[SOLVED] How to remove features that appear rarely in training data?
Hello,
I am using RapidMiner to classify some documents. Currently I want to apply a very simple feature selection technique, but I cannot find a method to do it. ???
I just want to remove all attributes that appear less than four times in the trainingdata. Does anyone know which operator I will need?
Thanks for the help. 8)
