Generally speaking, we teach a machine such as a computer in order to understand and achieve a specific goal. This case is called machine learning. Varieties of programs are implemented in machines so they can make decisions. Machine learning consists of using various algorithms to build a decision system. In this book, I use fuzzy logic and Bayesian algorithms to make a decision system. I...
