Struct SubsequenceKernel 

pub struct SubsequenceKernel { /* private fields */ }

Subsequence string kernel

Measures similarity by counting common non-contiguous subsequences.

Implementations

impl SubsequenceKernel

pub fn new(config: SubsequenceKernelConfig) -> Self

Create a new subsequence kernel

pub fn compute_strings(&self, text1: &str, text2: &str) -> Result<f64>

Compute similarity between two text strings

impl Kernel for SubsequenceKernel

fn compute(&self, _x: &[f64], _y: &[f64]) -> Result<f64>

Compute kernel value between two inputs.

fn name(&self) -> &str

Get kernel name for identification.

fn compute_matrix(&self, inputs: &[Vec<f64>]) -> Result<Vec<Vec<f64>>>
