MetaGAD: Learning to Meta Transfer for Few-shot Graph Anomaly Detection. (arXiv:2305.10668v1 [cs.LG])
cs.CR updates on arXiv.org arxiv.org
Graph anomaly detection has long been an important problem in various domains
pertaining to information security such as financial fraud, social spam,
network intrusion, etc. The majority of existing methods are performed in an
