非负张量分解的快速算法
Fast algorithm to nonnegative tensor factorization
摘要
Abstract
Abstract: As the multi-linear extension of nonnegative matrix factorization, nonnegative tensor factorization has been success-fully applied in many fields including signal processing,computer vision, data mining and neuroscience. This paper proposed a fast algorithm to nonnegative tensor factorization. Firstly, regarded a lager tensor data as the discretization of multivariate con-tinuous function and obtained a corresponding smaller tensor data by sampling. Secondly, performed the nonnegative factoriza-tion on the small tensor and easily computed the corresponding reconstruction tensor. Then, employed for the above reconstruc-tion tensor, two-dimensional linear interpolation to reconstruct the original tensor. Finally,the experimental results show the ef-fectiveness of the proposed fast algorithm to nonnegative tensor factorization.关键词
