Systems and methods for multi-agent based fraud detection

A system for multi-agent based fraud detection, comprising:

• a generator module comprising:
• a plurality of generator agents;
• a generator configuration file comprising a plurality of transaction behaviors and a number or proportion of generator agents to act in accordance with each transaction behavior;
• and
• generated test data storage;
• a detector module comprising:
• a plurality of detector agents;
• a detector configuration file comprising a detector parameter for the detector agents to use;
• and
• a combiner that combines outputs of the plurality of detector agents;
• and
• a control module comprising a controller that controls the generator module and the detector module;
• wherein:
• the control module controls the generator agents to generate a first set of test data based on the transaction behavior, wherein the first set of generated test data comprises a first set of generated test transactions, and each generated test transactions comprises a fraud indicator based on the transaction behavior;
• the control module controls the detector agents using the first set of generated test data and the detector configuration file, wherein each detector agent outputs a first trained model object;
• and
• the control module controls the combiner to combine the first trained model objects and output a first trained detection model.
