Recommender Systems Clustering Using Bayesian Non Negative Matrix Factorization

Recommender Systems Clustering Using Bayesian Non Negative Matrix Factorization

Recommender Systems present a high-level of sparsity in their ratings matrices. The collaborative filtering sparse data makes it difficult to: 1) compare elements using memory-based solutions; 2) obtain precise models using model-based solutions; 3) get accurate predictions; and 4) properly cluster...
