Generative Adversarial Networks (GAN) is one of the most popular models in generative deep learning models. Many derivatives have been published and researches have been conducted in various fields. In this study, we review the derivatives of GAN and compare them. We determine the proper dimension of the latent space and compare the metrics Fréchet Inception distance (FID) and Inception score (IS) which are used for evaluating generated data. The experiments show that GAN-NS and LSGAN works well and FID is superior to IS. And the 10 dimensional latent spaces yield good results, which is not much different from the result of typical 100 dimensions.
Keywords : Deep learning, Fréchet Inception distance, generative adversarial networks, Inception score, latent space.
