SAGOD:Static Attributed Graph Outlier Detection中文README :cnREADME.md.SAGOD (StaticAttributedGraphOutlierDetection) is an implementation of anomaly detection models on static attributed graph. Inspierd byPyODandPyGOD, we designed convenient interface to train model and make prediction. SAGOD support the following models:AdONE: Adversarial Outlier Aware Network Embedding;ALARM: A deep multi-view framework for anomaly detection;ANOMALOUS: A Joint Modeling Approach for Anomaly Detection on Attributed Networks;AnomalyDAE: Anomaly Detection through a Dual Autoencoder;ComGA: Community-Aware Attributed Graph Anomaly Detection;DeepAE: Anomaly Detection with Deep Graph Autoencoders on Attributed Networks.DOMINANT: Deep Anomaly Detection on Attributed Networks;DONE: Deep Outlier Aware Network Embedding;GAAN: Generative Adversarial Attributed Network;OCGNN: One-Class GNN;ONE: Outlier Aware Network Embedding;Radar: Residual Analysis for Anomaly Detection in Attributed Networks.ResGCN: Residual Graph Convolutional Network.SADAG: Semi-supervised Anomaly Detection on Attributed Graphs.We are still updating and adding models. It's worth nothing that the original purpose of SAGOD is to implement anomaly detection models on graph, in order to help researchers who are interested in this area (including me).OverviewIntest.py, we generate anomaly data from MUTAG, and use different models to train it.

We improved it with vectorization, achieving a 100% performance improvement;We implemented ALARM, which can detect anomaly in multi-view graph;We implemented more models including ComGA, DeepAE, etc, which is not included in PyGOD;...Future PlanSupport batch mechanism and huge graph input;Support GPU;More models implementation;...ReferenceBandyopadhyay, Sambaran, Saley Vishal Vivek, and M.
