Approximate nearest neighbor search using HNSW (hnswlib).

Parameters:

  • ds1 (np.ndarray) – Query dataset (N1, D).

  • ds2 (np.ndarray) – Reference dataset (N2, D).

  • names1 (list of str) – Identifiers for rows in ds1.

  • names2 (list of str) – Identifiers for rows in ds2.

  • knn (int, default=50) – Number of nearest neighbors to find.

Returns:
