Zusammenfassung der Kapitel (Chapter Summaries)

1. INTRODUCTION: This introductory chapter sets the stage for the dissertation. It establishes the necessity for improved consumer loan credit risk assessment, outlining the objectives of the research and the overall theme. The chapter also provides a brief overview of the report's structure, guiding the reader through the subsequent chapters. The introduction highlights the growing importance of accurate credit risk prediction in the financial sector and positions neural networks as a potential solution to improve existing methods.

2. LITERATURE SURVEY: This chapter provides a comprehensive review of existing literature on artificial neural networks and their applications, particularly in credit risk analysis. It begins with a discussion of the biological basis of neural networks, moving to their application in information processing systems. The chapter details the historical development of neural networks, contrasting their functionality with conventional computing. It explores various types of neural networks, focusing on feed-forward networks, backpropagation networks, and radial basis function networks, explaining the learning processes involved. The chapter concludes by establishing a theoretical foundation for the research methods employed later in the dissertation. The emphasis is on establishing a thorough understanding of neural network architectures, their strengths, and their limitations, especially when it comes to prediction problems.

3. DEVELOPMENT OF SYSTEM: This chapter focuses on the practical implementation of the credit risk analysis system. It provides an overview of MATLAB, the software used for development, highlighting its advantages and disadvantages for this specific application. A detailed explanation of the Neural Network Toolbox in MATLAB is given, outlining its key features and how it was utilized in the project. The chapter further describes the data preprocessing techniques applied to the dataset used for training and testing the neural network models. Crucially, it details the implementation of both the feed-forward backpropagation network and the radial basis function network, along with the learning algorithms used (TRAINRP). It concludes with a precise description of the developed consumer loan risk analysis system, setting the stage for the performance analysis in the next chapter. The detailed description allows reproducibility of the research.

4. PERFORMANCE ANALYSIS: This chapter presents the results of the experimental analysis conducted on the developed credit risk analysis system. It details the performance of both the feed-forward backpropagation and radial basis function networks, comparing their performance on different dataset sizes (500 and 44 records). A thorough comparison is made between the performance of these neural network models and traditional statistical methods for credit risk assessment. The chapter presents a detailed comparison of the results, examining training and testing accuracy, and discusses potential reasons for any observed differences in performance between the methods. Statistical measures are likely employed to support the analysis. The chapter concludes with a justification for any discrepancies found between the experimental and statistical methods, providing insights into the relative strengths and weaknesses of each approach.
