believe there is no way to plot a ROC curve for this model. Fortunately, you can use sklearn.linear_model.LogisticRegression and set penalty='l2'.
