- Residual networks
|
||
|
- 152 layers
|
||
|
- Skips every two layers
|
||
|
- Residual block
|
||
|
- Later layers learning the identity function
|
||
|
- Skips help
|
||
|
- Deep network should be at least as good as shallower one by allowing some layers to do very little
|
||
|
- Vanishing gradient
|
||
|
- Allows shortcut paths for gradients
|
||
|
- Accuracy saturation
|
||
|
- Adding more layers to suitably deep network increases training error
|

# Design
|
||
|
|
||
|
- Skips across pairs of conv layers
|
||
|
- Elementwise addition
|
||
|
- All layer 3x3 kernel
|
||
|
- Spatial size halves each layer
|
||
|
- Filters doubles each layer
|
||
|
- Fully convolutional
|
||
|
- No fc layer
|
||
|
- No pooling
|
||
|
- Except at end
|
||
|
- No dropout
