Pincipal Component Analysis parameters

Implementations

source

impl PcaParams

source

pub fn whiten(self, apply: bool) -> Self

Apply whitening to the embedding vector

Whitening will scale the eigenvalues of the transformation such that the covariance will be unit diagonal for the original data.

source

impl<T, D: Data<Elem = f64>> Fit<ArrayBase<D, Dim<[usize ; 2]>>, T, ReductionError> for PcaParams

Fit a PCA model given a dataset

The Principal Component Analysis takes the records of a dataset and tries to find the best fit in a lower dimensional space such that the maximal variance is retained.

Parameters

dataset: A dataset with records in N dimensions

Returns

A fitted PCA model with origin and hyperplane
