Thesis Overview

The project titled "Application of Machine Learning in Insurance Fraud Detection" aims to investigate and implement machine learning techniques in the field of insurance to enhance fraud detection processes. Insurance fraud is a significant issue that leads to financial losses for insurance companies and policyholders. Traditional methods of fraud detection often fall short in identifying sophisticated fraudulent activities, making it crucial to explore more advanced and efficient approaches. Machine learning, a branch of artificial intelligence, has shown promise in various industries for its ability to analyze large volumes of data, identify patterns, and make predictions. By leveraging machine learning algorithms, this research seeks to develop a robust fraud detection system that can effectively detect fraudulent activities in insurance claims. The research will begin with a comprehensive literature review to explore existing studies, methodologies, and technologies related to fraud detection in the insurance sector and machine learning applications. This review will provide a solid foundation for understanding the current state of the art and identifying gaps that can be addressed through the proposed research. The methodology chapter will outline the research design, data collection methods, selection of machine learning algorithms, and evaluation metrics. The research will involve collecting and analyzing insurance data sets to train and test machine learning models for fraud detection. Various machine learning algorithms such as decision trees, random forests, support vector machines, and neural networks will be implemented and compared to identify the most effective approach. The discussion of findings chapter will present the results of the experiments conducted to evaluate the performance of the machine learning models in detecting insurance fraud. The findings will be analyzed to assess the accuracy, precision, recall, and other relevant metrics to determine the effectiveness of the proposed approach. In conclusion, this research aims to contribute to the field of insurance fraud detection by demonstrating the potential of machine learning techniques in improving fraud detection accuracy and efficiency. By developing a reliable and scalable fraud detection system, insurance companies can mitigate financial risks associated with fraudulent activities and enhance trust among policyholders. Overall, the project "Application of Machine Learning in Insurance Fraud Detection" seeks to bridge the gap between traditional fraud detection methods and advanced machine learning technologies to create a more effective and proactive approach to combating insurance fraud.
