Struct SigmoidKernel

pub struct SigmoidKernel {
    pub gamma: Option<f64>,
    pub coef0: Option<f64>,
}

Sigmoid (hyperbolic tangent) kernel

Fields

gamma: Option<f64>

kernel coefficient

coef0: Option<f64>

independent term in kernel function

Implementations

impl SigmoidKernel

pub fn with_params(self, gamma: f64, coef0: f64) -> Self

set parameters for kernel

use smartcore::svm::SigmoidKernel;
let knl = SigmoidKernel::default().with_params(0.7, 1.0);

pub fn with_gamma(self, gamma: f64) -> Self

set gamma parameter for kernel

use smartcore::svm::SigmoidKernel;
let knl = SigmoidKernel::default().with_gamma(0.7);

Trait Implementations

impl Clone for SigmoidKernel

fn clone(&self) -> SigmoidKernel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SigmoidKernel

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

Formats the value using the given formatter.

impl Default for SigmoidKernel

fn default() -> Self

Returns the “default value” for a type.

impl Kernel for SigmoidKernel

fn apply(&self, x_i: &Vec<f64>, x_j: &Vec<f64>) -> Result<f64, Failed>

Apply kernel function to x_i and x_j

impl PartialEq for SigmoidKernel

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