Webb30 nov. 2024 · First, we try using the scikit-learn Cost Complexity pruning for fitting the optimum decision tree. This is done by using the scikit-learn Cost Complexity by finding the alpha to be used to fit the final Decision tree. Pruning a Decision tree is all about finding the correct value of alpha which controls how much pruning must be done. Webb4 jan. 2024 · In scikit learn hyperparameter includes the number of decision trees and number of features considered by splitting each tree while the nodes are splitting. Code: In the following code, we will import RandomForestRegressor from sklearn.ensemble by which we can see the current use hyperparameter.

Webb28 feb. 2024 · AdaBoost works by putting more weight on difficult to classify instances and less on those already handled well. AdaBoost algorithms can be used for both classification and regression problems. AdaBoost is one of the first boosting algorithms to be adapted in solving practices.
