Research on User Clustering Collaborative Filtering Algorithm

Lihua Tian, Liguo Han, Junhua Yue
2016 International Journal of Hybrid Information Technology  
So we first fill the missing ratings by SVD prediction, and then implement k-means clustering in the filled matix.  ...  For these issues, a SVD-based K-means clustering CF algorithm is proposed. Traditional clustering-based CF algorithms have low recommendation precision because of data sparsity.  ...  If data are too sparse, cluster-based collaborative filtering predicts very inaccurately.  ...
