Development of a Machine Learning-based Fraud Detection System for Insurance Claims

Thesis Abstract

Abstract
This thesis delves into the development of a Machine Learning-based Fraud Detection System tailored for the insurance industry. The insurance sector is vulnerable to fraudulent activities, which can result in substantial financial losses for insurance companies. Traditional methods of fraud detection often fall short in identifying complex fraudulent patterns in insurance claims. Hence, there is a pressing need for advanced technological solutions to combat insurance fraud effectively. Machine Learning, a subset of artificial intelligence, has shown promise in enhancing fraud detection capabilities by analyzing vast amounts of data to uncover suspicious patterns and anomalies. The primary objective of this research is to design and implement a robust Machine Learning-based Fraud Detection System specifically for insurance claims. The study begins with a comprehensive review of existing literature on fraud detection, machine learning techniques, and their application in the insurance domain. This literature review lays the foundation for understanding the current state of fraud detection in insurance and the potential benefits of leveraging Machine Learning algorithms for improved accuracy and efficiency. Following the literature review, the research methodology section outlines the approach taken to develop the Fraud Detection System. The methodology encompasses data collection, preprocessing, feature engineering, model selection, training, and evaluation. Various Machine Learning algorithms such as decision trees, random forests, support vector machines, and neural networks are considered and compared to identify the most suitable approach for detecting insurance fraud. The discussion of findings section presents a detailed analysis of the results obtained from the Machine Learning models applied to real-world insurance claim data. Performance metrics such as accuracy, precision, recall, and F1 score are used to evaluate the effectiveness of the Fraud Detection System in identifying fraudulent claims while minimizing false positives. In conclusion, this thesis highlights the significance of employing Machine Learning techniques in developing advanced fraud detection systems for the insurance industry. The proposed Fraud Detection System demonstrates promising results in detecting fraudulent activities, thereby enabling insurance companies to mitigate financial risks associated with fraudulent claims. The research contributes to the ongoing efforts to enhance fraud detection capabilities in insurance and underscores the potential of Machine Learning in combating fraudulent activities effectively.
