I can reproduce your problem with the following code: for model, classifier in zip (models,classifiers.keys ()): print (classifier [classifier]) AttributeError: 'RandomForestClassifier' object has no attribute 'estimators_'. So, you need to rethink your loop. rf_feature_imp = RandomForestClassifier(100) feat_selection = SelectFromModel(rf_feature_imp, threshold=0.5) Then you need a second phase where you use the reduced feature set to train a classifier on the reduced feature set. Let's work through a quick example. param = [10,15,20,25,30, 40] `AttributeError: 'GridSearchCV' object has no attribute 'best_estimator_' لمعلوماتك ، فإن max_features "auto" و "sqrt" هي نفسها. # Author: Kian Ho <hui.kian.ho@gmail.com> # Gilles Louppe <g.louppe@gmail.com> # Andreas Mueller <amueller@ais.uni-bonn.de> # # License: BSD 3 Clause import matplotlib.pyplot as plt from collections import OrderedDict from sklearn.datasets import make_classification from sklearn.ensemble import RandomForestClassifier RANDOM_STATE = 123 .

Parameters ----- estimators : list of (string, estimator) tuples Invoking the ``fit`` method on the ``VotingClassifier`` will fit clones of those original estimators that will be stored in the class attribute `self.estimators_`. 최소의 분류 모델로 GridsearchCV를 실행하여 최적화하려고합니다. A random forest is a meta estimator that fits a number of classifical decision trees on various sub-samples of the dataset and use averaging to improve the predictive accuracy and control over-fitting. sklearn.grid_search import GridSearchCV from sklearn.datasets import make_classification from sklearn.ensemble import RandomForestClassifier # Build a classification task using 3 informative features X, y = make_classification(n_samples=1000, n_features=10, n . `AttributeError: 'GridSearchCV' object has no attribute 'best_estimator_' 25. cross-validation python random-forest scikit-learn. Note: Estimators implement predict method (Template reference Estimator, Template reference Classifier) The StackingCVClassifier extends the standard stacking algorithm (implemented as StackingClassifier) using cross-validation to prepare the input data for the level-2 classifier. It's a pretty simple solution, and relies on a custom accuracy metric (called weightedAccuracy) since I'm classifying a highly unbalanced dataset. Just put these statements before you call RFECV and then redefine the estimator i.e., AdaBoostRegressorWithCoef(n_estimators = 200.etc.) Otherwise, the importance_getter parameter should be used.. threshold str or float, default=None sklearn.grid_search import GridSearchCV from sklearn.datasets import make_classification from sklearn.ensemble import RandomForestClassifier # Build a classification task using 3 . Sempre que faço isso, recebo um AttributeError: "RandomForestClassifier" object has no attribute "best_estimator_", e não pode dizer por que, como parece ser um atributo legítimo na documentação.
