How to use widget "Test learners"

Postby sapienza » Mon Sep 24, 2007 17:51

I am a student. I am going to use these widgets:
- file
- data sampler
- cn2
- cn2 rules viewer
- test learners
- confusion matrix

the connections are:
file -> data sampler
data sampler->cn2, test learners
cn2->cn2 rules viewer, test learners
test learners->confusion matrix


The file is a .tab file in which there are attributes with discrete and continuos value. The confusion matrix is always empty. Can you explain me what is the problem?

I've tried with iris.tab example and it works, i don't understand why in my example it doesn't work. Maybe for the values of attributes, continuos and discrete?Thanks for the help

There was another post you overlooked. :)

The problem has already been fixed, just download the latest snapshot.

thanks for the answer janez, i've posted in the other topic, and i've downloaded the newest version today, re-installed, but it gives the same problem and the same error. I don't know, i'll try again to re-install Orange. thanks
