5. Differences between kfold, structured kfold, structured shufflesplit and groupkfold and implementation of structured group kfold In machine learning, we can't take the whole data set directly for training, but use the cross validation method for training. Enhance randomness and reduce noise to reduce over fitting, so as to obtain and le ...

Decision tree algorithm type Decision tree is a series of algorithms, not an algorithm. The decision tree includes ID3 classification algorithm, C4.5 Classification Algorithm, Cart classification tree algorithm and Cart regression tree algorithm. Decision tree can be used as both classification algorithm and regression algorithm. Therefore, de ...
