三阶张量,就是order为3的张量。 为了方便自己区分,我将张量的在每个方向上的大小称为维度,例如:3*4*5。2、rankrank称为张量的秩。Rank-one Tensors:如果一个N阶张量可以表示成N个向量的外积,那么这个张量的秩为1。TensorRank:将张量分解成秩1张量,秩1张量的最小数称为张量的秩。

A rank 1 tensor is a tensor of the form v 1 ⊗ ⋯ ⊗ v k with v i ∈ V i and v i ≠ 0 for all i. The tensor T is said to be concise if there are not subspaces W i ⊆ V i , i = 1 , ⋯ , k with W i ≠ V i for at least one i and T ∈ W 1 ...
