        In the new space, each dimension is the cosine distance to the cluster
        centers.  Note that even if X is sparse, the array returned by
        `transform` will typically be dense.

        Parameters
        ----------
        X : {array-like, sparse matrix}, shape = [n_samples, n_features]
            New data to transform.

        Returns
        -------
        X_new : array, shape [n_samples, k]
            X transformed in the new space.
