Performance Average (Robust) - Process failed

svjo

Hi there,

我想计算的平均表现or multiple hold-out sets via the Performance Average (Robust) operator. Unfortunately I get a process failed message with a java.lang.RuntimeException: Clone of average vector is not supported: cannot clone averagable: … .performance.SquaredCorrelationCriterion.

Why is the Squared Correlation Criterion not accepted in this operator?


Cheers,
Sven

Looks like the issue arises when there are two performances that need to be averaged, especially for squared correlation. Here is the XML code I used to reproduce the error.@svjohow many performances are you trying to average? Cause I am unable to reproduce with more than 2 performances. Just asking to know.

I used a saved auto model process and copied the Performance for Hold-out sets and the performance average into my own process. So the standard criteria are used (RMSE, absolute error, relative error lenient, squared error and correlation). I added squared correlation to the list. I works if I leave squared correlation out.

thank you@varunm1!
