Hitachi Announces General Purpose Neural Computer

NEW YORK, NEW YORK (NB) P Hitachi, Ltd. has announced the development of a
general-purpose neural computer with learning circuits that can carry out up
to 2.3 billion operations per second.  The new neural computer was unveiled
at "Hitachi Technology 1991," a technology fair being held at New York's
Marriott Marquis Hotel from November 26-28.

Hitachi's announcement states that the new system has the highest learning
performance ever achieved by such a computer. It includes 1,152 neurons and
measures 12 inches high, 8.3 inches wide and nine inches deep.  Hitachi also
has developed stock price prediction and signature verification applications
which can be run on a workstation linked with the neural system.  A stock
price prediction has been timed at ten seconds while signature verification
took two seconds.  In describing the differences between standard digital
computers and neural systems, the announcement stated: "A neural computer is
an information processing system which uses a neural network modeled on the
human brain.  The Neumann-type computers in common use today can handle
problems amenable to numerical, comparative, and other types of logical
processing at very high speeds.  These systems, however, are dawdlers when
it comes to tasks that require intuition, such as optimization and pattern
recognition. On the other hand, the neural computer - like the human brain
that it imitates - is poor at numerical calculations, but adept at solving
problems that involve optimization. Another feature that sets the neural
computer apart is its ability to learn.  Like the human brain, the neural
computer can quickly store huge quantities of information and come up with
an optimized solution almost instantaneously."
