  • DETERMINING FRAUD RISK INDICATORS USING DIFFERENT FRAUD RISK MODELS FOR DIFFERENT DATA PHASES
    Publication number: 20210097543
    Abstract: Different fraud risk models can be developed and applied for a consortium of e-commerce merchants. With this multi-phase modeling strategy, a consortium member can get its optimal model performance at different data phases from an early phase where the consortium member does not have any historical data, to a more mature phase where the consortium member has a short time period of matured data, to a fully mature phase where the consortium member has a long-time period of matured data. On the other hand, the matured consortium data is not affected by the immature data from new members. Thus, the model performance for long-time existing members is not affected by new members at immature phases.
