Struct CoOccurrenceIndex 

pub struct CoOccurrenceIndex { /* private fields */ }

Co-occurrence embeddings built from short random walks on the graph.

Implementations

impl CoOccurrenceIndex

pub fn build( graph: &Graph, walk_length: usize, walks_per_node: usize, window_size: usize, ) -> M1ndResult<Self>

Build co-occurrence embeddings from random walks. Replaces: semantic_v2.py CoOccurrenceEmbedder.build() FM-SEM-004: memory warning logged if node_count > 10_000.

pub fn cosine_similarity( a: &CoOccurrenceVector, b: &CoOccurrenceVector, ) -> FiniteF32

Cosine similarity between two sorted co-occurrence vectors. Uses merge-intersection on sorted vectors for O(D) instead of O(D^2).

pub fn query_top_k( &self, query_node: NodeId, top_k: usize, ) -> Vec<(NodeId, FiniteF32)>

Score a query node against all nodes. Returns top_k. Replaces: semantic_v2.py CoOccurrenceEmbedder.query()
