I guess I got it now! This behavior (see below) is indeed a bit strange:
from sklearn.neighbors import NearestNeighbors
import numpy as np
X = np.array([[1.0, 0.0, 1.0, 1.0], [0.0, 0.0, 1.0, 0.0], [1.0, 1.0, 1.0, 1.0]])
def tan(x, y):
print(y)
return 1
nbrs = NearestNeighbors(n_neighbors=1, algorithm='ball_tree', metric=tan).fit(X)
distances, indices = nbrs.kneighbors(X)
[ 0.51786272 0.53042315 0.87815766 0.90239616 0.34253599 0.98631925
0.29768794 0.36593595 0.28956526 0.24720931]
[ 1. 0. 1. 1.]
[ 0. 0. 1. 0.]
[ 1. 1. 1. 1.]
[ 0.66666667 0.33333333 1. 0.66666667]
[ 1. 0. 1. 1.]
[ 0. 0. 1. 0.]
[ 1. 1. 1. 1.]
[ 0.66666667 0.33333333 1. 0.66666667]
[ 1. 0. 1. 1.]
[ 0. 0. 1. 0.]
[ 1. 1. 1. 1.]

[ 1. 1. 1. 1.]
It seems to be due to the partitioning via the ball tree algorithm; I am not
sure if this is intended. It would be nice to get some feedback on this ...
Switching to "brute" seems to return the expected results:
from sklearn.neighbors import NearestNeighbors
import numpy as np
X = np.array([[1.0, 0.0, 1.0, 1.0], [0.0, 0.0, 1.0, 0.0], [1.0, 1.0, 1.0, 1.0]])
def tan(x, y):
print(y)
return 1
nbrs = NearestNeighbors(n_neighbors=1, algorithm='brute', metric=tan).fit(X)
distances, indices = nbrs.kneighbors(X)
[ 0. 0. 1. 0.]
[ 1. 1. 1. 1.]
[ 1. 1. 1. 1.]
[ 1. 0. 1. 1.]
[ 0. 0. 1. 0.]
[ 1. 1. 1. 1.]
