The Not-so-Magic Magic Barrier of Recommender Systems

Alejandro Bellogin, Alan Said. 2015, "The Not-so-Magic Magic Barrier of Recommender Systems". Tiny Transactions on Computer Science.


Recommender Systems need to deal with different types of users who represent their preferences in various ways. This difference in user behaviour has a deep impact on the accuracy of the recommendations received by the users, depending, mostly, on the quantity and the quality of the information the system knows about the user. Specifically, the inconsistencies of the user impose a lower bound on the error the system may achieve when predicting ratings for that particular user [3].
