See python train.py --help for the full list of options and Training configurations for general guidelines & recommendations, along with the expected training speed & memory usage in different scenarios. Lets create a function to generate the latent code, z, from a given seed. The latent vector w then undergoes some modifications when fed into every layer of the synthesis network to produce the final image. Current state-of-the-art architectures employ a projection-based discriminator that computes the dot product between the last discriminator layer and a learned embedding of the conditions[miyato2018cgans]. A typical example of a generated image and its nearest neighbor in the training dataset is given in Fig. GIQA: Generated Image Quality Assessment | SpringerLink further improved the StyleGAN architecture with StyleGAN2, which removes characteristic artifacts from generated images[karras-stylegan2]. They also discuss the loss of separability combined with a better FID when a mapping network is added to a traditional generator (highlighted cells) which demonstrates the W-spaces strengths. artist needs a combination of unique skills, understanding, and genuine To alleviate this challenge, we also conduct a qualitative evaluation and propose a hybrid score. The noise in StyleGAN is added in a similar way to the AdaIN mechanism A scaled noise is added to each channel before the AdaIN module and changes a bit the visual expression of the features of the resolution level it operates on. This regularization technique prevents the network from assuming that adjacent styles are correlated.[1]. StyleGAN also incorporates the idea from Progressive GAN, where the networks are trained on lower resolution initially (4x4), then bigger layers are gradually added after its stabilized. The resulting approximation of the Mona Lisa is clearly distinct from the original painting, which we attribute to the fact that human proportions in general are hard to learn for our network.
