cupyx.scipy.spatial.distance.russellrao(u, v)

Compute the Russell-Rao distance between two 1-D arrays.

The Russell-Rao distance is defined as the proportion of elements in both u and v that are in the exact same position:

\[d(u, v) = \frac{1}{n} \sum_{k=0}^n u_i = v_i\]

where \(x = y\) is one if \(x\) is different from \(y\) and zero otherwise.

Parameters:

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

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

Returns:

The Hamming distance between vectors u and v.

Return type:

hamming (double)
