Anomaly Detection in Insurance Claims Using Machine Learning Algorithms

Thesis Abstract

Abstract
This thesis presents a comprehensive study on the application of machine learning algorithms for anomaly detection in insurance claims. The detection of anomalies in insurance claims plays a crucial role in identifying fraudulent activities, ensuring fair premium rates, and maintaining the financial stability of insurance companies. Traditional methods of anomaly detection rely on manual inspection and rule-based systems, which are often time-consuming and ineffective in handling the complex and evolving nature of fraudulent activities. Machine learning algorithms offer a promising solution by automating the detection process and adapting to new fraudulent patterns. The research begins with an introduction to the importance of anomaly detection in insurance claims and the limitations of existing methods. The background of the study provides an overview of the current challenges faced by insurance companies in detecting anomalies and the potential benefits of using machine learning algorithms. The problem statement highlights the need for more efficient and accurate anomaly detection techniques to combat insurance fraud effectively. The objectives of the study include developing and implementing machine learning models for anomaly detection, evaluating the performance of these models, and comparing them with traditional methods. The study also explores the limitations and challenges associated with using machine learning algorithms for anomaly detection in insurance claims. The scope of the study outlines the specific aspects of insurance claims that will be considered, such as fraudulent activities, false claims, and anomalies in claim patterns. The significance of the study lies in its potential to enhance fraud detection capabilities in the insurance industry, leading to improved risk management, reduced financial losses, and increased customer trust. The structure of the thesis is organized into five chapters, with each chapter focusing on specific aspects of the research. The definitions of key terms used throughout the thesis are provided to ensure clarity and understanding.
