AUTOMATIC FRAUD DETECTION

Abstract:

Embodiments provide a computer implemented method, including: ingesting, by the processor, a data file including financial transaction data; generating, by the processor, a schema from the financial transaction data; identifying, by the processor, a data type of each data field in the schema; performing, by the processor, feature selection to select a plurality of data fields from the schema; performing, by the processor, data sampling to select candidate rows of the schema based on the selected data fields; clustering, by the processor, the sampled data to different categories; selecting, by the processor, a set of analytical models for risk prediction, wherein each analytical model corresponds to a data type of each selected data field, and each analytical model generates a risk score; and generating, by the processor, a single risk score indicating the fraud risk by combining all the risk scores generated by the set of analytical models.
