Deep Learning for Multi-Label Text Classification
This repository is my research project, and it is also a study of TensorFlow, Deep Learning(Fasttext, CNN, LSTM, RCNN, 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 problem.
Requirements
- Python 3.6
- Tensorflow 1.8 +
- Numpy
- Gensim
Innovation
Data part
- Make the data support Chinese and English.(Which use
jieba
seems easy) - Can use your own pre-trained word vectors.(Which use
gensim
seems easy) - Add embedding visualization based on the tensorboard.
Model part
- Add the correct L2 loss calculation operation.
- Add gradients clip operation to prevent gradient explosion.
- Add learning rate decay with exponential decay.
- Add a new Highway Layer (Which is useful according to the model performance).
- Add Batch Normalization Layer.
Code part
- Can choose to train the model directly or restore the model from checkpoint in
train.py
. - Can predict the labels via threshold and topK in
train.py
andtest.py
. - Can calculate the evaluation metrics --- AUC & AUPRC.
- Add
test.py
, the model test code, it can show the predict value of each labels of the data in Testset when creating the final prediction file. - Add other useful data preprocess functions in
data_helpers.py
. - Use
logging
for helping recording the whole info (including parameters display, model training info, etc.). - Provide the ability to save the best n checkpoints in
checkmate.py
, whereas thetf.train.Saver
can only save the last n checkpoints.
Data
See data format in data
folder which including the data sample files.
Text Segment
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) by two ways:
- Modify your datasets into the same format of the sample.
- Modify the data preprocess code in
data_helpers.py
.
Anyway, it should depends on what your data and task are.
Pre-trained Word Vectors
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.
