Artificial intelligence is a consortium of data-driven methodology that includes artificial neural networks, genetic algorithms, fuzzy logic, probabilistic belief networks and machine learning as its components. This book is the result of selection of high quality paper presented at a special session entitled 'Applications of Artificial Intelligence in Economics and Finance' at the '2003 International Conference on Artificial Intelligence '(IC-AI '03) held in Monte Carlo Resort, Las Vegas, Nevada, United States, 23 to 26 June 2003. Special Session, organized by Jane Binner, Graham Kendall and Shu-Heng Chen, presented in order to draw attention to the extraordinary diversity and richness of applications of artificial intelligence to problems in Economics and Finance. This volume should appeal to economists interested in adopting an interdisciplinary approach to studying economic problems, computer scientists are looking for potential application of artificial intelligence and practitioners who seek a new perspective on how to build models for everyday operations.
