Fraud detection & investigation

Fraud operations review transactions and accounts using detection systems that may produce alerts or scores, but explanations can be separate, post-hoc, and too costly or weak to support real-time operational judgment.

PAINBank fraud teams need fraud detection that is not only accurate, but explainable enough to use in real operations; prior graph-based fraud detection work often overlooked interpretability, and post-hoc explanations could be too costly for practical use.
