Layers

[Peter Todd]

I would, in fact, argue AGAINST that definition, because, for instance, in the
following example:

                     O  O
                    /|\ |\
                   / | \| \
                  |  O  O  |
                   \ | /| /
                    \|/ |/
                     O  O    (O's are units, all rest are connections)

we have a TWO layer network (max. number of weights from input units to any
other units) and yet EVERY non-input unit is in the FIRST layer (min. number 
of weights from input unit to any unit).  Seems pretty counterintuitive.
