For example, the depthwise layer may work on a tensor with 144 channels, which the projection layer will then shrink down to only 24 channels. This kind of layer is also called a bottleneck layer because it reduces the amount of data that flows through the network. (This is where the “bottleneck residual block” gets its name from: the output of each block is a bottleneck.)

So the input and the output of the block are low-dimensional tensors, while the filtering step that happens inside block is done on a high-dimensional tensor.
