ABSTRACT
This project, Fraud Detection Analysis using Power BI, presents a modern approach to identifying and preventing fraudulent activities by combining advanced data analytics, machine learning, and interactive visualization. Traditional fraud detection methods, typically rule-based and static, often fail to keep up with the complexities of today’s data-driven environments. This study addresses these limitations by leveraging Power BI’s dynamic capabilities to create a responsive, scalable, and user-friendly fraud detection framework.
The project focuses on developing an analytical system that can detect irregular patterns and potential fraud in real-time. Through data collection, preprocessing, and exploratory data analysis, the system integrates heterogeneous datasets—such as transaction records and user activity logs—into a unified Power BI dashboard. These dashboards not only visualize data intuitively but also support decision-making with real-time insights.
By incorporating statistical techniques and machine learning algorithms, the project emphasizes anomaly detection and pattern recognition. Clustering and classification models help differentiate between normal and suspicious transactions, while Power BI’s visualization tools make the insights accessible to both technical and non-technical users. This dual functionality enhances fraud identification accuracy and reduces false positives.
Experimental validation using historical and simulated datasets showed that the Power BI-based system significantly outperforms traditional methods in detecting subtle fraudulent behaviors. The ability to monitor fraud in real time, combined with reduced error rates, highlights its practical utility across sectors like banking, insurance, and e-commerce.
This interdisciplinary project bridges data analytics, AI, and financial forensics, offering a flexible model adaptable to multiple industries. Future enhancements may include real-time data streaming and deeper machine learning integration to further improve detection capabilities. Ultimately, this study provides a robust, replicable solution for transforming raw data into actionable insights, advancing fraud detection in the modern digital landscape.
