Problems solved by technology

[0004] However, in actual situations, the user information of the same user on different application platforms may be the same, and the user credit determined by the above content may be unreasonable due to redundant user information.
In addition, the application platform may have the problem of partial lack of user information, and the above content also has certain unreasonable user credit due to the lack of user information

Embodiment Construction

[0061] In order to make the purpose, technical solution and advantages of this specification clearer, the technical solution of this specification will be clearly and completely described below in conjunction with specific embodiments of this specification and corresponding drawings. Apparently, the described embodiments are only some of the embodiments in this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this specification.

[0062] The Internet financial platform can determine the user's credit, and the user's credit can be represented by the user's credit score. When each application platform generates some business, each application platform can jump to the Internet financial platform, so that the Internet financial platform can process the business. For example, when the food delivery platform generates ser...

Abstract

The invention discloses a model training and business execution method and device, and the method comprises the steps: obtaining the user information of a user on each application platform, determining the user comprehensive features and first loss of the user through a to-be-trained first model corresponding to each application platform, and determining a target event and an annotation; inputtingthe user comprehensive features into to-be-trained second models corresponding to the target event to obtain an execution probability of executing the target event by the user, determining a second loss according to the execution probability and the label, and training each to-be-trained first model and each to-be-trained second model according to the first loss and the second loss. According tothe specification, the first model and the second model are obtained by training through the method, so the user comprehensive characteristics are obtained through each first model, the result obtained based on the user comprehensive characteristics and the second model is more reasonable, the problem of user information redundancy is solved, and the problem of user information loss is solved to acertain extent.

Description

technical field [0001] This specification relates to the field of Internet technology, and in particular to a method and device for model training and business execution. Background technique [0002] At present, the impact of Internet finance on daily life is gradually increasing. The Internet financial platform can determine the credit of the user, and recommend payment methods, Internet financial products, etc. to the user based on the credit of the user. [0003] Specifically, since users have user information on application platforms such as food delivery platforms, when users generate financial-related business on the application platform, the application platform jumps to the Internet financial platform to process related businesses. Therefore, the Internet financial platform According to the user information on each application platform, the user credit score of the user on each application platform can be determined separately, and the user credit score of each app...
