Train Test Split in VA Models

znhnm — Wed, 22 May 2024 07:01:10 GMT

Hello,

I am building models on VA interface. Is it possible to do a 80/20 train/test split in this interface? Or do I need to use SAS Studio or VDMML pipelines to do that split?

Thank you!

Hey @znhnm! You can do a train-validation-test split directly in VA:

In the Data Pane, click New Data Item
Select "Partition"
Choose your sampling method:
You now have a partition data item that you can use in models. Add this to the "Partition" role in the Roles panel for the model:
You'll see the model with train-validation split in the model:

The model will automatically be tuned based on the results of the split. Easy-peasy!
