Model Comparison tool with Random Forest

Meteor

Hi,
    I have incorporated the Model Comparison tool into my workflow as I was not getting sufficient report output from the Random Forest tool,
(eg no confusion matrix)

I'm now getting an error with the Model Comparison tool and have no idea what the problem is ;

"Tool #153 Record #1 Tool #17 Tool #6 No Valid fields were selected"

Any ideas on what is causing this?

thanks!

Could you share some screen shots of how everything is configured!

And if you can replicate the issue with non sensitive data that would be great too.

Hi!

 

What kind of predictive problem are you solving? Is it a classification or a continous numeric problem? What I can see on my side is that the Model Comparison is throwing this error when you try solve a numeric problem, it does not throw the error for a classification problem. The error seems to come from the "Confusion Matrix" macro inside the Model Comparison tool, which makes sense actually because the Confusion Matrix is really only important for classification problems.

 

Now for numeric problems you should be able to ignore the error as you should still actually see results coming out of the P, E and R (with Browse for R) output anchors of the Model Comparison tool.

 

I will check with the Alteryx product team on this.

 

Best wishes

Oliver
