【彻底搞懂】矩阵奇异值分解(SVD) - 知乎专栏
SVD 定义. 矩阵的奇异值分解是 酉等价型 的分解: A\in C^{m\times n} , \exists 酉矩阵 U\in C^{m\times m}, V\in C^{n\times n}, 使得 A=U\Sigma V^{H} , ( 其中H表示复共轭转置, U^{H}U=UU^{H} =I) 至于为什么要这样分解?如何降维 ?----看文章后的案例,不懂顺网线打我 奇 …

【Tensor Computation for Data Analysis】T-SVD(Tensor
Dec 19, 2024 · T-SVD 是基于 t-product 的分解,可以将张量分解为三个部分:正交张量、对角张量和另一个正交张量。 它在信号处理、图像修复、视频分析等多维数据处理中非常有用。 1. 准备:张量和 T-SVD 的分解目标. A ∈ R n 1 × n 2 × n 3 \mathcal {A} \in \mathbb {R}^ {n_1 \times n_2 \times n_3} A ∈ Rn1×n2×n3 是一个三维张量。 T-SVD 的目标是将张量分解为: A = U ∗ S ∗ V ⊤ , \mathcal {A} = \mathcal {U} * \mathcal {S} * \mathcal {V}^\top, A = U ∗S ∗V ⊤, 其中:
