Abstract In this paper, we propose a method for consolidating multiple matrices incrementally for recommendation system. Based on mathematical approach methods, we unify multiple matrices together based on the overlap of the utility matrix. Specifically, we suggest a procedure to consolidate matrices together. Then the recommendation system can use the unification matrix to produce the item predictions for users.
