Indentifying and eliminating insignificant attributes
Learner III
Hello!
Within statistics we usually operate with a 5% significance value for determining which attributes are significant or insignificant in the model. Thereby one can remove insignificant attributes and get a "simpler" model. How would one go ahead doing this in Rapidminer and is there an automated process for it?

I'm not aware of an implementation of the feature your describe in RapidMiner.
But more generally, what you describe - get a "simpler" model - is called feature selection.
In RapidMiner you can apply feature selection by :
- Enabling Automatic Feature Selection and choosing your option (simple/balanced/accurate) in Auto-Model.
- Using directly in your process the Automatic Feature Engineering operator.
- Using the feature weights operator(s) (Weight by Information Gain, Weight by Correlation etc.) associated with the Select by Weights operator.
Hope this helps,
Regards,
