Abstract

The invention provides a family member attribute prediction method based on a subject model, a device and an intelligent terminal. The method includes: obtaining a probability distribution of each video in the media asset library on each topic; according to the user's preference weights for each video and the probability distribution of each video on each topic, the user's topic preference probability distribution is generated. Using the probability distribution of user's topic preference as the input feature of the logistic regression model, the probability distribution of various user's attributes output from the logistic regression model is obtained. According to the probability distribution of various user attributes, the number of attributes conforming to the salient attribute characteristics is counted, the number of attributes conforming to the salient attribute characteristics is confirmed as the number of family members, and the user attributes corresponding to each family member are recorded. The family member attribute prediction method provided by the present application can greatly improve the family member attribute characteristic coverage, and effectively enrich thebasic attribute dimension of a large screen user portrait crowd.

Description

technical field [0001] The present disclosure relates to the technical field of computer data mining, and in particular to a family member attribute prediction method, device and intelligent terminal based on a topic model. Background technique [0002] At present, in order to improve product services and increase corporate profits, major video websites have implemented more and more user portraits in various business fields where products and users interact A big data optimization strategy based on the comprehensive analysis results of dimension information data). For example, in order to improve user experience, increase user stickiness, organize and recommend videos to users in a personalized way, or carry out personalized advertising in order to improve the accuracy of advertising delivery and increase the input-output ratio. [0003] Different from mobile devices, large-screen devices are family shared devices. For most devices, there are more than one user roles, and ...
