Exploring the Experimenter

Ian Witten shows how to use the Experimenter to find the performance of classification algorithms on datasets.

Learn how to use Weka’s Experimenter interface. It makes it easy to run different algorithms on different datasets and compare the results – whether one classifier is better than another on a particular dataset and whether the difference is statistically significant or not. The results of these tests can be output as an ARFF file – so you can do data mining on the results of data mining experiments!
