Rapidminer Sample Process - Multiply Data

Posted on Mo 23 Januar 2012 in misc • 1 min read

I often use the Multiply operator to make copies of my data set and feed it into different learners. I do this because sometimes I don't know if a Neural Net operator, or a SVM operator, give me better performance.  Once I know which operator performs my task better, I then use the parameter optimization process to see if I can squeeze more accuracy out it.

The sample process below uses the Iris data set, just switch it out with your data set and enjoy.
