Project: The goal of this project is to analyze data anomalies in the context of credit card data. Based on anonymized credit card transactions, time series patterns need to be analyzed in order to detect payment fraud. Based on both statistical and machine learning approaches, competing fraud detection models will be investigated. As a result, the applied approaches will be compared with respect to accuracy, complexity and feasibility. Additionally, the results will be visualized. You will work together with experienced data scientists and you will learn in this project how to visualize and to communicate results within a heterogeneous team. Furthermore, you will get deep insights into the challenges that practitioners are facing, especially when the achieved solutions to such real-world problems need to be implemented into applied risk management processes.
