Struct CosineSimilarity 

pub struct CosineSimilarity { /* private fields */ }

Cosine similarity kernel.

Computes cosine similarity: |N(u) ∩ N(v)| / sqrt(|N(u)| * |N(v)|) This is the normalized version of common neighbors.

Implementations

impl CosineSimilarity

pub fn new() -> Self

Create a new cosine similarity kernel.

pub fn compute_pair(graph: &CsrGraph, node_a: u64, node_b: u64) -> f64

Compute cosine similarity between two nodes.

pub fn compute_all_pairs( graph: &CsrGraph, min_similarity: f64, max_pairs: usize, ) -> Vec<SimilarityScore>

Compute cosine similarity for all pairs above a threshold.
