Structure of WideResNet residual blocks. a Structure of the regular residual block. b Structure of the regular residual block with 1 × 1 convolution on the shortcut connection. c Structure of the residual block with dilated convolutions. d Structure of the residual block with dilated convolutions and 1 × 1 convolution on the shortcut connection, where k represents the convolution kernel size, s represents the stride, p represents the padding, and d represents the dilation factor
