Struct KernelPcaConfig 

pub struct KernelPcaConfig {
    pub n_components: usize,
    pub center: bool,
}

Configuration for KernelPCA.

Cheap to clone and Debug/PartialEq-comparable so it composes cleanly inside pipelines and hyperparameter sweeps.

Fields

n_components: usize

Number of principal components to retain.

center: bool

Whether to double-center the Gram matrix before eigendecomp.

Leaving this true (the default) is the standard Kernel PCA behaviour; setting it to false lets callers who have already centered their kernel (e.g. when chaining two kernel_pca instances) skip the redundant step.

Implementations

impl KernelPcaConfig

pub fn new(n_components: usize) -> Self

Build a configuration requesting n_components components with centering enabled.

pub fn with_center(self, center: bool) -> Self

Override the centering flag.

Trait Implementations

impl Clone for KernelPcaConfig

fn clone(&self) -> KernelPcaConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KernelPcaConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for KernelPcaConfig

fn eq(&self, other: &KernelPcaConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
