Uncertainty-Aware Credit Card Fraud Detection Using a Fuzzy Graph Attention Network with Weak-Signal Edge Preservation

Coordinated card fraud can leave only weak, partial traces between transactions, which crisp graph detectors discard. This study evaluates a Fuzzy Graph Attention Network (Fuzzy-GAT) in which Gaussian edge-membership weights modulate attention, so that weak-signal edges are preserved rather than pruned. Because the pub...
