[Solved] How to read out multiple performance parameters within optimization

User: "qwertz"

Hi,

In the attached process I have two different performance operators which run inside an "optimization" operator.
Now I am looking for a way to get the result of the whole process (both performance values of the optimized/best model) into an example set. This seems a little tricky as a kind of collection is returned but I cannot use the "append operator" as the type is "per" and not "exa". (Nor is it possible to log within the optimization operator as this would only return the last run of the SVM but not the optimized/best.)

Would appreciate any ideas...


Best regards
Sachs
