Abstract

The invention provides a method, a system and a terminal for predicting age characteristics based on a decision tree model. The method comprises the following steps: collecting basic data information; extracting a characteristic input variable and a target variable in the attribute of the basic data information to get sample data; dividing the sample data into a training set and a test set, inputting the training set to a decision tree model for model parameter training, and applying the model parameter training result to the test set to test the model parameter training result meeting a custom stability condition; outputting the model parameter training result meeting the custom stability condition; and regularly updating the rule of the output model parameter training result to the age prediction result of an unknown user. According to the method, the system and the terminal for predicting age characteristics based on a decision tree model provided by the invention, a prediction model is built to predict the ages of users, the portraits of users are constructed precisely, a solid data foundation is laid for marketing and other scenes, and the accuracy of age identification is improved.

Description

technical field [0001] The present invention relates to the field of e-commerce, in particular to a method, system and terminal for predicting age characteristics based on a decision tree model. Background technique [0002] In user-based industries such as e-commerce or social networking, it is often necessary to know the real age of users in order to classify them and facilitate the study of their behavioral characteristics and preferences. However, the Internet is a virtual world, and users have a kind of vigilance when they swim freely, so as to hide part of their true identities. [0003] However, groups of different ages have distinctive behavioral characteristics, and their real age can be displayed through their own behavioral characteristics. Targeted processing and feature extraction of behavioral characteristic data can greatly improve the accuracy of age prediction. [0004] In the prior art, a regression model is used for age prediction. In the process of rese...
