Summary:
Graph structures effectively model complex relational data across many domains. Tudor and Jia demonstrate the application of Graph Neural Networks (GNNs) on fraud detection in Trustpilot by modeling the intricate relationships between businesses and consumers. Their work showcases how GNNs can capture the complex patterns of fraudulent activities that traditional methods often miss. Additionally, they discuss model explainability, ensuring that the learnings of our GNN align with domain expertise.
