During my travels I had to calculate some values given certain conditions. Appallingly I was unable to find any instance of Bayesian networks implemented in pure Tcl. The closest thing I found was [Bayesian Spam Filtering] by [Donal Fellows], which calculated probabilites by examining token frequencies. What I needed was a more general purpose network that could handle an arbitrary depth network. To remedy said condition and with the aid of Eliezer Yudkowsky's outstanding Bayesian Reasoning tutorial ([http://yudkowsky.net/bayes/bayes.html]) I went out and wrote one myself. Here is a trivial example of what Bayesian networks can do. In our fictional world there are exactly 100 --- Return to [Jason Tang] --- [Category Mathematics] | [Artificial Intelligence with Tcl]
