Greetings
i´m having some issues with the scorer node in order to calculate the accuracy of a random forest model. The scorer doesn´t detect the predicted values column (although the numeric scorer one does it). A “first and second column cannot be the same” error appears because i can´t select the new column after RF predictor processing.
Have you tried simply to rename one of the columns? More importantly are you sure your predictor is actually producing a prediction column? Without being able to see your workflow its hard to determine what’s happening.
Another issue. Is your target data numeric or categorical? If its numeric, I don’t think the Scorer node will work. It calculates accuracy which doesn’t make sense with continuous numbers.
