Problems solved by technology

[0003] At present, in the identification technology of credit card user risk category, all user information related to the user is generally used for modeling, but all user information is not differentiated and screened, making it difficult to effectively extract user information that has a significant impact on credit card risk. As a result, the identification accuracy of credit card user risk categories in this way is not high enough

Abstract

The invention relates to a credit card user risk category identification method and device, computer equipment, a storage medium and a computer program product, and is applied to the field of big data. According to the invention, the identification accuracy of the credit card user risk category can be improved. The method comprises the following steps: acquiring user information of a credit card user; utilizing a stepwise regression model and a multivariate logistic regression model to screen out a plurality of risk influence factors from the user information; and inputting the attribute values corresponding to the plurality of risk influence factors into a pre-constructed decision tree model for traversal, and obtaining a risk category which the credit card user belongs to and is output by the decision tree model.

Description

technical field [0001] The present application relates to the field of big data technology, in particular to a credit card user risk category identification method, device, computer equipment, storage medium and computer program product. Background technique [0002] With the popularity of credit cards, credit card business is playing an increasingly important role in the banking system. Predicting whether a credit card user is a risk user is conducive to identifying risk users and high-quality users as early as possible, so that the bank can take timely measures to reduce the credit card limit of risk users and moderately increase the credit card limit of high-quality users, so as to reduce the losses caused by risk users and hope for better To provide services to high-quality users. [0003] At present, in the identification technology of credit card user risk category, all user information related to the user is generally used for modeling, but all user information is no...
