Decision Tree

Hello,

i'm searching a tool to create a decision tree to solve a classification problem. I' ve tried the DecisionTree tool but the resultat of the classification isn't very good. Is there a possibility to define some of the decision rules manual? Can i solve this problem with a rule learner for which i can define the rules?

thanks,

Barbara

Hello Barbara

...DecisionTree tool ...

I assume you mean "operator"

Is there a possibility to define some of the decision rules manual?

As far as I know, this is not possible within RapidMiner. Data Mining is the automatic extraction of Rules, hence "guessing" rules is not an appropriate way, except the case you are a domain expert

Can i solve this problem with a rule learner...

Since I do know nothing about your data, the question is impossible to answer. If you are preferring rules I suggest to try more of the operators creating trees and rules. Beside the implementations provided by RapidMiner you will find more under the category Learner->Supervised->Weka.

hope this was helpful
