Hi, I'm doing item similarity for recommendations. I would like to provide two kinds of recommenations for items: 1. similar item. I want to recommend anonymous user items similar to current item. 2. look with item. Recommend items which other anonmous users look with current item.
What appoaches can be used? I did more than 50 tries and don't get quite good result... :( I have 3*10^6 items and 3*10^6 anonymous users per day with item browsing history.
