Abstract

The invention provides an evaluation model updating method and an evaluation model updating system. The evaluation model updating method according to the invention comprises the steps of monitoring stability and/or accuracy of a current evaluation model which is operated in an operation platform; if the current evaluation model is instable or inaccurate, generating a new evaluation model, and operating the new evaluation model in a testing platform for determining whether the new evaluation model is useful until a useful new evaluation model is generated; and replacing the current evaluation module which is operated in the operation platform by the useful new evaluation model. The evaluation model updating method and the evaluation model updating system according to the invention have advantages of realizing real-time updating of the evaluation algorithm, shortening period, improving system performance and reducing cost.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to an evaluation model updating method and system. Background technique [0002] Evaluation models (scoring models) are widely used. For example, applications such as borrowing and lending need to evaluate the user's credit, and the credit scoring model will be used; another example, applications such as advertising and analyzing user purchase needs need to evaluate the user's needs, and the demand scoring model will be used. [0003] The current technical solution is usually to complete the sample training offline, establish an evaluation model, and then manually verify the evaluation model offline, and then go online after the verification is passed. [0004] Taking the loan process as an example, the generation and update process of the evaluation model for evaluating user credit is as follows: [0005] Use existing samples for training and build an evaluation model; ...
