Struct SpectralClustering 

pub struct SpectralClustering { /* private fields */ }

Output of a spectral clustering run.

Implementations

impl SpectralClustering

pub fn fit_affinity( affinity: &[f64], n: usize, config: &SpectralConfig, ) -> GraphResult<Self>

Cluster n points from an n×n affinity matrix (row-major, flat slice).

Errors

• GraphError::InvalidPlan for shape / config inconsistencies.

pub fn fit_data( data: &[f64], n: usize, dim: usize, config: &SpectralConfig, ) -> GraphResult<Self>

Cluster n data points from a [n × dim] row-major data matrix, using an RBF affinity: A[i,j] = exp(−γ ‖x_i − x_j‖²).

Errors

• GraphError::InvalidPlan for shape / config inconsistencies.

pub fn labels(&self) -> &[usize]

Cluster label for each point (length n, values in [0, n_clusters)).

pub fn eigenvalues(&self) -> &[f64]

Eigenvalues of the normalised affinity matrix M = D^{-1/2} A D^{-1/2} for the selected eigenvectors (descending order).

pub fn n_clusters(&self) -> usize

Number of clusters.
