Struct KernelSelector 

pub struct KernelSelector {
    pub candidates: Vec<Box<dyn Kernel>>,
    pub config: KernelSelectionConfig,
}

Builder for running kernel selection over a fixed set of candidate kernels.

Examples

let candidates: Vec<Box<dyn Kernel>> = vec![Box::new(RBF::new(1.0)), Box::new(Linear::new(1.0, 1.0))];
let selector = KernelSelector::new(candidates).criterion(SelectionCriterion::Bic);
let result = selector.select(&X, &y).expect("selection should succeed with valid data");

Fields

candidates: Vec<Box<dyn Kernel>>

Candidate kernels to evaluate.

config: KernelSelectionConfig

Selection configuration.

Implementations

impl KernelSelector

pub fn new(candidates: Vec<Box<dyn Kernel>>) -> Self

Create a new selector over the given candidate kernels, using default configuration (BIC criterion).

pub fn config(self, config: KernelSelectionConfig) -> Self

Set the full configuration at once.

pub fn criterion(self, criterion: SelectionCriterion) -> Self

Set the selection criterion.

pub fn cv_folds(self, cv_folds: usize) -> Self

Set the number of cross-validation folds (used only for SelectionCriterion::Cv).

pub fn noise_variance(self, noise_variance: f64) -> Self

Set the initial observation noise variance.

pub fn random_state(self, random_state: Option<u64>) -> Self

Set the random state controlling the CV fold shuffle.

pub fn select( &self, X: &Array2<f64>, y: &Array1<f64>, ) -> SklResult<KernelSelectionResult>

Run selection against the given training data.
