DatabaseExampleSource: Metadata
Hi there,
I'm quite new to RapidMiner, but have some experience with SAS Enterprise Miner. I already set up a Decision Tree learning process and got some exciting results (well at least judging how they look
).
But what I'm missing now is the following:
In SAS Enterprise Miner you can tweak the variable roles on every node - like setting it to "ignore", "target" or whatever. I use a DatabaseExampleSource and when using the Database wizard I can set up the roles once - but after that I don't manage to get back to change those roles without doing the whole wizard again. What's the right approach to change the roles of variables from a DatabaseExampleSource? And is there a node type which can be used to do this?
Thanks again in advance and for this great piece of software.
