This is a tensorflow implementation of Adversarial Ranking for Language Generation by Kevin Lin^*, Dianqi Li^*, Xiaodong He, Zhengyou Zhang, Ming-Ting Sun, NIPS 2017.

The code is based on python2.7 and tensorflow 1.2 version. The code is developed and tested using one NVIDIA M40 GPU.

python main.py

• For a fair comparison, we used same LSTMs units, pre-train and test configurations in SeqGan. If you use tf.contrib.rnn.LSTMCell instead of their LSTMs implementation, you will obtain different training results.
• save/target_params.pkl is the parameter for the oracle model from SeqGan. log folder stores the log of your model training.
• Ideally, you will receive a nll loss between 8.00-8.50. However, adversarial training sometimes depends on the quality of pre-train model.
• More evaluation metrics for adversarial text generation can be refered to: paper and repo.
