Struct SpectralEmbedding 

pub struct SpectralEmbedding { /* private fields */ }

Spectral Embedding (Laplacian Eigenmaps) configuration.

Holds hyperparameters for the spectral embedding algorithm. Call Fit::fit to compute the Laplacian eigenmap and obtain a FittedSpectralEmbedding.

Implementations

impl SpectralEmbedding

pub fn new(n_components: usize) -> Self

Create a new SpectralEmbedding with n_components dimensions.

The default affinity is RBF { gamma: 1.0 }.

pub fn with_affinity(self, affinity: Affinity) -> Self

Set the affinity function.

pub fn n_components(&self) -> usize

Return the configured number of components.

pub fn affinity(&self) -> Affinity

Return the configured affinity.

Trait Implementations

impl Clone for SpectralEmbedding

fn clone(&self) -> SpectralEmbedding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpectralEmbedding

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

Formats the value using the given formatter.

impl Fit<ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>, ()> for SpectralEmbedding

fn fit( &self, x: &Array2<f64>, _y: &(), ) -> Result<FittedSpectralEmbedding, FerroError>

Fit spectral embedding by building the affinity matrix, computing the normalized Laplacian, and extracting the bottom eigenvectors.

Errors

• FerroError::InvalidParameter if n_components is zero or too large.
• FerroError::InsufficientSamples if there are fewer than 2 samples.

type Fitted = FittedSpectralEmbedding

The fitted model type returned by fit.

type Error = FerroError

The error type returned by fit.
