How to use

EDA: Easy Data Augmentation Techniques for Boosting Performance on Text Classification Tasks

Command

python -m aug_ja.eda.run --input input.tsv --output data_augmentor.tsv

The format of input.tsv is as follows:

1	この映画はとてもおもしろい
0	つまらない映画だった

In Python

from aug_ja.eda import EasyDataAugmentor
augmentor = EasyDataAugmentor(alpha_sr=0.1, alpha_ri=0.1, alpha_rs=0.1, p_rd=0.1, num_aug=4)
text = "日本語でデータ拡張を行う"
aug_texts = augmentor.augments(text)
print(aug_texts)
# ['日本語でを拡張データ行う', '日本語でデータ押広げるを行う', '日本語でデータ拡張を行う', '日本語で智見拡張を行う', '日本語でデータ拡張を行う']

An Analysis of Simple Data Augmentation for Named Entity Recognition

Command

python -m aug_ja.ner_sda.run --input input.tsv --output data_augmentor.tsv

The format of input.tsv is as follows:

私	O
は	O
田中	B-PER
と	O
いい	O
ます	O

In Python

from daaja.ner_sda import SimpleDataAugmentationforNER
tokens_list = [
    ["私", "は", "田中", "と", "いい", "ます"],
    ["筑波", "大学", "に", "所属", "して", "ます"],
    ["今日", "から", "筑波", "大学", "に", "通う"],
    ["茨城", "大学"],
]
labels_list = [
    ["O", "O", "B-PER", "O", "O", "O"],
    ["B-ORG", "I-ORG", "O", "O", "O", "O"],
    ["B-DATE", "O", "B-ORG", "I-ORG", "O", "O"],
    ["B-ORG", "I-ORG"],
]
augmentor = SimpleDataAugmentationforNER(tokens_list=tokens_list, labels_list=labels_list,
                                            p_power=1, p_lwtr=1, p_mr=1, p_sis=1, p_sr=1, num_aug=4)
tokens = ["吉田", "さん", "は", "株式", "会社", "A", "に", "出張", "予定", "だ"]
labels = ["B-PER", "O", "O", "B-ORG", "I-ORG", "I-ORG", "O", "O", "O", "O"]
augmented_tokens_list, augmented_labels_list = augmentor.augments(tokens, labels)
print(augmented_tokens_list)
# [['吉田', 'さん', 'は', '株式', '会社', 'A', 'に', '出張', '志す', 'だ'],

  • too many progress bars

    too many progress bars

    When I use EasyDataAugmentor in the train process, there are too many progress bars in the console.

    So, can you make this line 19 tqdm selectable on-off when we define EasyDataAugmentor? https://github.com/kajyuuen/daaja/blob/12835943868d43f5c248cf1ea87ab60f67a6e03d/daaja/flows/sequential_flow.py#L19

  • is it possible to use on GPU device?

    is it possible to use on GPU device?

    Hi!

    thank you for the great library. when I train with this augmentation, this takes so much more time than forward and backward process.

    therefore, can we possibly use this augmentation on GPU to save time?

    thank you

  • Bump joblib from 1.1.0 to 1.2.0

    Bump joblib from 1.1.0 to 1.2.0

    Bumps joblib from 1.1.0 to 1.2.0.

    Changelog

    Sourced from joblib's changelog.

    Release 1.2.0

    • Fix a security issue where eval(pre_dispatch) could potentially run arbitrary code. Now only basic numerics are supported. joblib/joblib#1327

    • Make sure that joblib works even when multiprocessing is not available, for instance with Pyodide joblib/joblib#1256

    • Avoid unnecessary warnings when workers and main process delete the temporary memmap folder contents concurrently. joblib/joblib#1263

    • Fix memory alignment bug for pickles containing numpy arrays. This is especially important when loading the pickle with mmap_mode != None as the resulting numpy.memmap object would not be able to correct the misalignment without performing a memory copy. This bug would cause invalid computation and segmentation faults with native code that would directly access the underlying data buffer of a numpy array, for instance C/C++/Cython code compiled with older GCC versions or some old OpenBLAS written in platform specific assembly. joblib/joblib#1254

    • Vendor cloudpickle 2.2.0 which adds support for PyPy 3.8+.

    • Vendor loky 3.3.0 which fixes several bugs including:

      • robustly forcibly terminating worker processes in case of a crash (joblib/joblib#1269);

      • avoiding leaking worker processes in case of nested loky parallel calls;

      • reliability spawn the correct number of reusable workers.

    Release 1.1.1

    • Fix a security issue where eval(pre_dispatch) could potentially run arbitrary code. Now only basic numerics are supported. joblib/joblib#1327
