Motivation
This project seeks to extend the work we did previously on sentiment analysis using simple Feed-Foward Neural Networks (Found here: paper & repo). Instead, we wish to experiment with building a combined CNN-LSTM Neural Net model using Tensorflow to perform sentiment analysis on Twitter data.
Dependencies
sudo -H pip install -r requirements.txt
Run the Code
- On train.py change the variable MODEL_TO_RUN = {0 or 1}
- 0 = CNN-LSTM
- 1 = LSTM-CNN
- Feel free to change other variables (batch_size, filter_size, etc...)
- Run
python train.py(or, with proper permissions,./train.py
Code Structure
- lstm_cnn.py : Contains the LSTM_CNN Model class to be instantiated.
- cnn_lstm.py : Contains the CNN_LSTM Model class to be instantiated.
- train.py : Main runner for the code. It instantiates a model, trains it and validates it.
- batchgen.py : Contains a couple of functions needed to pre-process and tokenize the dataset.
