The Automated Fraud Detection Model Retraining Pipeline is designed to continuously improve the accuracy and effectiveness of fraud detection models utilized in the public sector. The primary purpose of this DAG is to automate the retraining process based on the accumulation of new data and monitoring results, ensuring that the models remain relevant and effective in identifying fraudulent activities. The data sources include transaction logs, user behavior analytics, and historical fraud case data. The ingestion pipeline begins with the collection of these data sources, followed by preprocessing steps that clean and format the data for analysis. The next step involves training new models using advanced machine learning algorithms, which are then validated against established performance metrics to ensure their reliability. Quality control measures, such as cross-validation and performance benchmarking, are applied throughout the process to maintain high standards. Once the models are validated, they are automatically deployed into the production environment, ready to enhance fraud detection capabilities. Monitoring is implemented through key performance indicators (KPIs) such as model accuracy, false positive rates, and processing time, which provide insights into the effectiveness of the models in real-time. The business value of this DAG lies in its ability to reduce fraud losses, improve operational efficiency, and enhance public trust through timely and accurate fraud detection.
