摘要

摘要低秩张量张量项之间存在线性关系。这些线性关系可以用多线性多项式表示，称为生成多项式。我们使用生成多项式来计算张量秩分解和低秩张量近似。我们证明了如果给定张量足够接近低秩张量，则给出了准最优低秩张量近似。

Low Rank Tensor Decompositions and Approximations

Abstract There exist linear relations among tensor entries of low rank tensors. These linear relations can be expressed by multi-linear polynomials, which are called generating polynomials. We use generating polynomials to compute tensor rank decompositions and low rank tensor approximations. We prove that this gives a quasi-optimal low rank tensor approximation if the given tensor is sufficiently close to a low rank one.

期刊介绍： Journal of the Operations Research Society of China is the flagship journal of the Operations Research Society of China. Its primary goal is to promote researches and applications of all aspects of operational research. This journal provides a forum for practioners, academics and researchers in operational research and related fields. It will reflect the rapid social and economic development of China and lead to new problems and challenges which require new operations research methodology and techniques. It will publish 4 issues of one volume per year, including invited reviews, regular papers, short communications, book reviews and so on.
