Witryna14 cze 2024 · Flower classification is a very important, simple, and basic project for any machine learning student. Every machine learning student should be thorough with the iris flowers dataset. This classification can be done by many classification algorithms in machine learning but in our article, we used logistic regression. WitrynaHere is the Python code for extracting an individual tree (estimator) from Random Forest: ind_tree = (RF.estimators_[4]) print(ind_tree) DecisionTreeClassifier(max_features='auto', random_state=792013477) Here we are printing the 5th tree (index 4). We can create a dendrogram (or tree plot) similar to …
