Struct ValueSimilarity 

pub struct ValueSimilarity { /* private fields */ }

Value similarity kernel.

Compares probability distributions using statistical distance metrics:

• Jensen-Shannon Divergence (JSD)
• Wasserstein Distance (Earth Mover’s)

Implementations

impl ValueSimilarity

pub fn new() -> Self

Create a new value similarity kernel.

pub fn jensen_shannon_divergence(p: &[f64], q: &[f64]) -> f64

Compute Jensen-Shannon Divergence between two distributions.

JSD(P||Q) = 0.5 * KL(P||M) + 0.5 * KL(Q||M) where M = 0.5 * (P + Q)

pub fn jsd_similarity(p: &[f64], q: &[f64]) -> f64

Compute similarity from JSD (normalized to [0, 1]).

pub fn wasserstein_distance(p: &[f64], q: &[f64]) -> f64

Compute Wasserstein-1 distance (Earth Mover’s Distance) for 1D distributions.

For 1D sorted bins: W1(P,Q) = Σ|CDF_P[i] - CDF_Q[i]|

pub fn wasserstein_similarity(p: &[f64], q: &[f64]) -> f64

Compute similarity from Wasserstein distance.

pub fn compute_all_pairs_jsd( distributions: &ValueDistribution, min_similarity: f64, max_pairs: usize, ) -> Vec<ValueSimilarityResult>

Compute pairwise similarities using JSD.

pub fn compute_all_pairs_wasserstein( distributions: &ValueDistribution, min_similarity: f64, max_pairs: usize, ) -> Vec<ValueSimilarityResult>

Compute pairwise similarities using Wasserstein distance.

pub fn find_similar_nodes( distributions: &ValueDistribution, target_node: usize, min_similarity: f64, top_k: usize, ) -> Vec<ValueSimilarityResult>

Find nodes with similar value distributions.
