Post pruning decision trees with cost complexity pruning
Webb2 okt. 2024 · We will use DecisionTreeClassifier from sklearn.tree for this purpose. By default, the Decision Tree function doesn’t perform any pruning and allows the tree to … WebbAn extra-trees regressor. 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.

Decision trees are an intuitive supervised machine learning algorithm that allows you to classify data with high degrees of accuracy. WebbIt is used when decision tree has very large or infinite depth and shows overfitting of the model. In Pre-pruning, we use parameters like ‘max_depth’ and ‘max_samples_split’. But here we prune the branches of decision tree using cost_complexity_pruning technique. ccp_alpha, the cost complexity parameter, parameterizes this pruning ... undertow danny gokey lyrics
