scipy.spatial.distance.canberra(u, v)¶

Computes the Canberra distance between two n-vectors u and v, which is defined as

$\frac{\sum_i {|u_i-v_i|}} {\sum_i {|u_i|+|v_i|}}.$

Parameters :

u : ndarray

An $n$ -dimensional vector.

v : ndarray

An $n$ -dimensional vector.

Returns :

d : double

The Canberra distance between vectors u and v.
