Privacy Preserving Collaborative Fuzzy Co-clustering of Three-Mode Cooccurrence Data
説明
Co-cluster structure analysis with three-mode cooccurrence information is a potential approach in summarizing multi-source relational data in such tasks as user-product purchase history analysis. This paper proposes a privacy preserving framework for jointly performing three-mode fuzzy co-clustering under collaboration among two organizations, which independently store object-item cooccurrence information and item-ingredient cooccurrence information, respectively. Even when they cannot mutually share elements of the cooccurrence matrices, the intrinsic co-cluster structures are revealed without publishing each elements of relational data but sharing only the structural information.
