Struct EditDistanceKernel 

pub struct EditDistanceKernel { /* private fields */ }

Edit distance kernel (exponential of negative edit distance)

K(s1, s2) = exp(-gamma * edit_distance(s1, s2))

Implementations

impl EditDistanceKernel

pub fn new(gamma: f64) -> Result<Self>

Create a new edit distance kernel

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

Compute similarity between two text strings
