AbstractOutput. What are the principal release branches of Weka? Where can I get old versions of WEKA? How do I get the latest bugfixes? Can I check my CLASSPATH from within WEKA? Machine learning is a fascinating study, but how do you actually use it on your own problems? You may be confused as to how best prepare your data for machine learning, which algorithms to use or how to choose one model over another. In the interactive WEKA interface you select the learning method you want from a menu. o crossValidateModel(Classifier, Instances, int): Performs a (stratified if class is nominal) cross-validation for a classifier on a set of predict the performance of their students so as to improve their academic results. 4 years ago. supervised.
