Indentifying and eliminating insignificant attributes
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 calledfeature selection.
In RapidMiner you can apply feature selection by :
——使Automatic Feature Selectionand choosing your option (simple/balanced/accurate) in Auto-Model.
- Using directly in your process theAutomatic Feature Engineeringoperator.
- Using thefeature weightsoperator(s) (Weight by Information Gain,Weight by Correlationetc.) associated with the选择的权重operator.
Hope this helps,
