- 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](../Convolutional%20Layer.md)
- Elementwise addition
- All layer 3x3 kernel
- Spatial size halves each layer
- Filters doubles each layer
- [Fully convolutional](FCN.md)
- No fc layer
- No [pooling](../Max%20Pooling.md)
- Except at end
- No dropout
