ACI Worldwide announced that the patent for its incremental learning technology an innovative industry-first approach to machine learning has received full approval. Incremental learning technology is an integral part of ACI Fraud Management and considerably enhances fraud protection for merchants and financial institutions. While traditional machine learning models need to be ‘re-trained’ as fraud patterns change, models using incremental learning make small adjustments on an ongoing basis, allowing the model to adapt itself in production when new behaviors are observed.
