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。 Tensor Rank:将张量分解成秩1张量,秩1张量的最小数称为张量的秩。 张量分解 (alternating least squares)框架),并且在实际应用中,我们需要用到的张量分解通常是用来解决稀疏张量的填补问题。由于Tucker分解为张量分解提供了一个...
Something went wrong when broadcasting. My idea was to elevate the rank 0 tensor to a rank 1 tensor (of length one), and then broadcast in the single dimension to replicate the maximum as many times as I need to be able to subtract it from something else. What is...

这是比较特殊的情况, Rank, Shape 都不知道 因为TensorFlow 是先定义, 后执行, 有些信息在运行 Computation Graph 的时候再运算, 所以会出现上述在定义时, 未知的情况。 参考文档: [1]Understanding Tensorflow's tensors shape: static and dynamic, Paolo Galeone, 01/28/2018...
We show that sums of rank one tensors (or separable functions) representing the so-called Candecomp/Parafac or CP-decomposition is used effectively to solve the chemical master equations as in many cases the effective tensor rank of the probability distribution only grows slowly with time. Both ...
先来看看传统的low-rank分解,传统的low-rank分解文中举的例子是CP分解(将一个多维张量分解为几个rank-one tensor的和)还有Tucker分解(将一个多维张量分解为一个核张量和每一维的乘积)具体的解释可以参考Tensor Decompositions and Applications。这两种分解的共同点就是将一个已经学习完的weight矩阵,比如W∈Rm×n,要...

We derive several perturbative results that are relevant to the well-posedness of recovering rank-one structure from approximately-rank-one symmetric tensors. We also specialize the analysis of the shifted symmetric higher-order power method, an algorithm for computing symmetric tensor eigenvectors, to...
