Struct linfa_preprocessing::whitening::Whitener

pub struct Whitener { /* private fields */ }

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

Trait Implementations

impl Clone for Whitener

fn clone(&self) -> Whitener

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Whitener

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<F: Float, D: Data<Elem = F>, T: AsTargets> Fit<ArrayBase<D, Dim<[usize; 2]>>, T, PreprocessingError> for Whitener

type Object = FittedWhitener<F>

fn fit(&self, x: &DatasetBase<ArrayBase<D, Ix2>, T>) -> Result<Self::Object>

impl PartialEq for Whitener

fn eq(&self, other: &Whitener) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
