select_orthogonal_anchors(
    embeddings,
    k,
    seed_indices=None,
    candidate_indices=None,
    use_bridges=True,
    global_num_bits=12,

)

Select k maximally spread anchors using greedy farthest-point sampling.

Achieves ~87% of full-bridge recall with ~22% of anchors by eliminating redundancy in anchor placement.

Parameters

Name	Type	Description	Default
embeddings	np.ndarray	Normalized embeddings (n_points, dim)	required
k	int	Number of anchors to select	required
seed_indices	Optional[np.ndarray]	Initial seed points (default: super connectors)	None
candidate_indices	Optional[np.ndarray]	Pool to select from (default: bridges or all points)	None
use_bridges	bool	If True and candidate_indices is None, use bridge points	True
global_num_bits	int	LSH bits for bridge detection	12
seed	int	Random seed	42

Returns

Name	Type	Description
	OrthogonalAnchorResult	OrthogonalAnchorResult with selected indices
