"Bayesian inference techniques have been widely used in developing various types of Artifical Intelligence (AI) systems (for instance for text retrieval, classification, medical diagnosis, data mining, troubleshooting, and more), so this article series will be of interest to anyone interested in building intelligent Web applications.

"In this article, I will introduce some of the basic mathematical concepts and notations you need to know in order to appreciate Bayesian inference. I will also demonstrate how you can implement conditional probability and Bayes theorem calculations using PHP, and how these calculations can be used to build an online medical diagnosis wizard.
