"Decision tree : keep id"
Contributor II
Hello,
I'm trying to use decision tree on RapidMiner and I can't find how to keep id during the process. Here is an example of what I get on rapidminer:

Result :
Wind = falseIn the results, for each node, there is the number of occurrences for each values, but I need to get the id of each one. I mean I need to get this kind of result:

Wind = falseIs there a simple way to do this kind of thing with decision tree?
