However, the current implementation is far from practical because of its common but ineffective network implementation and unconsidered potential conflicts in the GAN training procedure. In this paper, we propose an improved approach to realize a better Out-of-Domain texts generation, where we modify the Autoencoder for faster learning of context data, and also regularize the output to decrease the difficulty of GAN imitation afterwards. For GAN, we utilize different activation scheme and a more moderate training signal to solve the training conflicts.
