ID3Numerical Bug??

adaman

Hey,
i´m not sure if this is a bug, but i´m searching for a tree model which is updateable and as it is writen in the JavaDOCS http://rapid-i.com/api/rapidminer-5.1/com/rapidminer/operator/learner/tree/ID3NumericalLearner.html
the Class ID3NumericalLearner comes from the AbstractTreeLearner and should be updatable. But my little example shows, that it does not.

The first code is for creation of the model, the second for the update. I use the latest Version 5.1.006. If i´m wrong i would appreciate if s.o. can tell me if there is any tree which is updatable or how to use W-BayesNet so that i can update.

Thank you very much for the help and greetings

Hi,

you've posted the same code block twice..
Apart from that, where did you get the idea that the ID3NumericalLearner is updatable?
However there is an W-NaiveBayesUpdateable operator, which should be the one you're looking for.

Regards,
Marco
