Augmentation Randomization/Multiply
Any ideas how can I do a randomization with multiply or any way to the an augmentation with my dataset which only has 170 rows ?
The reason is that I need to do a split-test- validation and my dataset ist not big enough for that purpose!

I would recommend exploring weighting as a solution to imbalanced, small datasets. The other alternative is to us one of the upsampling operators from one of the free extensions.
Altair EmployeeHi @Sunnyboy_nh ,
Another way is to use the Build Simulation operator, which is part of Operator Toolbox.

Thanks Martin and Telcontar120 for your feedbacks and suggestions. Meanwhile I have looked at a similar operator in Rapidminer called Sample(Bootstaping) before Split Data Operator does that data augmentation by copying the exisiting rows.
Nevertheless I will try to check your suggestions as well
