然而,从WGAN的证明来看,尽管LSGAN优化的目标不是KL散度了,而是皮尔森卡方散度,它们并没有本质上的变化,用divergence衡量两个分布的相似程度,避不开零测集的问题,训练仍然会震荡。代码 1. tensorflow/pytorch: wiseodd/generative-models

模型找是是网上找的pytorch实现的lenet,我把训练的次数调大了,发现训练集loss值在50次左右前是一直减小的,但之后逐渐增大,200多次后就大到和初始偏差值差不多了,重复多次依旧。 如果用的sgd,可以考虑在后期对学习率进行衰减,后期学习率太大是有可能

Generative Adversarial Networks (GANs) are powerful generative models, but suffer from training instability. The recently proposed Wasserstein GAN (WGAN) makes progress toward stable training of GANs, but sometimes can still generate only low-quality samples or

The differences in implementation for the WGAN are as follows: Use a linear activation function in the output layer of the critic model (instead of sigmoid). Use -1 labels for real images and 1 labels for fake images (instead of 1 and 0). Use Wasserstein loss to train

In WGAN, they suggest that JS Divergence can not provide enough information when the discrepancy is too large. In contrast, Wasserstein Distance is much more accurate even when two distributions do not overlap. However, it is impossible to calculate
