对于我而言,平时的习惯是第一种,因为只会遍历grad graph一次,直觉上会觉得快一些。 尽管看起来实现了同样的功能,但实际上,在使用了Spectral Normalization的情况下,只有version 3是正确的。因为Spectral Normalization会在网络每次调用forward()前,对网络的参数进行更新。这意味着只有version 3的loss_real能够计算出正确...
Spectral Normalization 谱归一化 令人拍案叫绝的Wasserstein GAN pytorch的spectral_norm的使用 Thanks 😄

原因也很简单，因为 Batch norm 的“除⽅差”和“乘以缩放因⼦”这两个操作很明显会破坏判别器的 Lipschitz 连续性。// 五、GAN的谱归⼀化实现 google⽤tensorflow实现了谱归⼀化函数 pytorch中有实现好的谱归⼀化函数torch.nn.utils.spectral_norm（）（）import torch.nn as nn import torch ...

Layer normalization acts on each feature of each sample, independently adjusting the statistical properties of each feature to accelerate training and improve the model’s generalization performance. The formula for layer normalization is as follows, where \(X_{conv}^{1D}\) is the output from the...
所有实验均在配备i5-12400F CPU和NVDIA GeForce RTX 3060 GPU和PyTorch 1.3.0深度学习框架和Python 3.9编译器的计算机上进行。训练阶段批尺寸(Batch size)设置为64,训练过程最大迭代次数为200次。 由于Indian Pines数据集空间分辨率较低,存在光谱变异和样本分布不均衡等情况,所以抽取其10%的样本用于训练,Salinas和...
