You can also simply use "Select Attributes" and only pass through attributes that you want to consider for modeling inputs into any machine learning operator. This will make sure that any items that are not appropriate don't end up in a model. You can join the dataset back to a copy of itself to re-add those attributes later if you want them for reporting purposes.

Did you check the "Weight by User Specifications" operator? This helps us assign weights for attributes (Variables).

Hope this helps.
