In this lecture, we explore Step 4 of implementing Self-Organizing Maps (SOMs) for fraud detection in credit card applications. We dive into the process of mapping winning nodes to customer data, a crucial step in identifying potential cheaters. Using Python and the MiniSom library, we demonstrate how to create a dictionary of mappings between winning nodes and customer data. We then focus on identifying outlier nodes and extracting the corresponding customer information. The lecture covers practical implementation details, including the use of NumPy's concatenate function and inverse scaling techniques to obtain the final list of potential fraudsters. By the end of this session, you'll understand how to leverage SOMs for anomaly detection in real-world scenarios, combining machine learning and data science techniques to uncover patterns in complex datasets.
