Confusion matrix for WEKA decision trees

KNIME Analytics Platform

Hi guys,

is there a way of generating confusion matrix for WEKA decision trees? Something like this:

== Confusion Matrix ==
 
 a b   <-- classified as
 9 0 | a = yes
 0 5 | b = no
2

If you use the Weka Predictor and then the Scorer node, you will see the confusion matrix as part of the node view.

Thank you very much yes!
