I have been using KNIME for building classifiers.
I thought the basic thresholds for any classifiers should be 0.5, but recently noticed that some predictions from RProp MLP Learner node are labeled as class 1 with probabilities below 0.5 (something between 0.4 and 0.5).
I could not find any way to check the set threshold and how to even change it.
Can someone help me with this issue?
