Abstract: Ensemble learning now becomes much popular in the field of machine learning. "hhis paper introduced a new ensemble algorithm, SER-BagBoosting Trees ensemble algorithm, which was a combination of tree predictors and was based on variational similarity cluster technology and greedy method, and it was also combined with the features of Boosting and Bagging. Compared with a series of other learning algorithms, it often has better generalization ability and higher efficiency.

Key words: CART, Bootstrap, Selective ensemble
