Struct linfa_preprocessing::whitening::Whitener

pub struct Whitener { /* fields omitted */ }

Struct that can be fitted to the input data to obtain the related whitening matrix. Fitting returns a FittedWhitener struct that can be used to apply the whitening transformation to the input data.

Implementations

impl Whitener

pub fn pca() -> Self

Creates an instance of a Whitener that uses the PCA method

pub fn zca() -> Self

Creates an instance of a Whitener that uses the ZCA (Mahalanobis) method

pub fn cholesky() -> Self

Creates an instance of a Whitener that uses the cholesky decomposition of the inverse of the covariance matrix

pub fn method(self, method: WhiteningMethod) -> Self
