Graph Anomaly Detection using GGAD Experiments Keywords:Generative method,Graph Anomaly Detection Abstract 这项工作考虑了一个实际的半监督图异常检测(GAD)场景,其中图中的部分节点已知是正常的,与广泛探索的无监督设置与完全无标记的图形成对比。我们发现,在适应半监督设置时,即使是只有一小部分正常节点,也可以访...

In this paper, we propose a Graph Edge Anomaly Detection model based on a Semi-supervised auto-encoder (GEADS). In this model, we first adjust the traditional mini-batch training strategy to train the model on a large-scale graph. It improves the scalability of the model. Second, we ...
Graph anomaly detection aims to identify the abnormal nodes in a graph that deviate from the majority of nodes, which is critical in fields such as finance and social network analysis. Due to the unbearable costs of labeling anomalies, existing methods are mainly tackled from unsupervised or sem...

Improving Unsupervised Anomaly Detection”, we propose a novel unsupervised AD framework that relies on the principles of self-supervised learning without labels and iterative data refinement based on the agreement ofone-class classifier(OCC) outputs. In “SPADE: Semi-supervised Anomaly Detection under ...

Intrusion Detection systems (IDS) are alerting cybersecurity tools that analyze network traffic in order to identify suspicious activity and known threats. State of the art IDS rely on supervised machine learning models which are trained to categorize the network flow with a historical labeled dataset...
