-# Generative Adversarial Networks (GAN)
-
-This demo implements GAN training described in the original GAN paper (https://arxiv.org/abs/1406.2661) and DCGAN (https://arxiv.org/abs/1511.06434).
-
-The general training procedures are implemented in gan_trainer.py. The neural network configurations are specified in gan_conf.py (for synthetic data) and gan_conf_image.py (for image data).
-
-In order to run the model, first download the corresponding data by running the shell script in ./data.
-Then you can run the command below. The flag -d specifies the training data (cifar, mnist or uniform) and flag --useGpu specifies whether to use gpu for training (0 is cpu, 1 is gpu).
-
-$python gan_trainer.py -d cifar --use_gpu 1
-
-The generated images will be stored in ./cifar_samples/
-The corresponding models will be stored in ./cifar_params/

-This configuration is a demonstration of how to implement the stacked LSTM
-with residual connections, i.e. an LSTM layer takes the sum of the hidden states
-and inputs of the previous LSTM layer instead of only the hidden states.
-This architecture is from:
-Yonghui Wu, Mike Schuster, Zhifeng Chen, Quoc V. Le, Mohammad Norouzi,
-Wolfgang Macherey, Maxim Krikun, Yuan Cao, Qin Gao, Klaus Macherey,
-Jeff Klingner, Apurva Shah, Melvin Johnson, Xiaobing Liu, Lukasz Kaiser,
-Stephan Gouws, Yoshikiyo Kato, Taku Kudo, Hideto Kazawa, Keith Stevens,
-George Kurian, Nishant Patil, Wei Wang, Cliff Young, Jason Smith, Jason Riesa,
-Alex Rudnick, Oriol Vinyals, Greg Corrado, Macduff Hughes, Jeffrey Dean. 2016.
-Google's Neural Machine Translation System: Bridging the Gap between Human and
-Machine Translation. In arXiv https://arxiv.org/pdf/1609.08144v2.pdf
-Different from the architecture described in the paper, we use a stack single
-direction LSTM layers as the first layer instead of bi-directional LSTM. Also,
-since this is a demo code, to reduce computation time, we stacked 4 layers
-instead of 8 layers.

-# Sequence Tagging
-
-This demo is a sequence model for assigning tags to each token in a sentence. The task is described at CONLL2000 Text Chunking task.
-
-## Download data
-```bash
-cd demo/sequence_tagging
-./data/get_data.sh
-```
-
-## Train model
-```bash
-cd demo/sequence_tagging
-./train.sh
-```
-
-## Model description
-
-We provide two models. One is a linear CRF model (linear_crf.py) with is equivalent to the one at leon.bottou.org/projects/sgd. The second one is a stacked bidirectional RNN and CRF model (rnn_crf.py).

-#Variational Autoencoder (VAE)
-
-This demo implements VAE training described in the original paper (https://arxiv.org/abs/1312.6114).
-
-
-In order to run the model, first download the MNIST dataset by running the shell script in ./data.
-
-Then you can run the command below. The flag --useGpu specifies whether to use gpu for training (0 is cpu, 1 is gpu).
-
-$python vae_train.py [--use_gpu 1]
-
-The generated images will be stored in ./samples/
-The corresponding models will be stored in ./params/
