Banking — Machine Learning Model Training for Fraud Detection

Overview

The primary purpose of this DAG is to train machine learning models that can effectively detect fraudulent activities within financial transactions. It ingests data from multiple sources, including transaction logs, customer profiles, and historical fraud cases. The ingestion pipeline involves data preprocessing steps such as normalization, feature extraction, and data splitting into training and testing datasets. During processing, the DAG employs various algorithms to train the models, followe

The primary purpose of this DAG is to train machine learning models that can effectively detect fraudulent activities within financial transactions. It ingests data from multiple sources, including transaction logs, customer profiles, and historical fraud cases. The ingestion pipeline involves data preprocessing steps such as normalization, feature extraction, and data splitting into training and testing datasets. During processing, the DAG employs various algorithms to train the models, followed by rigorous performance evaluation using metrics such as accuracy, precision, and recall. A key aspect of this workflow is the monitoring of model performance; if there is a significant drift in metrics, an automated retraining process is initiated to ensure the models remain effective. The outputs of this DAG include trained models and performance reports, which are made accessible via an API for seamless integration with existing banking systems. Monitoring KPIs include model accuracy, false positive rates, and response times to detected anomalies. The business value of this DAG lies in its ability to enhance fraud detection, reduce financial losses, and improve customer trust in banking services.
