Impute Missing Value operator - Performance

Ellie98Ellie98 Member Posts: 27 Contributor II
Hello there,

I replaced some missing values with the operator "Impute Missing Values" using the KNN scheme. I also normalized it and wanted to check the performance and connect the "Performance" operator inside the "Impute Missing Value" operator but the connection doesn't work. 

Can't I use performance with the "Impute Missing Value" operator? 

Thanks in advance!

    You should be able to use any process inside Impute Missing Values that returns a model on the model output.

    If you're interested in the performance, you could connect the ave output of the cross validation to a Remember operator, set the io object type to PerformanceVector and then either put a breakpoint on the validation or use Recall later to retrieve the remembered performance value.
