Abstract

The invention discloses a method, device and equipment for classifying users through a decision tree model, and relates to artificial intelligence, and the method comprises the steps of obtaining at least one user attribute of a to-be-classified user and a pre-created decision tree model; obtaining a Gini coefficient corresponding to each attribute node of the decision tree model in a current scene, wherein the Gini coefficient carries weight information of the attribute node corresponding to the current scene; starting from a root node of the decision tree model, sequentially determining expenditure nodes of attribute nodes of a next level according to the Gini coefficient; selecting user attributes existing in attribute nodes of the decision tree model from the user attributes to obtain matching attributes; and matching the obtained matching attribute with each node attribute in the decision-making tree model, and classifying the user according to the determined expenditure node of each level in the decision-making tree model.

Description

technical field [0001] The invention relates to the technical field of intelligent decision-making of artificial intelligence, in particular to a method, device, computer equipment and storage medium for classifying users through a decision tree model. Background technique [0002] The user LOOKALIKE model tool is an operating tool widely used in various companies and businesses. Its core principle is to discover users with a high similarity with the target user group in a specific scenario, and is often used in potential customers. Operations and promotion of new products / features. At present, the method system of LOOKALIKE is roughly divided into two types. One is the clustering method, which directly uses the indicators in the indicator library to find users who are closest to the target group under the Cartesian distance; the second is through supervised classification. Model, the target population is used as a positive sample, and the output model is then reversely use...
