Quick Start Guide
=================

`Dataset Loading <http://gluon-nlp.mxnet.io/master/api/data.html>`__
-------------------------------------------------------------------------------------

Load the Wikitext-2 dataset, for example:

.. code:: python

>>> import gluonnlp as nlp
>>> train = nlp.data.WikiText2(segment='train')
>>> train[0][0:5]
['=', 'Valkyria', 'Chronicles', 'III', '=']

`Vocabulary Construction <http://gluon-nlp.mxnet.io/master/api/vocab.html>`__
---------------------------------------------------------------------------------

Build vocabulary based on the above dataset, for example:

.. code:: python

>>> vocab = nlp.Vocab(counter=nlp.data.Counter(train[0]))
>>> vocab
Vocab(size=33280, unk="<unk>", reserved="['<pad>', '<bos>', '<eos>']")

`Neural Models Building <http://gluon-nlp.mxnet.io/master/api/model.html>`__
-----------------------------------------------------------------------------------

From the models package, apply an Standard RNN langauge model to the
above dataset:

.. code:: python

>>> model = nlp.model.language_model.StandardRNN('lstm', len(vocab),
... 200, 200, 2, 0.5, True)
>>> model
StandardRNN(
(embedding): HybridSequential(
(0): Embedding(33280 -> 200, float32)
(1): Dropout(p = 0.5, axes=())
)
(encoder): LSTM(200 -> 200.0, TNC, num_layers=2, dropout=0.5)
(decoder): HybridSequential(
(0): Dense(200 -> 33280, linear)
)
)

`Word Embeddings Loading <http://gluon-nlp.mxnet.io/master/api/embedding.html>`__
---------------------------------------------------------------------------------

For example, load a GloVe word embedding, one of the state-of-the-art
English word embeddings:

.. code:: python

>>> glove = nlp.embedding.create('glove', source='glove.6B.50d')
# Obtain vectors for 'baby' in the GloVe word embedding
>>> type(glove['baby'])
<class 'mxnet.ndarray.ndarray.NDArray'>
>>> glove['baby'].shape
(50,)
