Struct SparsePCA 

pub struct SparsePCA {
    pub components: Array2<f64>,
    pub mean: Array1<f64>,
    pub n_components: usize,
    pub alpha: f64,
    pub n_iter: usize,
}

Fitted SparsePCA.

Fields

components: Array2<f64>

Sparse component loadings (k × d).

mean: Array1<f64>

Column mean subtracted at fit time.

n_components: usize

Kept rank.

alpha: f64

L1 penalty α used.

n_iter: usize

Convergence iterations run.

Implementations

impl SparsePCA

pub fn fit(x: ArrayView2<'_, f64>, n_components: usize) -> Result<Self>

Fit with defaults alpha = 1.0, max_iter = 100, tol = 1e-6.

pub fn fit_with( x: ArrayView2<'_, f64>, n_components: usize, alpha: f64, max_iter: usize, tol: f64, ) -> Result<Self>

Full-configuration fit.

pub fn transform(&self, x: ArrayView2<'_, f64>) -> Result<Array2<f64>>

Project new rows.
