    pub dim: usize,
    pub total_walk_steps: usize,
}

Computed Node2Vec embeddings.

Fields

embeddings: HashMap<String, Vec<f64>>

Map from node URI/label → embedding vector.

dim: usize

Implementations

impl Node2VecEmbeddings

pub fn get(&self, node: &str) -> Option<&[f64]>

Return the embedding for a specific node, if present.

pub fn cosine_similarity(&self, a: &str, b: &str) -> Option<f64>

Cosine similarity between two node embeddings.

Returns None if either node is missing or an embedding has zero norm.

pub fn top_k_similar(&self, query: &str, k: usize) -> Vec<(String, f64)>

Return the k most similar nodes to query by cosine similarity.
