Combine performance vectors into one average pv, and log it?
I tried to combine several performance vectors into one, and get the average performance vector, thats possible with the average operator...
however when I try to log the avg perf vector, there is no way to do it?? I cannot generate attribute out of it, and it apparently has no field "performance" from the average operator that could be logged... I hope thats a bug, not a feature...
I also cannot use extract log operator, as it expects some named attribute..
here is a picture of what I was trying to do, basically I did a manual 5-fold X-Validation and want to average the train and test-performances of each run into one:
I could just connect the output port of the average to the results set, however, I want to log it as there are multiple runs when I do this in a grid optimization with different parameters, and otherwise, I only get the last output of the average perf vector...
