Application of Machine Learning in Fraud Detection for Banking Transactions

Thesis Abstract

Abstract
The banking industry plays a crucial role in the global economy by providing financial services to individuals and businesses. However, the rise of fraudulent activities in banking transactions poses a significant threat to the security and stability of financial institutions. In response to this challenge, the application of machine learning techniques has emerged as a promising approach to enhance fraud detection capabilities in the banking sector. This thesis investigates the effectiveness of machine learning algorithms in detecting and preventing fraudulent activities in banking transactions. Chapter One provides an introduction to the research topic, discussing the background of the study, problem statement, objectives, limitations, scope, significance, and structure of the thesis. The chapter also includes a comprehensive definition of key terms relevant to the study. Chapter Two presents a detailed literature review that explores existing research on fraud detection in banking transactions and the application of machine learning algorithms in this context. The chapter critically examines various studies, methodologies, and technologies used in fraud detection and highlights the gaps in current research that this thesis aims to address. Chapter Three outlines the research methodology employed in this study, including data collection methods, sampling techniques, data preprocessing, feature selection, and the implementation of machine learning models for fraud detection. The chapter also discusses the evaluation metrics and validation techniques used to assess the performance of the machine learning algorithms. Chapter Four presents the findings of the research, including the experimental results of applying different machine learning algorithms to detect fraudulent activities in banking transactions. The chapter analyzes the performance of each algorithm, compares their effectiveness, and discusses the implications of the findings for improving fraud detection systems in the banking industry. Chapter Five concludes the thesis by summarizing the key findings, discussing the contributions of the study to the field of fraud detection in banking transactions, and highlighting the practical implications for financial institutions. The chapter also provides recommendations for future research and the implementation of machine learning-based fraud detection systems in the banking sector. Overall, this thesis contributes to the advancement of fraud detection capabilities in banking transactions through the application of machine learning techniques. By leveraging the power of artificial intelligence and data analytics, financial institutions can enhance their security measures and protect customers from fraudulent activities, ultimately fostering trust and confidence in the banking system.
