Struct Nmf 

pub struct Nmf {
    pub w: Array2<f64>,
    pub h: Array2<f64>,
    pub reconstruction_err: f64,
    pub n_iter: usize,
}

Fitted NMF factors.

Fields

w: Array2<f64>

W — the sample-side factor (n × n_components).

h: Array2<f64>

H — the component-side factor (n_components × d).

reconstruction_err: f64

Final Frobenius reconstruction error ‖X − W·H‖_F.

n_iter: usize

Number of iterations run.

Implementations

impl Nmf

pub fn fit( x: ArrayView2<'_, f64>, n_components: usize, seed: u64, ) -> Result<Self>

Fit with defaults (max_iter = 200, tol = 1e-4).

pub fn fit_with( x: ArrayView2<'_, f64>, n_components: usize, max_iter: usize, tol: f64, seed: u64, ) -> Result<Self>

Full-configuration fit.
