Data Table Widget Reports "No Data on Input"

Postby Nnanyelugo » Sat Jun 08, 2013 19:06

I did some classifications with some of the "Classify" widgets properly linked to the test learner and confusion matrix widgets for necessary evaluation. However every attempt I have made to see the classified examples with their classes returned "no data on input" from the data table widget. For instance I will like to see probability classifications on the the examples when I use the logistic regression widget. Please can someone let me know what I am doing wrongly.

Did you select any cells in the Confusion Matrix widget?
For instance, a simple scheme using File, Naive Bayes Test Learners and a Confusion Matrix connected to a Data Table works for me as long as the Confusion Matrix has some selected entries.

This is not possible using the Confusion Matrix widget, it only reports the predicted classes not the probability estimations. You might want to try the Predictions widget instead.
