new role, meta data!

wessel

Often I have some attributes which are only used to check if everything goes as planned.
So they should not be used by the learner.
To prevent the learner from using these attributes you can change the role to ID or batch or cluster,
but this is not really the intended purpose of the the change role operator.

Would be nice to have a roll "meta" which indicates this attribute should not be used, but should not be thrown away either.

Best regards,

Wessel

Hi,

actually, I typically just set the role to "ignored" (not that you can use arbitrary strings as role names). This way, you make sure that you don't confuse any operator by using a defined role. Still, it may be worth to introduce such an "ignored" role as a standard role name.

Cheers,
Simon

Hmm, the problem is, when I use the operator "windowing", the only special attribute that remains after windowing is 'id', all others are removed for some reason.

fischer

Which "windowing" operator are you referring to?

wessel

The operator is called "windowing" so not "windowing (series)"
