Enum Affinity 

pub enum Affinity {
    RBF {
        gamma: f64,
    },
    NearestNeighbors {
        n_neighbors: usize,
    },
}

The affinity function for building the weight matrix.

Variants

RBF

RBF (Gaussian) kernel: W_ij = exp(-gamma * ||x_i - x_j||^2).

Fields

gamma: f64

Kernel bandwidth parameter.

NearestNeighbors

k-nearest-neighbors: W_ij = 1 if j is among the k nearest neighbors of i (or vice versa), 0 otherwise.

Fields

n_neighbors: usize

Number of neighbors.

Trait Implementations

impl Clone for Affinity

fn clone(&self) -> Affinity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Affinity

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

Formats the value using the given formatter.

impl PartialEq for Affinity

fn eq(&self, other: &Affinity) -> 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.

impl Copy for Affinity

impl StructuralPartialEq for Affinity
