Hi all!

I would like to know if it is possible to see which ones of the examples in a training set (or more in general in any example) are "assigned" to which leaf in decision trees. I've been looking for a way to identify leaves of decision trees and for a way to see the association between examples and leaves but I couldn't find it. The only information I can get is the number of examples of each category in the training set that are assigned to a specific leaf but not exactly which ones. Is there an obvious solution to this problem that I can't see? If not, is this a feature that is going to be part of a future release of RapidMiner?
Thanks a lot.

Hi,
this is a little bit tricky, since we are not storing this information within the tree in order to reduce the memory consumption. I'm not quite sure if it's possible to add it afterwards. I will discuss this with the other developers.

Greetings,
