好的,关于 autoencoder pytorch,你可以参考以下代码实现:
```python
import torch
import torch.nn as nn
class Autoencoder(nn.Module):
def __init__(self):
super(Autoencoder, self).__init__()
self.encoder = nn.Sequential(
nn.Linear(28*28, 128),
nn.ReLU(True),
nn.Linear(128, 64),
nn.ReLU(True),
nn.Linear(64, 12),
nn.ReLU(True),
nn.Linear(12, 3))
self.decoder = nn.Sequential(
nn.Linear(3, 12),
nn.ReLU(True),
nn.Linear(12, 64),
nn.ReLU(True),
nn.Linear(64, 128),
nn.ReLU(True),
nn.Linear(128, 28*28),
nn.Tanh())
def forward(self, x):
x = self.encoder(x)
x = self.decoder(x)
return x
```
这是一个简单的三层自编码器,输入为28*28的图像,输出也是28*28的图像。
