Abstract
This application discloses a method to train a decision tree model. The method is performed by a training system. The training system includes N processing subnodes and a main processing node, N being a positive integer greater than 1. The method includes separately obtaining, by each processing subnode for a currently being trained tree node, a node training feature set and gradient data of the currently being trained tree node; separately determining, by each of the processing subnode, a local splitting rule for the currently being trained tree node according to the node training feature set and the gradient data that are obtained, and transmitting the local splitting rule to the main processing node; and selecting, by the main processing node, a splitting rule corresponding to the currently being trained tree node from the local splitting rule determined by each of the processing subnode.
