Find Threshold (Meta) Operator...

Fred12

hi,

can someone explain me how that operator works?

I use it with trainingdata and model inside, and I get a better performance than without using it, however, there is no threshold value output... how do I know what the classification threshold value should be? and what value is it? is it the confidence / or probability output of the learner? I use LibSVM Learner...

Good question, I never use that operator and just do the cost modeling inside a Cross Validation operator directly and then pass the Threshold out. Maybe @Marco_Boeck knows?
