Fig. 2From: Generation of synthetic ground glass nodules using generative adversarial networks (GANs)The structure of the network. The generator creates the synthetic ground glass nodule at the position where the mask in the input. The generator is composed of convolutional layers with a kernel size of 3 × 3, the batch normalisation, and the “parametric rectified linear unit” (PReLU) activation function. The discriminator was composed of convolutional layers with a kernel size of 3 × 3, the batch normalisation, and the leaky PReLU activation functionBack to article page
