modules.resnet.AE1d¶
net = mdnc.modules.resnet.AE1d(
channel, layers, block='bottleneck',
kernel_size=3, in_planes=1, out_planes=1
)
This moule is a built-in model for 1D residual auto-encoder. The network structure is almost the same as mdnc.modules.resnet.UNet1d but all block-level skip connections are removed. Generally, using mdnc.modules.resnet.UNet1d should be a better choice.
The network would down-sample and up-sample the input data according to the network depth. The depth is given by the length of the argument layers. The network structure is shown in the following chart:

linkStyle 0,1,2 stroke-width:4px, stroke:#800 ;
linkStyle 3,4,5 stroke-width:4px, stroke:#080 ;The argument layers is a sequence of int. For each block \(i\), it contains layers[i-1] repeated residual blocks (see mdnc.modules.resnet.BlockPlain1d and mdnc.modules.resnet.BlockBottleneck1d). Each down-sampling or up-sampling is configured by stride=2. The channel number would be doubled in the down-sampling route and reduced to ½ in the up-sampling route.
Arguments¶
Requries
| Argument | Type | Description |
|---|---|---|
channel | int | The channel number of the first hidden block (layer). After each down-sampling, the channel number would be doubled. After each up-sampling, the channel number would be reduced to ½. |
layers | (int,) | A sequence of layer numbers for each block. Each number represents the number of residual blocks of a stage (block). The stage numer, i.e. the depth of the network is the length of this list. |
block | str | The residual block type, could be:
|
kernel_size | int | The kernel size of each residual block. |
in_planes | int | The channel number of the input data. |
out_planes | int | The channel number of the output data. |
Operators¶
__call__¶
y = net(x)
The forward operator implemented by the forward() method. The input is a 1D tensor, and the output is the final output of this network.
Requries
| Argument | Type | Description |
|---|---|---|
x | torch.Tensor | A 1D tensor, the size should be (B, C, L), where B is the batch size, C is the input channel number, and L is the input data length. |
Returns
| Argument | Description |
|---|---|
y | A 1D tensor, the size should be (B, C, L), where B is the batch size, C is the output channel number, and L is the input data length. |
Properties¶
nlayers¶
net.nlayers
The total number of convolutional layers along the depth of the network.
Examples¶
Example
1 2 3 4 5 | |
The number of convolutional layers along the depth is 59.
