Graph Neural Networks for Real-Time Transaction Fraud Detection in Payment Networks
Modern payment fraud increasingly manifests through coordinated activity across cards, devices, merchants, customers, and IP addresses, making transaction-only models insufficient for detecting multi-entity attacks. This paper presents a real-time fraud detection framework based on a heterogeneous temporal graph neural...
