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

$1 - \frac{u \cdot v} {||u||_2 ||v||_2}.$

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.
