Abstract: This paper proposes a generative model that implements cooperative adversarial learning via closed-loop transcription. In the generative model training, the encoder and decoder are trained simultaneously, and not only the adversarial process but also a cooperative process is included. In the adversarial process, the encoder plays as a critic to maximize the distance between the original and transcribed images, in which the distance is measured by rate reduction in the feature space; in the cooperative process, the encoder and the decoder cooperatively minimize the distance to improve the transcription quality. Cooperative adversarial learning possesses the concepts and properties of Auto-Encoding and GAN, and it is unique in that the encoder actively controls the training process as it is trained in both learning processes in two different roles. Experiments demonstrate that without regularization techniques, our generative model is robust to net architectures and easy to train, sample-wise reconstruction performs well in terms of sample features, and disentangled visual attributes are well modeled in independent principal components.
