Loads the Reuters newswire classification dataset.

path where to cache the data (relative to ~/.keras/dataset).
num_words max number of words to include. Words are ranked by how often they occur (in the training set) and only the most frequent words are kept
skip_top skip the top N most frequently occurring words (which may not be informative).
maxlen truncate sequences after this length.
test_split Fraction of the dataset to be used as test data.
seed random seed for sample shuffling.
start_char The start of a sequence will be marked with this character. Set to 1 because 0 is usually the padding character.
oov_char words that were cut out because of the num_words or skip_top limit will be replaced with this character.
index_from index actual words with this index and higher.
**kwargs Used for backwards compatibility.

Tuple of Numpy arrays: (x_train, y_train), (x_test, y_test).

Note that the 'out of vocabulary' character is only used for words that were present in the training set but are not included because they're not making the num_words cut here. Words that were not seen in the training set but are in the test set have simply been skipped.
