Applying oversampling on training data through SAS Code Node on Viya

DataCrunch — Fri, 22 Jul 2022 15:20:48 GMT

Hello there!

Unfortunately, I cannot figure out the following challenge I currently face: I'm currently migrating some data modeling workflows to SAS Viya (3.5 and 4, working on both) and would like to use the Model Builders as extensively as possible. One of the models require a certain way of oversampling on the training data, which I would like to do through the SAS Code node. However, I seem to be unable to find out how I can work with the training data within the SAS Code node and oversample them accordingly and access the output in the child nodes for modeling.

Any help is greatly appreciated!

Hello @DataCrunch ,

You are migrating to Model Studio (Model ~~Builders~~) in VIYA 3.5 and VIYA 4 , isn't it?

And from where are your 'modeling workflows' coming?

From Enterprise Miner 15.2? Is EMiner the source and Model Studio the destination?

Have you done "a certain way of oversampling on the training data" in an SAS Enterprise Miner code node?

The logic between the code node in EMiner and Model Studio is quite similar.
Everything is in macro variables and macros such that nothing is hard coded.

Kind regards,

Koen
