GAN 是强大的生成模型，但存在训练不稳定性的问题. 最近提出的（WGAN）在遗传神经网络的稳定训练方面取得了进展，但有时仍然只能产生较差的样本或无法收敛 WitrynaThe Wasserstein loss function is very simple to calculate. In a standard GAN, the discriminator has a sigmoid output, representing the probability that samples are real or generated. In Wasserstein GANs, however, the output is linear with no activation function! Instead of being constrained to [0, 1], the discriminator wants

Witryna10 kwi 2024 · Gulrajani et al. proposed an alternative to weight clipping: penalizing the norm of the critic’s gradient concerning its input. This improved the Wasserstein GAN (WGAN) which sometimes still generated low-quality samples or failed to converge.
