This is a tutorial for those who are not familiar with Weka, the data mining package was built at the University of Waikato in New Zealand. Weka is an open source collection of data mining tasks which you can utilize in a number of different ways. It comes with a Graphical User Interface (GUI), but can also be called from your own Java code. You can even write your own batch files for tasks that you need to execute more than once, maybe with slightly different parameters each time.
