Generative models from lossy measurements
WebGenerative adversarial networks (GANs) [2, 7, 14, 27, 32, 47, 79] aim to model the target distribution using adversarial learning. Various adversarial losses have been proposed to stabilize the training or improve the convergence of the GAN models, mainly based on the idea of minimizing the f -divergence between the real and generated data ... WebNov 27, 2024 · AmbientGAN [7] ( Fig. 2 c) trains a generative model capable to yield full images from only lossy measurements. One of the image degradations considered in this approach is the random removal of pixels leading to sparse pixel map y. It is simulated with a differentiable function fθ whose parameter θ indicates the pixels to be removed.
