Abstract:
1. A computer-implemented method of generating a model for performing account-level fraud detection, comprising: obtaining a plurality of candidate rules for referrals of financial transactions; electronically determining with a processor one or more initial value densities that correspond to per account savings levels associated with applying the candidate rules to financial transactions; electronically selecting a rule from the plurality of candidate rules based on the determined value densities; iteratively rebalancing value densities for the remaining rules of the plurality of candidate rules and selecting a next rule with the processor until a volume constraint is satisfied, to obtain a sub-set of rules from the plurality of candidate rules for application to one or more financial transactions, wherein the rebalanced value density for at least one of the remaining rules is different than the initial value density for the at least one of the remaining rules; and providing the sub-set of rules for use by a fraud detection system in referring financial transactions for fraud-related action.
