ABSTRACT
Decision making forms the core of any AI system. There are many different approaches to decision making, several of which are discussed in other chapters in this book. One of the most robust and powerful systems we’ve encountered is a utility-based system. The general concept of a utility-based system is that every possible action is scored at once and one of the top scoring actions is chosen. By itself, this is a very simple and straightforward approach. In this article, we’ll talk about common techniques, best practices, pitfalls to avoid, and how you can best apply utility theory to your AI.
