int a[2][3] = {{1,2,3},{4,5,6}}; 我们就写成 a = Array((3,2),[1,2,3,4,5,6]) 先看单目运算。sum的输入是一个rank-n的数组,输出是rank-(n-1)的数组 sum of Array((3,), [1,2,3]) 1 + 2 + 3 = 6 sum of Array((3,2), [1,2,3,4,5,6]) 1 2 3 + + + 4
rank=1: [0,1,2] rank=2: [[0,1],[2,3]] rank=3: [[[0,1],[2,3]],[[4,5],[6,7]]] 什么是Shape shape是形状,他是指明每一层有多少个元素。比如[2,3,4]是指第一层2个元素,第二层3个元素,第三层4个元素,通过这个我们就可以知道这个张量一共有2 × 3 × 4=24 个元素。上面的r...

We construct a Harder-Narasimhan filtration for rank $2$ tensors, where there does not exist any such notion a priori, as coming from a GIT notion of maximal unstability. The filtration associated to the 1-parameter subgroup of Kempf giving the maximal way to destabilize, in the GIT sense,...

computation of the rank of the tensor. Tensor rank is not a straight-forward extension of matrix rank. A constructive proof based on an eigenvalue criterion is provided that shows when a 2×2×2 tensor over is rank-3 and when it is rank-2. The results are extended to show that n×n...

In Section 2, we provide some introduction about t-product for 3-order tensor and L2E method. In Section 3, we propose the new robust tensor recovery via L2E including its estimation algorithm. Some convergence properties of our method are given in Section 4. Some experimental results are ...
