Graph anomaly detection is crucial for identifying unusual patterns in graph-based data with applications in web security and financial fraud detection.
Existing methods in graph anomaly detection rely on contrastive learning, which may be compromised by disruptive noise introduced by interfering edges.
To address this limitation, a Clean-View Enhanced Graph Anomaly Detection framework (CVGAD) is proposed, incorporating a multi-scale anomaly awareness module and a progressive purification module.
Experiments conducted on five benchmark datasets demonstrate the effectiveness of the CVGAD framework in improving anomaly detection performance.
