The primary purpose of this DAG is to analyze customer data for identifying anomalous behavior that may signal fraudulent activities within the telecom sector. It ingests various data sources, including customer transaction logs, call detail records, and account activity reports. The ingestion pipeline is designed to ensure seamless data flow into the processing environment, where machine learning algorithms are applied to classify transactions based on risk levels. The processing steps include data cleaning, feature extraction, model training, anomaly detection, and risk scoring. Quality controls are implemented to ensure data integrity and model accuracy, with performance metrics such as precision, recall, and F1 score monitored continuously. The final outputs consist of classified transaction reports, risk assessment summaries, and alerts for further investigation. Additionally, a recovery mechanism is in place to handle any processing failures, ensuring system resilience. The business value of this DAG lies in its ability to reduce fraud losses, enhance customer trust, and optimize resource allocation for fraud investigations.
