Without such a condition, a standard GAN (sometimes called an unconditional GAN) simply relies on mapping the data in the latent space to that of the generated images. The resulting model could then be used as the basis for computer vision in an industrial robot programmed to find and pick mushrooms. For example, a cGAN presented with images of different types of mushrooms along with labels, can be trained to generate and discriminate only those mushrooms which are ready to pick. This can also result in more stable or faster training, while potentially increasing the quality of generated images. The generator simply starts with random noise and repeatedly creates images that hopefully tend towards representing the training images over time.Ī Conditional GAN (cGAN), solves this by leveraging additional information such as label data (aka class labels). Conditional GANĪ challenge with standard GANs is the inability to control the types of images generated. If you need a quick refresher on GANs, check out our blog Exploring Generative Adversarial Networks, where we reviewed how a GAN trains two neural networks: the generator and discriminator that learn to generate increasingly realistic images while improving on its ability to classify images as real or fake. We’ve chosen to take a closer look at these five GANs making headlines today because they provide a wide gamut of functionality ranging from upscaling images to creating entirely new images from text-based descriptions: In order to achieve such results, a number of enhanced GAN architectures have been devised, with their own unique features for solving specific image processing problems. Applications that really benefit from using GANs include: generating art and photos from text-based descriptions, upscaling images, transferring images across domains (e.g., changing day time scenes to night time), and many others. Machine learning practitioners are increasingly turning to the power of generative adversarial networks (GANs) for image processing. Machine learning practitioners are increasingly turning to the power of GANs for image processing, understand these five.
