Abstract

The present invention provides a user loss early warning processing method and device. The method includes: classifying the first service characteristic information of the lost user according to preset dimensions, and obtaining the first service characteristic information in each dimension; according to the preset user type, cluster the first service feature information corresponding to the same user type in the first service feature information under each dimension, and obtain the first service feature information of each dimension under different user types; according to the user to be tested The user churn prediction model corresponding to the user type predicts the second service characteristic information of the user to be tested, and obtains the churn risk coefficient of the user to be tested, and the user churn prediction model is based on different user types in each dimension The first service feature information is established by performing machine learning. Therefore, the accuracy rate of user loss risk prediction can be improved, thereby reducing user loss and reducing enterprise losses.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a user loss early warning processing method and device. Background technique [0002] With the development of Internet services, the types of telecommunication broadband available to users are gradually increasing. In the telecommunication industry, the cost of acquiring new users is far greater than the maintenance of old users. Therefore, in order to achieve user retention, it is necessary to Predict the probability of churn. [0003] The existing user churn prediction method generally obtains all the business data of the current user from various business systems, and directly establishes a user churn probability model based on the acquired business data of the current user, and realizes the calculation of the user churn probability. [0004] However, when using the above method to calculate the probability of user loss, some data with a small proportion are often ignored in th...
