scipy.spatial.distance.canberra¶
- scipy.spatial.distance.canberra(u, v)[source]¶
Computes the Canberra distance between two 1-D arrays.
The Canberra distance is defined as
d(u,v)=∑i|ui−vi||ui|+|vi|.Parameters: u : (N,) array_like
Input array.
v : (N,) array_like
Input array.
Returns: canberra : double
The Canberra distance between vectors u and v.
Notes
When u[i] and v[i] are 0 for given i, then the fraction 0/0 = 0 is used in the calculation.
