GADBench: Revisiting and Benchmarking Supervised Graph Anomaly Detection

1 code implementation NeurIPS 2023 Jianheng Tang, Fengrui Hua, Ziqi Gao, Peilin Zhao, Jia Li

With a long history of traditional Graph Anomaly Detection (GAD) algorithms and recently popular Graph Neural Networks (GNNs), it is still not clear (1) how they perform under a standard comprehensive setting, (2) whether GNNs can outperform traditional algorithms such as tree ensembles, and (3) how about their efficiency on large-scale graphs.
