摘要: In general, algorithms for order-3 CANDECOMP/ PARAFAC (CP), also coined canonical polyadic decomposition (CPD), are easy to implement and can be extended higher order CPD. Unfortunately, the become computationally demanding, they often not applicable relatively large scale tensors. this paper, by exploiting uniqueness of CPD relation a tensor in Kruskal form its unfolded tensor, we propose fast approach deal with problem. Instead directly factorizing high data method decomposes an lower order, e.g., tensor. On basis estimated structured same dimension as is then generated, decomposed find final solution using addition, strategies unfold tensors suggested practically verified paper.
