Note: I don't provide personal support for custom changes in the code. Only for the release. For people just starting, I recommend Treehouse for online-learning.

Based on the Interspeech '13 paper:

Grégoire Mesnil, Xiaodong He, Li Deng and Yoshua Bengio - Investigation of Recurrent Neural Network Architectures and Learning Methods for Spoken Language Understanding

We also have a follow-up IEEE paper:

Grégoire Mesnil, Yann Dauphin, Kaisheng Yao, Yoshua Bengio, Li Deng, Dilek Hakkani-Tur, Xiaodong He, Larry Heck, Gokhan Tur, Dong Yu and Geoffrey Zweig - Using Recurrent Neural Networks for Slot Filling in Spoken Language Understanding

This code allows to get state-of-the-art results and a significant improvement (+1% in F1-score) with respect to the results presented in the paper.

In order to reproduce the results, make sure Theano is installed and the repository is in your PYTHONPATH, e.g run the command export PYTHONPATH=/path/where/is13/is:$PYTHONPATH. Then, run the following commands:

git clone git@github.com:mesnilgr/is13.git python is13/examples/elman-forward.py 

For running the Jordan architecture:

python is13/examples/jordan-forward.py 

Download ATIS Dataset here! split 0 split 1 split 2 split 3 split 4

import cPickle train, test, dicts = cPickle.load(open("atis.pkl")) 

dicts is a python dictionnary that contains the mapping from the labels, the name entities (if existing) and the words to indexes used in train and test lists. Refer to this tutorial for more details.

Running the following command can give you an idea of how the data has been preprocessed:
