you just thought like me. Nothing wrong in it, because the random forest model also works the same as a forest in one perspective. Usually, an ensemble of trees are considered as forest, same like that, an ensemble of decision trees are considered as Random ...

Random Forest Random forest is an ensemble learning method to solve any classification and regression problem. Random forest training builds a model composition (ensemble) of one type and uses some aggregation algorithm of several answers from models. Each model is trained on a part of the ...

The Random Forest component is a classifier that consists of multiple decision trees. The classification result is determined by the mode of output classes of individual trees. Configure the component You can use one of the following methods to configure the Random Forest component. Method 1: ...

generally trained via the bagging method (or sometimes pasting),typically with max_samples set to the training set. instead of building a BaggingClassifier and passing it a DecisionTreeClassifier,you can instead use theRandomForestClassifier/ RandomForestRegressorclass,which is more convenient and ...
