Abstract

The invention provides a user state single-classification model training method and device. The method includes the steps that at least two positive training samples belonging to the assigned user state class are obtained; each positive training sample comprises at least two items of user attribute information; the sample feature vector of each positive training sample is extracted according to all the user attribute information of each positive training sample; model parameters are estimated according to the sample feature vectors, and a probability density function model is generated according to the estimated model parameters; a user state single-classification model is generated, the user state single-classification model comprises the probability density function model for receiving the input feature vectors and working out function values and further comprises a classification judging model for working out classification results for representing whether the samples belong to the assigned user state class or not according to the obtained function values. The user state single-classification model training method and device are good in classification performance, small in influence of human factors and high in generalization ability.

Description

technical field [0001] The invention relates to the technical field of computer information processing, in particular to a user state single classification model training method and device. Background technique [0002] User status is a description of user attributes in stages. For example, user status can be student status, parenting status, single status, and so on. By detecting user status, differentiated services can be provided according to user status, such as pushing information or providing services only to users with specific user status, or pushing different information or providing different services to users with and without specific user status. Serve. [0003] At present, there is a relatively simple method for detecting the user status, which requires the user to set his own user status and store it, so that the user status set by the user can be read when necessary to achieve the purpose of detecting the user status. However, this method for detecting the u...
