Webb30 nov. 2024 · OutputCodeClassifier() with the default settings fits 1.5x number of classes binary classifiers, assigns Hamming codes to classes, then selects the nearest class when doing prediction. As you can see, interpreting this in a probabilistic way is not so trivial! Thus, predict_proba() method is not provided. You can still try a sort of a hacky …

Webbsklearn.multiclass.OutputCodeClassifier¶ class sklearn.multiclass.OutputCodeClassifier(estimator, code_size=1.5, random_state=None, n_jobs=1)¶ (Error-Correcting) Output-Code multiclass strategy. Output-code based strategies consist in representing each class with a binary code (an array of 0s and 1s). WebbOutput-code based strategies consist in representing each class with a binary code (an array of 0s and 1s). At fitting time, one binary classifier per bit in the code book is fitted. At prediction time, the classifiers are used to project new points in the class space and the class closest to the points is chosen.
