WebJul 10, 2024 · Anomaly detection on attributed networks aims to differentiate rare nodes that are significantly different from the majority. It plays an important role in various practical scenarios, such as intrusion detection and fraud detection. However, existing graph-based methods mainly adopt shallow models that cannot capture the highly non-linear … WebFraud Detection in Graph Neural Network. This repo is refactored from the model used in awslabs/sagemaker-graph-fraud-detection, and implemented based on Deep Graph Library (DGL) and PyTorch. Unlike Amazon's implementation, this repo does not require the use of Sagemaker for training.
