Hello,
could anyone give me an example how the WeightedPerformanceCreator should be used. Unfortunately, the code below returns "unknown" performance value.
Below I have made an example (which is a part of XValidation) where the default weight is 0.0 and the weight of "accuracy" and "relative_error" were explicitly set to 1.0 resp. 2.0. I do nut undersand why the resulting performance vector returns unknown.
Thank you in advance.
