There is also a piece of code that can produce a single digit, also very plausible: Developing a GAN for generating images requires both a, We don't want just one low-resolution version of the image; we want many parallels versions or interpretations of the input. It is a good practice to use soft labels, such as values slightly more or less than 1.0 or slightly more than 0.0 for real and fake images respectively, where the variation for each image is random. As such, it is also recommended that real images used to train the discriminator are scaled so that their pixel values are in the range [-1, 1]. Generative Adversarial Networks, or GANs, are a deep-learning-based generative model. Key Features Use different datasets to build advanced projects in the Generative Adversarial Network domain Implement projects ranging from generating 3D shapes to a face aging application therefore, we will mark all of the layers in the discriminator as not trainable when it is part of the GAN model so that they cannot be updated and overtrained on fake examples.
