  • Patent number: 11315343
    Abstract: The invention relates to an adversarial optimization method for the training process of generative adversarial network. According to the adversarial optimization method for the training process of generative adversarial network, the optimal transmission problem is transformed into solving the elliptic Monge-Ampere partial differential equation (MAPDE) in the generator G. To solve MAPDE of n (n>3) dimensions, the Neumann boundary conditions are improved and the discretization of MAPDE is extended to obtain the optimal mapping between a generator and a discriminator, which constitutes the adversarial network MAGAN. In the process of training the defence network, by overcoming the loss function of the optimal mapping, the defence network can obtain a maximum distance between the two measurements and obtain filtered security samples. The effective attack method of GANs is successfully established, with the precision improved by 5.3%.

  • Patent number: 11308587
    Abstract: The present invention relates to a learning method of generative adversarial network (GAN) with multiple generators for image denoising, and provides a generative adversarial network with three generators. Such generators are used for removing Poisson noise, Gaussian blur noise and distortion noise respectively to improve the quality of low-dose CT (LDCT) images; the generators adopt the residual network structure. The mapped short connection used in the residual network can avoid the vanishing gradient problem in a deep neural network and accelerate the network training; the training of GAN is always a difficult problem due to the unreasonable measure between the generative distribution and real distribution. The present invention can stabilize training and enhance the robustness of training models by limiting the spectral norm of a weight matrix.
