Fields

dim: usize

k: usize

mean: Vec<f32>

Column means.

components: Vec<f32>

[k, dim], row c the c-th component.

variances: Vec<f64>

Variance along each component (/ (L − 1)).

iterations: usize

Subspace iterations run (0: direct eigendecomposition).

Implementations

impl TopComponents

pub fn fit<S: RowSource>( client: &Client, src: &S, k: usize, opts: &TopComponentsOptions, ) -> Self

The leading k components of src (module docs).

Panics

If src has no rows or no features.

pub fn transform<S: RowSource>( &self, client: &Client, src: &S, batch_elements: usize, ) -> Vec<f32>

(x − μ) · Vᵀ of every row of src, [rows, k] on the host.

Panics

If src has another number of features.
