[SOLVED] Generate Report for Naive Bayes result with Loop operator

vvossvvoss Member Posts: 2 Contributor I
edited November 2018 in Help
Hello,

I want to generate a report containing the result of a Naïve Bayes operator. Since the number of attributes varied for each process run, I want the automate the report generation for each attribute with a loop operator. The “Loop Attributes” operator however seems not to be able to handle this report generation. There is an error message “Expected ExampleSet but received KernelDistributionModel”.

Can any of the available loop operators handle the KernelDistributionModel?

Is there an alternate approach to implement a report generation for each attribute in the KernelDistributionModel with some kind of loop operation?

Best Regards,
Volker Voß

    Hey,

    instead of looping the naive bayes model you can loop the example set on which the model is created.

    Here is the corret process:
