                Training vector, where n_samples is the number of samples and
                n_features is the number of features.

            y : array-like, shape=(n_samples,) or (n_samples, n_output), optional (default=None)
                Target relative to X for classification or regression;
                None for unsupervised learning.

            groups : array-like, shape=(n_samples,), optional (default=None)
                Group labels for the samples used while splitting the dataset into
                train/test set.
