Classification: CPC H  G | IPC G  H

Claim 14:
15. A method comprising:
determining, by an authentication system, a plurality of rules that were previously used to evaluate a plurality of financial transactions;
generating, by the authentication system, a cleaning coefficient for a set of one or more rules of the plurality of rules, wherein the cleaning coefficient indicates how the set of one or more rules of the plurality of rules is performing, where the cleaning coefficient is based at least in part on whether the set of one or more rules prevents one or more financial transactions of the plurality of financial transactions;
identifying, by the authentication system, the set of one or more rules from the plurality of rules to eliminate from the plurality of rules, based at least in part on the cleaning coefficient, wherein a machine learning module is used to identify the set of one or more rules or is trained using the set of one or more rules;
eliminating, by the authentication system, at least one rule of the set of one or more rules from the plurality of rules to generate a modified set of rules, based on the identified set of one or more rules to eliminate;
authenticating or preventing, by the authentication system, a transaction based on the modified set of rules;
identifying a set of one or more attributes associated with the identified set of one or more rules to eliminate: and
training the machine learning module based at least in part on the identified set of one or more attributes associated with the identified set of one or more rules to eliminate.
