during the generation process, when constructing a decision tree in the row direction, bootstraping is used to obtain the training data, and no sampling is used to obtain the feature subset in the column direction. Then, the optimal splitting point is obtained, this is the basic principle of the random forest algorithm, such: In short, the random forest algorithm can avoid the over-fitting problem of decision trees, because random forest uses several decision trees to vote to determine the fin
