Abstract

The invention discloses a fraud probability analysis method and device, electronic equipment and a storage medium, and belongs to the technical field of electronic information.The fraud probability analysis method comprises the steps that user information data is acquired and cleaned, and a de-noised data set is obtained; inputting the de-noised data set into a trained machine learning model to obtain a community to which the user belongs; and calculating the probability that the user belongs to the fraudulent user according to the community to which the user belongs. The method is high in judgment speed, high in availability and capable of quickly and accurately judging whether the fraud risk exists or not.

Description

technical field [0001] The present application relates to the field of electronic information technology, and in particular to a fraud probability analysis method, device, electronic device and storage medium. Background technique [0002] The Internet finance and credit industry has developed rapidly in recent years. With the development of the industry, the fraudulent black industry chain is also constantly infiltrating this field. Various novel fraud models emerge one after another, which has cast a shadow on the healthy development of the online credit industry. A layer of shadow. According to statistics, the annual loss due to fraud is between 50 billion and 100 billion, and fraud risk prevention is extremely important. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide a fraud probability analysis method, apparatus, electronic device and storage medium, so as to at least solve the problem of existing financial c...
