[SOLVED] Local Polynomial Regression working only with real labels

aborg

Hello,

  I think this (Local Polynomial Regression requiring real labels) is a feature, but I am not not sure why it is not set to the required metadata of the operator input. So I am curious is there a combination of parameters which can handle nominal label in the input?
Here is a process failing only upon executiion (works fine with the [tt]//Samples/data/Polynomial[/tt] location):

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.2.008">
  <context>
    <input>
      <location>//Samples/data/Ripley-Set</location>

  </context>

      </operator>

      <portSpacing port="sink_result 2" spacing="0"/>
      <portSpacing port="sink_result 3" spacing="0"/>
    </process>
  </operator>
</process>

Here is the error message:

Thanks, gabor

Hi Gabor,

Local Polynominal Regression is not capable of handling nominal labels. You'll have to use another operator for that.

Concerning the metadata, I just created an internal ticket requesting to add the check to the metadata processing. Thanks for reporting!

Best regards,
Marius
