Abstract: In this talk, we discuss a novel user-based collaborative filtering (CF) algorithm with improved performance for recommendation systems. The statistical information set (SIS) of individual rating data is, for the first time, employed to analyze the user rating habit, thereby facilitating the performance improvement of the CF algorithm. On the basis of the SIS, a new yet comprehensive similarity measure (SM) is proposed to quantify the distance between two users with focus on both the users' preferences on items and their rating habits. Compared with the traditional SM, our proposed SM is more general with clearer application insights in complicated situations. The developed CF algorithm makes full use of the known information of a recommendation system, which merits high prediction accuracy and wide application potential. The developed CF algorithm is applied to a real-world disease (Friedreich's ataxia) assessment system, where both the effectiveness and the superiority of our proposed algorithm are demonstrated.
