Thesis Abstract

Abstract
Fraud detection in insurance claims is a critical challenge faced by insurance companies worldwide. Traditional rule-based systems are often insufficient in detecting sophisticated fraudulent activities, leading to significant financial losses for insurers. This thesis investigates the application of machine learning techniques to enhance fraud detection in insurance claims processing. The primary objective is to develop a robust and accurate fraud detection system that can effectively identify fraudulent claims while minimizing false positives. The study begins with an in-depth exploration of the background of insurance fraud, highlighting the prevalence and impact of fraudulent activities on the insurance industry. The problem statement addresses the limitations of existing fraud detection methods and the need for innovative solutions to combat fraud effectively. The objectives of the study are outlined to guide the research towards developing a practical and efficient machine learning-based fraud detection system. The literature review chapter provides a comprehensive analysis of existing research on fraud detection in insurance claims. Ten key areas are explored, including the use of data mining techniques, anomaly detection, and predictive modeling in fraud detection. The review also examines the challenges and limitations of current approaches and identifies opportunities for improvement through machine learning. The research methodology chapter outlines the approach taken to design and implement the fraud detection system. Eight key components are discussed, including data collection and preprocessing, feature selection, model training and evaluation, and performance metrics. The methodology aims to leverage the strengths of machine learning algorithms to enhance the accuracy and efficiency of fraud detection. The findings chapter presents a detailed discussion of the results obtained from applying machine learning algorithms to detect fraudulent insurance claims. The analysis includes the performance evaluation of different models, comparison of accuracy rates, and the identification of key factors influencing fraud detection outcomes. The findings contribute to the understanding of the effectiveness of machine learning in detecting insurance fraud. In the conclusion and summary chapter, the overall implications of the study are discussed, highlighting the significance of utilizing machine learning for fraud detection in insurance claims. The conclusions drawn from the research findings are summarized, and recommendations for future research and practical applications are provided. The thesis concludes with reflections on the contributions of the study and the potential impact on improving fraud detection practices in the insurance industry. In conclusion, this thesis offers valuable insights into the application of machine learning for fraud detection in insurance claims. By leveraging advanced algorithms and techniques, insurers can enhance their capabilities to identify and prevent fraudulent activities effectively, thereby safeguarding their financial interests and maintaining trust with policyholders.
