Correctly Name The Oversample Field Tool

A quite minor, pedantic issue from me today. 


Currently, the Oversample Field Tool's naming and configuration suggest that the tool can over sample data:


However, I would argue the tool under samples data instead.

Here are a few sources that explain this much better than I can:

And an image is taken from Medium:


Effectively either step is to create a similar (or same) number of records between each class. Under sampling is the process of taking samples from the majority class, and ending up with a smaller dataset than started with. Over sampling is the process of duplicating records within the minority class, and creates a larger dataset.


When using the Oversample tool within Alteryx, using the example workflow for reference:


When summarizing the input:


And the output:


It's clear that the data has actually been under sampled, in that random samples have been taken from the majority class to match the minority, rather than creating duplicate minority records. 

I would suggest a quick renaming of the tool to "Undersample Field Tool", and documentation to not cause confusion to new users of the platform.

How about also adding in functionality to give the user the ability to chose whether they want to over or under sample their data?

Love the idea - I propose a dilemma... what do you then call the tool that can both over and under-sample data? 😂

I would also like a tool that provides the option of under or over sampling
