sklearn.datasets.fetch_rcv1()

data_home : string, optional

Specify another download and cache folder for the datasets. By default all scikit learn data is stored in ?~/scikit_learn_data? subfolders.

subset: string, ?train?, ?test?, or ?all?, default=?all? :

Select the dataset to load: ?train? for the training set (23149 samples), ?test? for the test set (781265 samples), ?all? for both, with the training samples first if shuffle is False. This follows the official LYRL2004 chronological split.

download_if_missing : boolean, default=True

If False, raise a IOError if the data is not locally available instead of trying to download the data from the source site.

random_state : int, RandomState instance or None, optional (default=None)

Random state for shuffling the dataset. If int, random_state is the seed used by the random number generator; If RandomState instance, random_state is the random number generator; If None, the random number generator is the RandomState instance used by np.random.

shuffle : bool, default=False

Whether to shuffle dataset.
