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.

    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 :)
