# Deep Learning for Multi-Label Text Classification [](https://www.python.org/downloads/) [](https://travis-ci.org/RandolphVI/Multi-Label-Text-Classification) [](https://www.codacy.com/app/chinawolfman/Multi-Label-Text-Classification?utm_source=github.com&utm_medium=referral&utm_content=RandolphVI/Multi-Label-Text-Classification&utm_campaign=Badge_Grade) [](https://www.apache.org/licenses/LICENSE-2.0) [](https://github.com/RandolphVI/Multi-Label-Text-Classification/issues) This repository is my research project, and it is also a study of TensorFlow, Deep Learning (Fasttext, CNN, LSTM, etc.). The main objective of the project is to solve the multi-label text classification problem based on Deep Neural Networks. Thus, the format of the data label is like [0, 1, 0, ..., 1, 1] according to the characteristics of such a problem. ## Requirements - Python 3.6 - Tensorflow 1.15.0 - Tensorboard 1.15.0 - Sklearn 0.19.1 - Numpy 1.16.2 - Gensim 3.8.3 - Tqdm 4.49.0 ## Project The project structure is below: ```text . ├── Model │   ├── test_model.py │   ├── text_model.py │   └── train_model.py ├── data │   ├── word2vec_100.model.* [Need Download] │   ├── Test_sample.json │   ├── Train_sample.json │   └── Validation_sample.json └── utils │   ├── checkmate.py │   ├── data_helpers.py │   └── param_parser.py ├── LICENSE ├── README.md └── requirements.txt ``` ## Innovation ### Data part 1. Make the data support **Chinese** and English (Can use `jieba` or `nltk` ). 2. Can use **your pre-trained word vectors** (Can use `gensim`). 3. Add embedding visualization based on the **tensorboard** (Need to create `metadata.tsv` first). ### Model part 1. Add the correct **L2 loss** calculation operation. 2. Add **gradients clip** operation to prevent gradient explosion. 3. Add **learning rate decay** with exponential decay. 4. Add a new **Highway Layer** (Which is useful according to the model performance). 5. Add **Batch Normalization Layer**. ### Code part 1. Can choose to **train** the model directly or **restore** the model from the checkpoint in `train.py`. 2. Can predict the labels via **threshold** and **top-K** in `train.py` and `test.py`. 3. Can calculate the evaluation metrics --- **AUC** & **AUPRC**. 4. Can create the prediction file which including the predicted values and predicted labels of the Testset data in `test.py`. 5. Add other useful data preprocess functions in `data_helpers.py`. 6. Use `logging` for helping to record the whole info (including **parameters display**, **model training info**, etc.). 7. Provide the ability to save the best n checkpoints in `checkmate.py`, whereas the `tf.train.Saver` can only save the last n checkpoints. ## Data See data format in `/data` folder which including the data sample files. For example: ```json {"testid": "3935745", "features_content": ["pore", "water", "pressure", "metering", "device", "incorporating", "pressure", "meter", "force", "meter", "influenced", "pressure", "meter", "device", "includes", "power", "member", "arranged", "control", "pressure", "exerted", "pressure", "meter", "force", "meter", "applying", "overriding", "force", "pressure", "meter", "stop", "influence", "force", "meter", "removing", "overriding", "force", "pressure", "meter", "influence", "force", "meter", "resumed"], "labels_index": [526, 534, 411], "labels_num": 3} ``` - **"testid"**: just the id. - **"features_content"**: the word segment (after removing the stopwords) - **"labels_index"**: The label index of the data records. - **"labels_num"**: The number of labels. ### Text Segment 1. You can use `nltk` package if you are going to deal with the English text data. 2. You can use `jieba` package if you are going to deal with the Chinese text data. ### Data Format This repository can be used in other datasets (text classification) in two ways: 1. Modify your datasets into the same format of [the sample](https://github.com/RandolphVI/Multi-Label-Text-Classification/blob/master/data). 2. Modify the data preprocessing code in `data_helpers.py`. Anyway, it should depend on what your data and task are. **🤔Before you open the new issue about the data format, please check the `data_sample.json` and read the other open issues first, because someone maybe ask me the same question already.

Make sure they are unzipped and under the `/data` folder.** You can pre-training your word vectors (based on your corpus) in many ways: - Use `gensim` package to pre-train data. - Use `glove` tools to pre-train data. - Even can use a **fasttext** network to pre-train data. ## Usage See [Usage](https://github.com/RandolphVI/Multi-Label-Text-Classification/blob/master/Usage.md). ## Network Structure ### FastText  References: - [Bag of Tricks for Efficient Text Classification](https://arxiv.org/pdf/1607.01759.pdf) --- ### TextANN  References: - **Personal ideas 🙃** --- ### TextCNN  References: - [Convolutional Neural Networks for Sentence Classification](http://arxiv.org/abs/1408.5882) - [A Sensitivity Analysis of (and Practitioners' Guide to) Convolutional Neural Networks for Sentence Classification](http://arxiv.org/abs/1510.03820) --- ### TextRNN **Warning: Model can use but not finished yet 🤪!**  #### TODO 1.
