Semi-Supervised Mul-GAD Robustness to Adversarial Attacks on Heterophilic Graphs

This report synthesises findings from 15 peer-reviewed papers addressing the following research question: How does the semi-supervised approach in Mul-GAD affect its robustness to adversarial attacks compared to fully unsupervised GNN-based anomaly detection methods on heterophilic graphs, measured by. Graph anomaly detection (GAD) under semi-supervised setting poses a significant challenge due to the distinct structural distribution between anomalous and normal nodes. Specifically, anomalous nodes constitute a minority and exhibit high heterophily and low homophily compared. 9 claims were extracted from source literature; 9 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 8.0/10. This report is a machine-generated literature synthesis and does not constitute original research.

Research goal: How does the semi-supervised approach in Mul-GAD affect its robustness to adversarial attacks compared to fully unsupervised GNN-based anomaly detection methods on heterophilic graphs, measured by AUC scores?
