Artificial Intelligence By Example

Kernel

Just to get started, intuitively let's take another everyday model. This model is a bit more mathematical and closer to CNN's kernel representation. Imagine a floor of very small square tiles in an office building. You would like each tile of the floor to be converted from dirty to clean, for example. You can imagine a cleaning machine converting 3 x 3 small tiles (pixels) at a time from dirty to clean. You would laugh if you saw somebody come with 50 cleaning machines to clean all of the 32 x 32 tiles (pixels) at the same time. You know it would consume more resources, intuitively. Not only is a kernel an efficient way to filter but also a kernel convolution is a time-saving resource process. The single cleaning machine is the kernel (dirty-to-clean ...
