scipy.spatial.distance.cosine(u, v, w=None)[source]¶ Computes the Cosine distance between 1-D 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.
w : (N,) array_like, optional
The weights for each value in u and v. Default is None, which gives each value a weight of 1.0
Returns: cosine : double
The Cosine distance between vectors u and v.
