hi,

I have several performance inputs to an aggregate operator, now I get the average of them at the output port.. but how can I log them in log operator? there is no parameter or value field to log the average ?!?!

    Hi,

     

    you might want to try Extract Log Value.

    I can't use extract log operator, as it expects attribute name.. and  aggregate does not give any, it has even no named fields for performance, it just outputs the performance vector...?

    Hi,

     

    I am a bit confused: are you using the operator "Aggregate"?  Then the result is an example set and "Extract Log" should work.  Or did you use the operator "Average" on multiple performance vectors?  In this case you can use "Performance to Data" first followed by "Extract Log".

     

    Cheers,

    I used average, because aggregate weirdly accepts only 1 input ...

    but it still did not work, I wanted to append the average performance vector in each run of my  manual X-Validation (inside a grid optimization) to an example set, but I only get the last averaged performance vector of one run (last run) from the X-validation...
