Subject Re: Exclusing certain ratings when running recommender

Filtering happens on "original items" if I understand you correctly.
Conceptually, it goes like...


   1. Candidate items are chosen
   2. (Optionally) Items are filtered
   3. Items are scored
   4. (Optionally) Items are rescored
   5. The top K are returned
