Abstract

The invention relates to the field of user portraits, and discloses a user portrait establishment method and device based on clustering, a medium and electronic equipment. The method comprises the steps of acquiring multiple pieces of sample behavior data, each piece of sample behavior data corresponding to one user, wherein the sample behavior data comprise multiple attribute values; pre-clustering the users corresponding to the sample behavior data to divide the plurality of users into a plurality of initial classes; according to the attribute value of each piece of sample behavior data andthe initial class to which the user corresponding to each piece of sample behavior data belongs, carrying out secondary clustering on the user corresponding to each piece of sample behavior data so asto divide the plurality of users into a plurality of classes; determining a user portrait corresponding to each type according to the attribute value in the sample behavior data corresponding to theuser in each type; and determining the user portrait of the user corresponding to the target behavior data based on the user portraits corresponding to the types. According to the method, the accuracyof the established user portrait is improved, and the possibility of phenomena of over-fitting, poor generalization ability and the like is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of user portraits, and in particular to a method, device, medium and electronic equipment for establishing a user portrait based on clustering. Background technique [0002] With the advent of the Internet, especially the mobile Internet era, the amount of data generated by Internet users has grown rapidly. In order to gain insight into the online behavior characteristics of users, thereby providing guarantees for refined operations and enabling business growth, big data analysis is used to establish User portraits have become a popular research direction for people in related fields. However, with the increase of user data, the data dimensions used to build user portraits also increase, which leads to the current user portraits prone to overfitting, poor generalization ability, and inaccurate and detailed description of user behavior characteristics. And other issues. Contents of the invention ...
