REAL-TIME DATA QUALITY ASSURANCE BY INTEGRATING AI-DRIVEN ANOMALY DETECTION, EXPLAINABLE AI, AND AUTOMATED ROOT CAUSE ANALYSIS FOR SUPERIOR DATA QUALITY IN THE ETL PIPELINES

Smart overview of the Invention

The patent application outlines a system designed to enhance data quality within Extract, Transform, Load (ETL) pipelines by employing an AI-driven approach. The system integrates machine learning to detect anomalies in source data before it is loaded into a target system. By analyzing these anomalies using Shapley Additive Explanations (SHAP) values, the system identifies contributing factors, ensuring that only validated data proceeds through the pipeline. This approach maintains application continuity and improves the overall data quality management process.

Background and Challenges

ETL pipelines are essential in transferring data from source to target systems, but they often face data quality issues that can disrupt operations. Traditional methods validate data post-load, which can lead to inaccuracies and inefficiencies. Poor data quality in target systems can result in faulty analysis, misleading reports, and increased costs due to manual corrections. The proposed system addresses these challenges by integrating real-time anomaly detection and analysis within the ETL process itself.

Innovative Approach

The system leverages a trained machine learning model to detect anomalies as data is processed through the ETL pipeline. SHAP values are utilized to explain the detected anomalies and identify their root causes, reducing the need for manual root cause analysis. This method ensures that only high-quality data is loaded into target systems, thereby preventing the propagation of errors and maintaining data integrity across various datasets.

Goals and Advantages

• Maintains high-quality data flow into centralized data warehouses or lakes.
• Provides a self-learning, intelligent system for real-time data quality assurance.
• Combines AI-driven detection with Explainable AI for in-pipeline monitoring.
• Reduces manual intervention by automatically analyzing root causes using SHAP values.
• Offers real-time data quality monitoring and stakeholder notifications for anomalies.

Implementation and Benefits

The system ensures business stability by operating on previously verified data while detecting new anomalies. It offers a transparent, proactive approach to anomaly detection, enhancing operational effectiveness and strategic decision-making. By utilizing a Random Forest classifier and feature engineering, the system calculates probability scores to identify anomalies, classifying them by risk levels. This innovative application of SHAP values in the ETL process provides stakeholders with clear insights into anomaly detection outcomes.
