Graph Contrastive Anomaly Detection Robustness Against Adversarial Perturbations on Amazon Co-Author Networks

Abstract

Abstract: This report synthesises findings from 4 peer-reviewed papers addressing the following research question: What is the robustness of graph contrastive anomaly detection models against adversarial perturbations compared to supervised methods when measured by detection accuracy on perturbed Amazon co-author. Machine learning models have made many decision support systems to be faster, more accurate and more efficient. However, applications of machine learning in network security face more disproportionate threat of active adversarial attacks compared to other domains. 12 claims were extracted from source literature; 12 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 8.3/10. This report is a machine-generated literature synthesis and does not constitute original research.
