Bug in Optimize Parameter operator?

Fred12

hi,

I was using k-nn inside optimize parameter (inside X-Validation) operator... and I was using euklidean and camberra distance for opt parameter settings...

but I noticed, that when using name "k-NN (2)" inside opt. parameter, it does not change the numerical_measure type... when I use a standard name "k-NN", it does change the parameters during running... seems to be a minor bug caused by the naming of the parameter as I experienced it?

ok here is a quick sample process where I used both k-NN:

in the one log the 2 distances show up, but not in the other:

Thanks@Fred12for the process. I've tested it with a lower compatability too and the problem is the same. I have pinged the developers.

Hi,

Thanks for pointing this out. Can you do us a quick favor and post the XML of a process using a data set from the Sample repository? This would allow our engineers to replicate and chase this bug.

Thanks,

Ingo
