Many recommender systems use some type of average of weighted sums method. Last assume that I have two users A and B. I would like to make a prediction about user C. In known selections user A and C have 86% similar matching. Also in known selections user B and C have a 24% similar matching. In a new selection we know that user A gives select 3 and user B selects 5. What is the predicted selection for user C? [Show you equation and work.]
