elsewhere. At this point, we are simply dealing with a black box
having three photographic inputs and sufficient outputs to determine

There is no reason to limit compact encoding to binary
subclasses, although the situation can rapidly become quite complex.
Serious consideration should be given to separate subclasses whenever
the classes are separable. For example, consider a network that must
listen to a spoken sound and provide some classification information.
Its task might be to decide whether the startin ...
