Subject Re: Exclusing certain ratings when running recommender

What do you mean "original items"? The user's preferred items are already
not candidates for recommendation, but that is nothing to do with the
rescorer. It operates on all *candidate* items, *before* scoring.

What is your distinction between filtering *recommended* items and
*original* items? Either way it is filtered. I don't understand what you
are getting at.
