Enum RBFKernel 

pub enum RBFKernel {
    Gaussian,
    Multiquadric,
    InverseMultiquadric,
    ThinPlateSpline,
    Linear,
    Cubic,
}

Available radial basis function kernels

Variants

Gaussian

Gaussian: φ(r) = exp(-ε²r²) Infinitely smooth but highly local

Multiquadric

Multiquadric: φ(r) = sqrt(1 + (εr)²) Moderately smooth and less local

InverseMultiquadric

Inverse Multiquadric: φ(r) = 1/sqrt(1 + (εr)²) Infinitely smooth with moderate locality

ThinPlateSpline

Thin Plate Spline: φ(r) = r² ln(r) Minimizes curvature, very smooth

Linear

Linear: φ(r) = r Simplest RBF, not smooth at data points

Cubic

Cubic: φ(r) = r³ Good compromise between smoothness and locality

Trait Implementations

impl Clone for RBFKernel

fn clone(&self) -> RBFKernel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RBFKernel

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

Formats the value using the given formatter.

impl PartialEq for RBFKernel

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