WebFeb 13, 2024 · Secondly, ExtraTreesClassifier (the first step in your pipeline), doesn't have a transform () method, either. You can verify that here, in the class docstring. Supervised learning models aren't made for transforming data; they're made for fitting on it and predicting based off that. What type of classes are able to do transformations? WebExtraTreesClassifier. An extra-trees classifier. This class implements a meta estimator that fits a number of randomized decision trees (a.k.a. extra-trees) on various sub-samples of the dataset and uses averaging to improve the predictive accuracy and control over-fitting.
