spamosaic.MNN.nn_approx

spamosaic.MNN.nn_approx(ds1, ds2, names1, names2, knn=50)[source]

Approximate nearest-neighbor search using HNSW (hnswlib).

Parameters:

ds1 (np.ndarray) – Query dataset of shape (N1, D).
ds2 (np.ndarray) – Reference dataset of shape (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 for each query.

Returns:

Set of matched (query_name, reference_name) pairs.

Return type:

set[tuple[str, str]]
