scipy.spatial.distance.cosine¶
- scipy.spatial.distance.cosine(u, v)[source]¶
Computes the Cosine distance between 1-D arrays.
The Cosine distance between u and v, is defined as
1−u⋅v||u||2||v||2.where u⋅v is the dot product of u and v.
Parameters: u : (N,) array_like
Input array.
v : (N,) array_like
Input array.
Returns: cosine : double
The Cosine distance between vectors u and v.
