This chapter provides some background information and motivation for this study. The rest of the report is divided roughly into two parts. Chapters 2 to 4 include the theoretical foundation on which the case study in Chapter 5 is built on. In Chapter 6 conclusions are presented.
Chapters on theoretical aspects of this work are not necessarily self-contained, but should offer the reader somewhat thorough and clear presentation of the main principles. Especially, Chapter 2 on the Self-Organizing Map is intended to give a thorough discussion of the basic principles. For further details, several references are listed in the text.
