Risk information determination method, model training method, equipment and program product

Abstract

The invention provides a risk information determination method, a model training method, equipment and a program product. The method comprises the steps of obtaining to-be-evaluated business data of a business activity; the to-be-evaluated business data comprise a plurality of data features, and each data feature corresponds to a feature domain; inputting the data features corresponding to the same feature domain into a coding network corresponding to the feature domain to obtain feature vectors corresponding to the feature domain; inputting feature vectors corresponding to the feature domain into an attention layer to obtain a total vector including a relationship between the feature vectors; inputting the total vector into a determination sub-module, and determining an expectation corresponding to the to-be-evaluated business data by using the determination sub-module; and determining risk information corresponding to the to-be-evaluated business data according to the expectation. According to the method provided by the invention, the data features belonging to the feature domain are processed through the coding network corresponding to the feature domain to obtain the feature vector of the feature domain, so that the feature vector of the service activity is accurately extracted, and the risk assessment result can be accurately obtained.

Description

technical field [0001] The present disclosure relates to artificial intelligence technology, and in particular to a risk information determination method, model training method, equipment, and program product. Background technique [0002] At present, online shopping platforms have become more and more mature, and each online shopping platform will also launch a variety of preferential activities to promote the transaction volume of commodities. With the increase of preferential activities, the black and gray industry based on online shopping platforms has been born. Some users reserve a large number of online shopping platform accounts, and use these accounts to participate in preferential activities and carry out arbitrage. [0003] In order to deal with the black and gray industry of the online shopping platform, the risk assessment technology exists in the existing technology, and it is an effective means to prevent the black and gray industry by conducting risk assessm...
