Hello, I have database with ratings: 1,2,3,4
However, when running the recommender I would, in some cases, want to exclude items with rating 4. I considered IDRescorer but reckon that it only filters items after the recommender has has already recommended. I would like items filtered before recommendations i.e. they should not be included when calculating recommendations. What's the best way of handling this in mahout? Thanks. Mugoma.
