那么 LSGAN 就想通过修改计算 loss 的公式,将 sigmoid 替换成 least squares. 下面第一张有 log 的图是 sigmoid 方式, 而下面第二张没有 log 计算,取而代之的是利用方差的模式,也就是 MeanSquaredError 的计算公式了。这样,能传递回去的梯度就大很多了,理想情况下, 更新GAN的效果也会好很多。 LSGAN相对后面...

LSGANs基本思想 LSGANs的英文全称是Least Squares GANs。这篇文章针对的是标准GAN生成的图片质量不高以及训练过程不稳定这两个缺陷进行改进。改进方法就是将GAN的目标函数由交叉熵损失换成最小二乘损失,而且这一个改变同时解决了两个缺陷。 为什么最小二乘损失可以提高生成图片质量? 我们知道,GANs包含两个部分:判别...
