scipy.spatial.distance.
cosine
(u, v)[source]¶ Computes the Cosine distance between 1D arrays.
The Cosine distance between u and v, is defined as
\[1  \frac{u \cdot v} {u_2 v_2}.\]where \(u \cdot v\) 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.
