Hi!

The core of RapidMiner is open source and available on Github.

This is the source code of the Neural Net operator.
https://github.com/rapidminer/rapidminer-studio/blob/master/src/main/java/com/rapidminer/operator/learner/functions/neuralnet/ImprovedNeuralNetModel.java

I'm not a Java developer, but it looks to me like a range transformation between 0 and 1 (initInputLayer function).

Also, if you aren't happy with this normalization function, you have the option to do your own normalization using one of the other methods using the Normalize operator prior to applying the NN operator (and then don't select the normalize parameter there).
