Struct PcaResult 

Source 
pub struct PcaResult {
    pub components: Vec<Vec<f64>>,
    pub explained_variance: Vec<f64>,
    pub explained_variance_ratio: Vec<f64>,
    pub reconstruction_error: f64,
}
Expand description

Outcome of a PCA fit.

Fields§

§components: Vec<Vec<f64>>

The top k principal components, one length-dim unit vector per row, in descending order of explained variance.

§explained_variance: Vec<f64>

Variance explained by each returned component (the leading eigenvalues of the covariance matrix).

§explained_variance_ratio: Vec<f64>

Each component’s explained variance as a fraction of the total variance across all features.

§reconstruction_error: f64

Mean squared error of reconstructing the input from the k components.
