How can I record result description?

KHK

The Find threshold operator is an operator that automatically finds the appropriate threshold.

I wanted to store this threshold in Log and print it out with the results of the model, but in Log I couldn't get the threshold found by the Find threshold operator.

So, I want to get the contents of the description of the Find threshold, but I don't know how yet.

Please help.

Hi,

the Coverters Extension has an operator to convert thresholds. Not sure about the name, but after installing you should be able to just search for threshold.

Cheers,

Thank you for your answer.

I haven't been able to find an operator with that role, but it seems that I came up with a solution of my own by combining operators included in converters.

Thanks again.

Hi @KHK ,

great to hear. which operators did you use?

Fundamentally, I didn't need to print the thresholds for every model's equation created.

So we adopted a method to see the threshold for the result of learning data with the equation by obtaining the equation id obtained as the log result of the best model created by attaching the threshold to model operator after the find threshold operator.

It may seem cumbersome, but this wasn't a problem as it went hand in hand with another process of interpreting the model.

Thanks for your attention!

Hi @KHK ,

thanks! I checked it and you are right, converters does not help here. We may add it in future. In case someone stumbles upon this thread, here is a script to convert the threshold into a document. That helps you to at least parse it if you need it.

Best,

Martin
