Embodiment Construction
[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0035] It should be noted that the vast majority of data mining methods are machine learning or deep learning methods. Among many algorithms, xgboost (Extreme Gradient Boosting) is a large-scale parallel algorithm, which is in the GradientBoosting Decision Tree (GBRT) developed on the basis. Studies have shown that compared with traditional GBRT, xgboost can parallelize multi-core CPUs for calculations, and under the same conditions, it can improve by more than 10 ti...
