One-hot encoding transformation method for class inputs is "missing"

EvelynLau — Sat, 26 Feb 2022 16:31:58 GMT

Hi,

I am using SAS Viya (specifically Model Studio) for my assignment.

I want to use the one-hot encoding under Transformation but it is not there in the Class Input (missing). May I know what is the reason that one-hot encoding is not on the list?

Many thanks in advance.

Hello,

Look at this 2018 article (to be found in the communities library) :

Class Variable One-Hot Encoding in SAS Visual Data Mining and Machine Learning

Good luck,

Hi @EvelynLau,

Do you know which version of SAS Viya you are using?

The one-hot encoding transformation method for class inputs was added to the Transformations node in SAS Viya Stable 2021.1.2 (June 2021) and Long-Term Support 2021.2 (November 2021). However, if you do not have access to those versions (or newer), then the article in the SAS Community Library that @sbxkoenk referenced is the recommended workaround.

Best,

-Brian

Hi @BrianGaines,

I am using this version.

Is this the latest version? If not, how do I get the latest or newer version?
I am still new in using SAS Viya.

Hi @EvelynLau,

Thanks for sending that screenshot. Based on that, you are currently using SAS Viya 3.5.

The version numbers that I referenced in my previous post are for Viya 4, so you are not using the latest version and your version does not have the one-hot encoding method in the Transformations node.

How do you access Viya? Is it through Viya for Learners, or another way (such as through an employer)?

Thanks,

-Brian

Hi @BrianGaines,

I am accessing Viya through Viya for Learners.

I guess based on your explanation, there is no way I can use the one-hot encoding method in the Transformations node except through coding.

Thanks for the information anyway and appreciate your time and assistance.

Have a good day.
