(X, Y)[source]¶ Computes the paired cosine distances between X and Y
Read more in the User Guide.
Parameters: - X : array-like, shape (n_samples, n_features)
- Y : array-like, shape (n_samples, n_features)
Returns: - distances : ndarray, shape (n_samples, )
Notes
The cosine distance is equivalent to the half the squared euclidean distance if each sample is normalized to unit norm
