WebResNet. Now, that we have created the ResidualBlock, we can build our ResNet. Note that there are three blocks in the architecture, containing 3, 3, 6, and 3 layers respectively. To make this block, we create a helper function _make_layer. The function adds the layers one by one along with the Residual Block. WebWide ResNet Architecture. A Wide ResNet has a group of ResNet blocks stacked together, where each ResNet block follows the BatchNormalization-ReLU-Conv structure. This structure is depicted as follows: There are five groups that comprise a wide ResNet. The block here refers to the residual block B(3, 3).
