Enum KernelType 

#[repr(i32)]
pub enum KernelType {
    Linear = 0,
    Polynomial = 1,
    Rbf = 2,
    Sigmoid = 3,
    Precomputed = 4,
}

Type of kernel function.

Matches the integer constants in the original LIBSVM (svm.h): LINEAR=0, POLY=1, RBF=2, SIGMOID=3, PRECOMPUTED=4.

Variants

Linear = 0

K(x,y) = x·y

Polynomial = 1

K(x,y) = (γ·x·y + coef0)^degree

Rbf = 2

K(x,y) = exp(-γ·‖x-y‖²)

Sigmoid = 3

K(x,y) = tanh(γ·x·y + coef0)

Precomputed = 4

Kernel values supplied as a precomputed matrix.

Trait Implementations

impl Clone for KernelType

fn clone(&self) -> KernelType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KernelType

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

Formats the value using the given formatter.

impl Hash for KernelType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for KernelType

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