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.

Trait Implementations

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

type Object = Pca<f64>

source

fn fit(&self, dataset: &DatasetBase<ArrayBase<D, Ix2>, T>) -> Result<Pca<f64>>
