5.6.1.13. 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.
