WebApr 25, 2024 · 1 Answer. Let x by some vector with some covariance matrix Σ x = E [ ( x − μ x) ( x − μ x) T]. Next, recall the following theorem of random variable transformations: If A is some matrix, then y = A x ⇒ Σ y = A Σ x A T. Okay, so let's say you found some A so that A = Σ x − 0.5. Then, where I is the identity matrix. Web本文章探讨去相关与白化（decorrelation and whitening） 通常，数据集的各个attributes是存在一定相关性的，这就意味着存在冗余信息。 其实维度约减也是去冗余的一个过程。
