Thesis Abstract

Abstract
The insurance industry faces significant challenges in detecting and preventing fraud in insurance claims. Fraudulent claims impact the financial stability of insurance companies and can lead to increased premiums for honest policyholders. In recent years, the integration of machine learning algorithms has shown promise in enhancing fraud detection capabilities in various industries. This thesis investigates the implementation of machine learning algorithms for fraud detection in insurance claims. The study begins with a comprehensive review of the existing literature on fraud detection in insurance and the application of machine learning algorithms in fraud detection. The research methodology encompasses data collection, preprocessing, feature selection, model training, and evaluation. A dataset containing historical insurance claims data is used to train and test different machine learning models, including decision trees, random forests, and neural networks. Performance metrics such as accuracy, precision, recall, and F1 score are used to evaluate the effectiveness of the models in detecting fraudulent claims. The findings reveal that machine learning algorithms exhibit promising results in detecting fraudulent insurance claims. The random forest model emerges as the most effective in identifying fraudulent claims, achieving an accuracy of over 90%. Feature importance analysis indicates that variables such as claim amount, policyholder age, and claim type significantly impact the likelihood of fraud. Furthermore, the study explores the interpretability of machine learning models and discusses the challenges and limitations associated with implementing these models in real-world insurance settings. In conclusion, the implementation of machine learning algorithms for fraud detection in insurance claims offers a valuable tool for insurance companies to enhance their fraud detection capabilities and mitigate financial losses due to fraudulent activities. The study underscores the importance of continuous monitoring and updating of machine learning models to adapt to evolving fraudulent tactics in the insurance industry. Future research directions include exploring advanced machine learning techniques and incorporating external data sources to further improve fraud detection accuracy.
