Trait Implementations

impl Clone for FittedKernelPca

fn clone(&self) -> FittedKernelPca

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FittedKernelPca

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FittedKernelPca

fn deserialize<__D>( __deserializer: __D, ) -> Result<FittedKernelPca, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl InverseTransform<f64> for FittedKernelPca

fn inverse_transform( &self, t: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>, ) -> Result<ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>, RustMlError>

Approximate pre-image: maps a low-dim projection back to a reconstruction in the original feature space.

Uses the linear approximation X̂ = T · diag(√λ) · αᵀ · X_train, which is exact for the linear kernel and a useful approximation for RBF / polynomial. Mirrors sklearn’s KernelPCA(fit_inverse_transform=False) fallback (sklearn’s full pre-image solver is iterative and not yet implemented here).

impl Serialize for FittedKernelPca

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Transform<f64> for FittedKernelPca

fn transform( &self, x: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>, ) -> Result<ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>, RustMlError>
