"SMOTE resampling"

In777

This question was already asked in 2011. Is there any RM operator(s)/extension for SMOTE resampling?

If not, I have to use Scripting. Unfortunately, I do not know how create build-in R/Python Scripts for SMOTE. If anybody could share the script I will appreciate it a lot.

Unfortutnately, I don't have a SMOTE Process but you can try to make it yourself in R here: http://amunategui.github.io/smote/

 

That said, there isn't a native SMOTE sampling operator in RapidMiner. Maybe there should be.

 

I think the immediate route is to write it in R or Python and then maybe post this as an idea for the fine RapidMiner developers to write!

Thank you for the link, Thomas. I am not sure that I can implement this procedure in Python or R myself. I was hoping to find some less complicated solution. Can anybody help?

This is a pretty handy thing to have actually, I might write a building block for it this week if I have some free time.

It would very nice of you. I appreciate it a lot.
