"SVM classifier visualization"

dkopiec

I'm writing master thesis about pattern classification using SVM and one part of my thesis describes learning SVM. I would like to attach simple example with 2-dimensional input space and couple learning vectors split to to classes.

I wanted to show how SVM will split input space to these classes show chart like one of these:

or

in other words i wanted to plot value of y(x; w, b) - and marked positions of learning vectors.

How can I get such plot in Rapidminer?

Hi,
switch to the support vector table and choose the plot view. Then select your two dimensions for the axis and select the alpha value as color in the scatter plot Color.
