I replaced the lsgan loss with wgan/wgan-gp loss (the rest of parameters and model structures were same) for horse2zebra transfer mission and I found that the model using wgan Like WGAN, LSGAN tries to fix the GAN’s notorious hardship of training by limiting the generating capacity. In order to do that, LSGAN stops pushing the distance between the real distribution and the fake distribution when the certain margin is met. Annotated, understandable, and visually interpretable PyTorch implementations of: VAE, BIRVAE, NSGAN, MMGAN, WGAN, WGANGP, LSGAN, DRAGAN, BEGAN, RaGAN, InfoGAN, fGAN, FisherGAN Topics python machine-learning pytorch discriminator generative-adversarial-network gan infogan autoencoder vae wasserstein wgan lsgan began generative-models dragan LSGAN has a setup similar to WGAN. However, instead of learning a critic function, LSGAN learns a loss function. The loss for real samples should be lower than the loss for fake samples. This allows the LSGAN to put a high focus on fake samples that have a really high margin.

divergence 최소화와 같음을 보였다. WGAN: 실제 데이터의 분포와 가짜 데이터의 분포의 거리를 측정하는 방법으로 Wasserstein Distance 를 정의하여 가짜 데이터를 실제 데이터에 근접하도록 하는 방법을 제시하였는데, 기존의 GAN In this lecture Wasserstein Generative Adversarial Network is discussed.#wasserstein#generative#GAN 本文主要介绍了WGAN的核心思想。. 由于JS divergence自身的限制,我们先改进了classifier的输出分数的分布,从sigmoid改成了linear,即LSGAN;还有另外一种改进方式,使用Wasserstein distance来衡量两个分布之间的差异,即WGAN。. JS divergence is not suitable. 在之前的文章中,我们使用了JS divergence来衡量$P_G,P_{data}$之间的差距。. 在大多数的情况中,我们学习出来的分布$P_G$和真实数据的分布 2020-05-18 · Generative Adversarial Networks or GANs is a framework proposed by Ian Goodfellow, Yoshua Bengio and others in 2014.

It’s working directly out-of-the-box without any tweaking necessary. You can increase or decrease the learning rate by a lot without causing many problems. So for this, WGAN-GP really has my appreciation.
