Claim 8:
9. A system comprising:
at least one processor programmed or configured to:
receive transaction data associated with a plurality of transactions, the plurality of transactions including a plurality of non-fraudulent transactions and a plurality of fraudulent transactions;
generate at least one decision tree having a root node and at least one child node operably connected to the root node based on the transaction data associated with the plurality of transactions;
determine at least one primary rule and at least one set of secondary rules associated with the at least one primary rule based on the plurality of non-fraudulent transactions and the plurality of fraudulent transactions;
populate the at least one decision tree based on the at least one primary rule and the at least one set of secondary rules;
extract a plurality of rule sets from the at least one decision tree;
determine an ordering of the plurality of rule sets based on memory-based efficiency characteristics and fraud-detection-based characteristics associated with each rule set of the plurality of rule sets; and
determine whether the ordering of the plurality of rule sets satisfy a minimum efficiency threshold.
