Introduction

Over the past 60 years, artificial intelligence has grown from a largely academic field of research to a ubiquitous array of tools and approaches used in everyday technology. Artificial intelligence technologies are virtually all around us—from sophisticated navigation systems and anti-collision sensors placed on cars to recommender systems meant to help us pick a book or movie. However, while great emphasis has been placed on improving the performance of such systems, certain meaningful facets have not been as thoroughly explored.
