Create a use case for the gallery about mlr3filters HOT 4 OPEN

I suggest using this dataset (5000 obs, 1k features)

from mlr3filters.

Are you suggesting it because of its dimension or because filtering works pretty well on it?

What about spam in mlr3?

from mlr3filters.

spam would also work I'd say. In the end the question is what the use case should show:

• compare filters against wrappers?
• compare single filters against ensemble filters?
• showcase the caching attribute of filters?

None of the above do really depend on the dataset unless you want to find a use case where features outperform wrappers.

Yes, my idea was because there are so many features.
I would prefer a regression task (because then I can use it for MaRDI), that would make spam less attractive for me.

Are there already benchmark studies on those questions @pat-s ?
In this case we could make a gallery-posts that gives some recommendations on what to do with filters?
I.e. giving the reader the answer to those questions :)
