The Four-Quadrant Problem

[chrisley.pa@Xerox.COM]

In the truly general case of an infinite plane, it seems that the four-quadrant
problem cannot be solved by a (finite) two-layer network.  But for any
arbitrarily large, finite sub-plane, a two-layer (one hidden layer) network
exists that can solve the four-quadrant problem, provided you use an inequality
to interpret the output node.

I think.
