Embodiment Construction

[0064] The present invention will be further described in detail below in conjunction with specific embodiments, but the protection scope of the present invention is not limited to these embodiments, and all changes or equivalent substitutions that do not depart from the concept of the present invention are included within the protection scope of the present invention.

[0065] The multi-label classification method of social network users based on the dynamic multi-view learning model of the present invention comprises the following steps:

[0066] Step 1: Construct a user's multi-view representation matrix for a specific social network dataset:

[0067] Social network data generally includes user personal information and user-user relationship data, which constitutes a multi-view representation of users. Among them, user personal information is called a node attribute, and the relationship is called an edge between nodes; The first key task of multi-label classification is to...

Abstract

The invention provides a social network user multi-label classification method based on a dynamic multi-view learning model, and the method comprises the following steps: building multi-view representation of a user for a specific social network data set; based on the user representation, constructing a deep fusion representation model among the multi-view data; using a dynamic routing model, updating parameters, and optimizing multi-view characteristics; and introducing a shared representation model, and constructing an objective function for the features in the step 3; and through model optimization, obtaining an optimal shared representation matrix, and finally, realizing multi-label classification of any user by utilizing the shared matrix. According to the method, multi-label efficient classification of network users is realized. The problems of model learning performance reduction, limited view fusion quantity, incapability of meeting multi-classification task requirements of the model and the like caused by data loss are solved, and the method can be widely applied to scenes such as user accurate analysis, abnormal user detection, user relationship mining and unknown user identification in the network.

Description

technical field [0001] The invention discloses a multi-label classification method for social network users based on a dynamic multi-view learning model, and belongs to the field of information technology services. Background technique [0002] At present, the Internet has become an indispensable part of people's lives. Users generate a large amount of data such as text, images, and user relationships in different social networks (such as Weibo, Twitter, and WeChat), which are called multi-view data. These multi-view data imply a wealth of information, and the update speed is extremely fast. Therefore, the fusion of multi-view data has become a key technical issue in the field of data mining, and its research results can be applied to different fields. Network user analysis is an important application scenario. Users may have multiple category labels at the same time. In recent years, multi-label classification of the same user on different networks has attracted extensive a...
