Struct TernaryRBFSimilarity 

pub struct TernaryRBFSimilarity {
    pub gamma: f64,
}

RBF-like similarity measures for ternary data.

Fields

gamma: f64

Implementations

impl TernaryRBFSimilarity

pub fn new(gamma: f64) -> Self

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

Compute similarity between two ternary sequences.

pub fn hamming_distance(&self, a: &[Ternary], b: &[Ternary]) -> usize

Hamming distance between ternary sequences.

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

Weighted Hamming: opposite signs cost more than one being zero.

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

Similarity matrix for a set of sequences.

pub fn knn( &self, query: &[Ternary], data: &[Vec<Ternary>], k: usize, ) -> Vec<(usize, f64)>

Find k nearest neighbors.
