Abstract

Embodiments of the present invention provide a decision tree-based classification calculation method, computer equipment, and a computer-readable storage medium, which solve the problems of slow calculation speed, high computational complexity, and excessive cache required in the existing decision tree-based classification calculation method The problem. The classification calculation method based on the decision tree includes: inputting a plurality of samples to be classified into the root node of the decision tree; Parallelized classification calculation is performed on the samples of the current non-root node.

Description

technical field [0001] The present invention relates to the technical field of data analysis, in particular to a decision tree-based classification calculation method, device, computer equipment and computer-readable storage medium. Background technique [0002] Decision tree is an important classification calculation method in sample classification algorithm. A decision tree consists of a root node and multiple non-root nodes subordinate to the root node. Each node in the decision tree will judge a characteristic value of the sample, and judge the size of the judgment threshold of the node, and assign the sample to the judgment node of the next layer according to the result, and the characteristic value judged by the node of each layer of the same classification. If the node is a leaf node without child nodes, the classification ends, and the classified samples of each leaf node can be regarded as a classification calculation result. [0003] The traditional decision tre...
