Node Prediction Fusion

I am currently trying to get the new node "Prediction Fusion" to work. All I seem to get is a column added with "?". The only reference I can find on the website is in the nodepedia

https://www.knime.org/nodepedia/analytics/meta-learning/combining-classifiers-using-prediction-fusion

This does not show any settings and I am not able to download the example. So I can not examine it. Any hints or tips would be greatfully recieved.

Hello roblake44,

"?" stands for a missing value. Probably the reason is that you did not specify the classes and the confidence of the predictors.

Maybe this short introduction helps you: What's new in KNIME 3.1.

If not please upload a screenshot of the configuration dialog or even better: a sample workflow demonstrating your problem.

Best,
Ferry
