Struct TernaryKernel 

pub struct TernaryKernel {
    pub sigma: f64,
}

Kernel functions for ternary data.

Fields

sigma: f64

Implementations

impl TernaryKernel

pub fn new(sigma: f64) -> Self

pub fn rbf(&self, a: &[Ternary], b: &[Ternary]) -> f64

RBF-like kernel for ternary vectors.

pub fn matching(&self, a: &[Ternary], b: &[Ternary]) -> f64

Ternary matching kernel: counts matching positions.

pub fn agreement(&self, a: &[Ternary], b: &[Ternary]) -> f64

Ternary agreement kernel: +1 for same, -1 for opposite, 0 otherwise.

pub fn polynomial( &self, a: &[Ternary], b: &[Ternary], degree: i32, offset: f64, ) -> f64

Polynomial kernel for ternary vectors.

pub fn kernel_matrix( &self, data: &[Vec<Ternary>], kernel_type: KernelType, ) -> Vec<Vec<f64>>

Compute full kernel matrix for a set of ternary vectors.
