Tensor decomposition

In multilinear algebra, a tensor decomposition is any scheme for expressing a "data tensor" (M-way array) as a sequence of elementary operations acting on other, often simpler tensors.^[1]^[2]^[3] Many tensor decompositions generalize some matrix decompositions.^[4]

Tensors are generalizations of matrices to higher dimensions (or rather to higher orders, i.e. the higher number of dimensions) and can consequently be treated as multidimensional fields.^[1]^[5] The main tensor decompositions are:

Tensor rank decomposition;^[6]
Higher-order singular value decomposition;^[7]
Tucker decomposition;
matrix product states, and operators or tensor trains;
Online Tensor Decompositions^[8]^[9]^[10]
hierarchical Tucker decomposition;^[11]
block term decomposition^[12]^[13]^[11]^[14]

Notation

This section introduces basic notations and operations that are widely used in the field.

Introduction

A multi-way graph with K perspectives is a collection of K matrices ${X_{1},X_{2}.....X_{K}}$ with dimensions I × J (where I, J are the number of nodes). This collection of matrices is naturally represented as a tensor X of size I × J × K. In order to avoid overloading the term “dimension”, we call an I × J × K tensor a three “mode” tensor, where “modes” are the numbers of indices used to index the tensor.
