Member Data Documentation

ef_construction

int knncolle_hnsw::HnswOptions::ef_construction = 200

Size of the dynamic list of nearest neighbors during index construction. This controls the trade-off between indexing time and accuracy and is equivalent to the ef_construct parameter in the underlying hnswlib library, see here for details.

ef_search

int knncolle_hnsw::HnswOptions::ef_search = 10

Size of the dynamic list of nearest neighbors during searching. This controls the trade-off between search speed and accuracy and is equivalent to the ef parameter in the underlying hnswlib library, see here for details.

num_links

int knncolle_hnsw::HnswOptions::num_links = 16

Number of bidirectional links for each node. This is equivalent to the M parameter in the underlying hnswlib library, see here for details.
