initial learning rate is , then at batch i, 1 i m, we will set the learning rate to be i =m. Zero . A ResNet network consists of multiple residual blocks, each block consists of several convolutional lay-ers. Given input x, assume block(x) is the output for the last layer in the block, this residual block then outputs x+ block(x).
