New GFD-GC framework enhances graph fraud detection with GNNs

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a new framework called GFD-GC to improve graph fraud detection using Graph Neural Networks (GNNs). This method addresses challenges posed by incomplete node attributes and imbalanced datasets. GFD-GC utilizes group-wise aggregation to derive comprehensive node features and employs a confidence-aware contrastive learning strategy to augment limited fraud data with high-confidence pseudo-fraud nodes. Experiments show GFD-GC outperforms existing methods in detecting graph fraud. AI

IMPACT This research offers a novel approach to enhance fraud detection in digital ecosystems by improving GNN performance on incomplete and imbalanced graph data.

    A Novel Graph Fraud Detector via Grouped Attribute Completion and Confidence-Aware Contrastive Learning

    Graph fraud detection plays a pivotal role in safeguarding the security and integrity of modern digital ecosystems. Graph Neural Networks (GNNs) are commonly adopted for graph fraud detection. However, the practical performance of existing GNN-based detectors is severely hindered…
