Struct AdamicAdarIndex 

pub struct AdamicAdarIndex { /* private fields */ }

Adamic-Adar index kernel.

Computes Adamic-Adar index: Σ 1/log(|N(z)|) for all z ∈ N(u) ∩ N(v) This weights common neighbors inversely by their degree.

Implementations

impl AdamicAdarIndex

pub fn new() -> Self

Create a new Adamic-Adar index kernel.

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

Compute Adamic-Adar index between two nodes.

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

Compute Adamic-Adar for all pairs, returning those above threshold.

pub fn top_k_pairs(graph: &CsrGraph, k: usize) -> Vec<SimilarityScore>

Find top-k most similar pairs for link prediction.
