                      DECEMBER MEETING ANNOUNCEMENT

DATE: Saturday, December 9, 1989
TIME: 12:30 PM
PLACE: McDermott Library, Room 2.406 (or adjacent room), the University of
       Texas at Dallas
TOPIC: Isomorphic back-propagation networks
SPEAKER: Mike Manry, Electrical Engineering, UTA

Dr. Manry will give an overview of research into methods of mapping signal
processing algorithms onto back-propagation networks.  The signal
processing algorithms include Gaussian classifiers.

A new design technique for back-propagation networks is presented.  In this
technique, unit activation functions are approximated by power series.
Basic building blocks such as monomial networks and multiplier networks are
implemented with any desired degree of accuracy.  Representation theorems
for designing arbitrary continuous functions are also discussed.

These studies will give us a clearer understanding of the strengths,
limitations, and uses of back-propagation networks.  One specific
application being used in this research is recognition of hand-printed
numerals.

DIRECTIONS: UTD is on Floyd Road, north of Campbell Road in Richardson.
Take Central Expressway to the Renner Road exit (north of Campbell Road).
Take Renner Road west past the traffic light at Custer.  You'll have to
curve south as Renner ends at Floyd road.  The main entrance to the UTD
campus is at the (only) stop sign on Floyd between Renner and Campbell.  Go
west into the campus to the parking lot behind the guard station (it is
usually open on Saturday afternoons).  McDermott Library is the building on
the south border of the lot.  We meet in one of the classrooms on the left
after you go in the main entrance which, according to UTD's unique
numbering scheme, is on level two.

                          November Meeting Notes

The presentation on transputers and the Occam language given by David Bye
of INMOS was very informative.  David Bye has complimentary literature
available on transputers, systems, and the Occam language.  If you are
interested, contact him at the SGS Thomson (INMOS) facility at 1310
Electronics Drive in Carrollton.
