  3. Graph Analytics & Network-Based Fraud Detection

    5 weeks
    Goals
    • Model fraud networks as graphs using Neo4j or NetworkX
    • Apply community detection, centrality analysis, and node embedding techniques to uncover fraud rings
    • Understand entity resolution and how shared attributes (IP, device, phone number) link fraudulent accounts
    Resources
    • Neo4j Graph Data Science certification
    • Stanford CS224W - Machine Learning with Graphs (selected lectures)
    • Project: IEEE-CIS dataset extended with synthetic graph features
