Vietnamese tokenization, preprocess and models NLP

Genz Tokenize

Installation:

pip install genz-tokenize

Using for tokenize

    >>> from genz_tokenize import Tokenize
    # using vocab from lib
    >>> tokenize = Tokenize()
    >>> print(tokenize('sinh_viên công_nghệ', 'hello', max_len = 10, padding = True, truncation = True))
    # {'input_ids': [1, 770, 1444, 2, 2, 30469, 2, 0, 0, 0], 'attention_mask': [1, 1, 1, 1, 1, 1, 1, 0, 0, 0], 'sequence_id': [None, 0, 0, None, None, 1, None]}

    >>> print(tokenize.decode([1, 770, 2]))
    # <s> sinh_viên </s>

    # from your vocab
    >>> tokenize = Tokenize.fromFile('vocab.txt','bpe.codes')

Using bert tokenize inheritance from PreTrainedTokenizer Transformers

    >>> from genz_tokenize import TokenizeForBert
    # Using vocab from lib
    >>> tokenize = TokenizeForBert()
    >>> print(tokenize(['sinh_viên công_nghệ', 'hello'], max_length=5, padding='max_length',truncation=True))
    # {'input_ids': [[1, 770, 1444, 2, 0], [1, 30469, 2, 0, 0]], 'token_type_ids': [[0, 0, 0, 0, 0], [0, 0, 0, 0, 0]], 'attention_mask': [[1, 1, 1, 1, 0], [1, 1, 1, 0, 0]]}

    # Using your vocab
    >>> tokenize = TokenizeForBert.fromFile('vocab.txt','bpe.codes')

Embedding matrix from fasttext

    >>> from genz_tokenize import get_embedding_matrix
    >>> embedding_matrix = get_embedding_matrix()

Preprocessing data

    >>> from genz_tokenize.preprocess import remove_punctuations,  convert_unicode, remove_emoji, vncore_tokenize

Model

1. Seq2Seq with Bahdanau Attention
2. Transformer classification
3. Transformer
4. BERT

Trainer

    >>> from genz_tokenize.base_model.utils import Config
    >>> from genz_tokenize.base_model.models import Seq2Seq, Transformer, TransformerClassification
    >>> from genz_tokenize.base_model.training import TrainArgument, Trainer

    # initial model
    >>> model = Seq2Seq(config)
    >>> x = tf.zeros(shape=(10, config.maxlen))
    >>> y = tf.zeros(shape=(10, config.maxlen))
    # create dataset
    >>> BUFFER_SIZE = len(x)

    >>> dataset_train = dataset_train.shuffle(BUFFER_SIZE)
