Claim 18:
19. Non-transitory computer-readable storage media having computer-executable instructions for real-time transaction fraud vetting, wherein when executed by at least one processor the computer-readable instructions cause the at least one processor to:
receive a transaction record that includes real-time transaction data relating to a transaction of an accountholder;
match the transaction record to an applied fraud model that includes—
a plurality of long-term profiles of the accountholder that correspond respectively to a plurality of attributes of transaction behavior of the accountholder, each of the plurality of long-term profiles defining one or more normal values for each of the plurality of attributes computed from historical transaction records of the accountholder, and
an artificial intelligence classifier that is constructed according to at least one of: a neural network, case-based reasoning, a decision tree, a genetic algorithm, fuzzy logic, and rules and constraints, the artificial intelligence classifier being trained to flag fraudulent activity based on historical transaction data of a plurality of accountholders;

increment a transaction risk for each instance in which the transaction record reflects a real-time deviation from the one or more normal values of one of the plurality of long-term profiles that exceeds a corresponding threshold;
input the real-time transaction data to the artificial intelligence classifier to generate an exception, the real-time transaction data being input to the artificial intelligence classifier in real-time and in parallel with the incrementing of the transaction risk;
output a fraud likelihood determination from the applied fraud model in real-time based at least in part on the incremented transaction risk and the exception; and
update the plurality of long-term profiles based on the transaction record to generate an updated plurality of long-term profiles for the accountholder.
