Struct PcaResult 

Source 
pub struct PcaResult {
    pub components: Tensor,
    pub eigenvalues: Vec<f32>,
    pub explained_variance_ratio: Vec<f32>,
}
Expand description

Result of a PCA decomposition via power iteration.

Fields§

§components: Tensor

Principal component directions, shape [k, n_features].

Each row is a unit-length direction in feature space, ordered by decreasing eigenvalue.

§eigenvalues: Vec<f32>

Eigenvalues of the kernel matrix, one per component.

§explained_variance_ratio: Vec<f32>

Fraction of total variance explained by each component.

Values sum to at most 1.0. The total variance is the trace of the (centered) kernel matrix.
