Hi all,
In the current implementation of the decision tree, data is split according
to the criterion of the form:
some feature some threshold
Is there a way use more general form such as:
some feature = some value or
F(feature) some threshold
where F is a function of the features.
It would be

You can replace the features with their F values in X for the latter.
Any reason not to do that?
Dear Caleb,
The current implementation does not allow for that. You can do as suggested
by Lars though, if this is practical for you.

Of course, some feature = some value can also be expressed as F(some
feature), so really, moving all of the feature transformation up front
should allow you to do everything you suggested. I understand the
convenience of using custom functions in some cases, but at least the
workaround here is
