cupyx.scipy.spatial.distance.cosine(u, v)[source]#

Compute the Cosine distance between two 1-D arrays.

The Cosine distance is defined as

$d(u, v) = 1 - \frac{u \cdot v}{\|u\|_2 \|v\|_2}$

where $$x \cdot y$$ is the dot product.

Parameters
• u (array_like) – Input array of size (N,)

• v (array_like) – Input array of size (N,)

Returns

The Cosine distance between vectors u and v.

Return type

cosine (double)
