Coupled Canonical Polyadic Decompositions and (Coupled) Decompositions in Multilinear Rank-$(L_r,n,L_r,n,1)$ Terms---Part I: Uniqueness
Coupled Canonical Polyadic Decompositions and (Coupled) Decompositions in Multilinear Rank-$(L_r,n,L_r,n,1)$ Terms---Part I: Uniqueness
Coupled tensor decompositions are becoming increasingly important in signal processing and data analysis. However, the uniqueness properties of coupled tensor decompositions have not yet been studied. In this paper, we first provide new uniqueness conditions for one factor matrix of the coupled canonical polyadic decomposition (CPD) of third-order tensors. Then, …
