What is it?
This is the source code of my submission for the Kaggle competition ["Bag of Words Meets Bags of Popcorn"] (https://www.kaggle.com/c/word2vec-nlp-tutorial). The leader board score is 0.9766.
The model is an ensemble of NBSVM, Paragraph Vector and Gated Recurrent Neural Network. It is based on the code from the paper ["Ensemble of Generative and Discriminative Techniques for Sentiment Analysis of Movie Reviews"] (http://arxiv.org/abs/1412.5335) by Grégoire Mesnil and others.
How to run
-
Data should be put into the directory data.
-
The code requires numpy, pandas, Theano and passage which can be installed by running:
sudo pip install -r requirements.txt
- After that, run the following command to generate the submission file "ensemble-submission.csv":
chmod +x run.sh && time ./run.sh
- The code was tested on Ubuntu 14.04. It took about 1h16' on an i7 quad-core with a GTX Titan. The submission should give the score of ~0.976 on the leader board (it can be slightly different due to data shuffling during training).
