==Introduction==
A multi-way graph with K perspectives is a collection of K matrices <math>{X_1,X_2.....X_K}</math> 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.
