Embodiment 3

[0061] As a specific implementation of calculating the clustering index in the second embodiment of the present application, in order to reduce the workload of clustering processing, such as image 3 As shown, in the third embodiment of the present application, all face feature data are face feature vectors, and the selected clustering index type is the vector distance between the face feature vectors. The third embodiment of the present application includes:

[0062] S301. Perform feature vector fusion on all the second face feature data included in each feature data class, to obtain a second face feature vector corresponding to each feature data class.

[0063] Wherein, the specific eigenvector fusion method is not limited here, and can be set by technicians according to actual needs, including but not limited to, such as directly averaging the corresponding values ​​in each face eigenvector to obtain the corresponding second face Feature vector.

[0064] S302. Calculate ve...

Abstract

The invention provides a user identifier generation method and device, and a terminal device. The method and the device are suitable for the technical field of data processing. The method comprises the steps of performing feature analysis on an image containing a user face in first metadata to obtain first face feature data; matching the first face feature data with at least one piece of second face feature data, and screening out successfully matched third face feature data; obtaining second metadata corresponding to the third face feature data, and constructing a user portrait based on the first metadata and the obtained second metadata; and fusing the first face feature data and the third face feature data, and setting the fused face feature data and the fused third face feature data asuser identifiers of user portraits. The user identifier provided by the embodiment of the invention can cope with more scenes in different environments, has extremely strong coverage capability for matching scenes of real users and user portraits, and the method is more accurate and reliable in matching.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a user identification generation method and a terminal device. Background technique [0002] User portrait, that is, labeling of user information. After collecting and analyzing metadata such as user static attribute data, social attribute data, and behavior attribute data, a label system representing user attribute information is constructed to support big data scenarios such as personalized recommendation. The basic method of application, among which, the offline user portrait and the online user portrait refer to the two types of user portraits constructed after analyzing the user metadata collected offline and online respectively. [0003] When combining user portraits with actual scenarios, it is necessary to select or generate at least one user ID for user portraits to match user portraits with real users. Whether the user's ID number is the s...
