Matrix factorization plays a fundamental role in collaborative filtering. There are two basic disciplines among collaborative filtering approaches: neighborhood-based methods and latent factor models. Based on the neighbor-entity spatial relationships, neighborhood-based methods capture the local structure of the user-item rating matrix. Latent factor models capture the global structure of the matrix. Neither neighborhood-based methods nor latent factor models can capture both of them. The recently developed capsule network can capture the part-whole spatial relationships in the images. The basic matrix factorization model and its extensions are among the most successful latent factor models. Motivated by the need for capturing both the local structure and the global structure of the matrix, and inspired by the recently developed capsule network, we propose a new matrix factorization model called capsule matrix factorization, which attempts to capture the two structure of the matrix by propagating the neighbor-entity spatial relationships in the rating matrix into the latent factor vectors. Experimental results on real datasets demonstrate that the capsule matrix factorization model improves the basic matrix model in terms of recommendation accuracy greatly. |
