Struct petal_decomposition::PcaBuilder

pub struct PcaBuilder { /* private fields */ }

Builder for Pca.

Examples

use petal_decomposition::PcaBuilder;

let x = ndarray::arr2(&[[0_f64, 0_f64], [1_f64, 1_f64]]);
let mut pca = PcaBuilder::new(1).build();
pca.fit(&x);

Implementations

impl PcaBuilder

pub fn new(n_components: usize) -> Self

Sets the number of components for PCA.

pub fn centering(self, centering: bool) -> Self

Indicates whether or not to perform mean-centering on input data. It is enabled by default. If the inputs are already centered, set centering to false. Note Pca::mean() will return an Array1 of 0’s if centering is false.

pub fn build<A: Scalar>(self) -> Pca<A>

Creates an instance of Pca.
