The Seeing Stack
Captions available
The idea
A convolutional network stacks template maps feeding template maps, with bends and coarsening between — each small neighborhood's strongest response kept, the rest shed.
In practice
Stacked layers grow each output's field of influence until a final response can depend on the whole image; competition-era stacks ran past 150 layers.
Where people slip
The coarsening buys tolerance to small shifts — and spends fine position information to get it.
