[comp.ai.neural-nets] Questions About Hopfield Networks

mmm@cup.portal.com (Mark Robert Thorson) (03/20/89)

I have a question or two about Hopfield networks used as associative
memory.  Hopfield says that when multiple parallel networks are driven
from the same clue bus, and drive the same output bus, only the network
containing the memory corresponding to the clue responds (assuming the
memory is stored in one of the networks, and only one of the networks).
In other places, Hopfield says these networks always drive themselves
to a stable state.

My question is:  is there some kind of "null" or "indecision" stable
state?  When multiple memory planes are used, what state do they have
when presented with a memory which they do not hold?
