neighbor

The neighbor modules provide functionality for performing nearest neighbor search and pairwise distance calculations in those searches.

This submodule consists of the following modules:

• neighbor.knn_graph: Contains functions for setting up a nearest neighbor search index and constructing knn graphs.

• neighbor.search: Contains a helper function that wraps the default implementation of nearest neighbor searches.

• neighbor.metric: Contains functions for selecting distance metrics for nearest neighbor searches.
