DBSCAN error with cosine metric in python

Question

I was trying to use DBSCAN algorithm from scikit-learn library with cosine metric but was stuck with the error. The line of code is

db = DBSCAN(eps=1, min_s         


        

Answer 1

The indexes in sklearn (probably - this may change with new versions) cannot accelerate cosine.

Try algorithm='brute'.

For a list of metrics that your version of sklearn can accelerate, see the supported metrics of the ball tree:

from sklearn.neighbors.ball_tree import BallTree
print(BallTree.valid_metrics)
