AI Architecture 12. Skip Connection: ResNet and Bottlenecks
In the previous MLP and Memory Wall, we discussed the "memory wall" phenomenon, where memory bandwidth limits system performance. In CNN and Locality,

AI Architecture 11. Depthwise Separable Conv: The MobileNet Paradox
In the previous 3 Mappings of Conv Operations, we looked at a strategy to sacrifice memory and gain computational speed (GEMM) through the Im2Col method when processing standard convolutions in hardware.
