Subject: definition of a von Neumann machine
Does anyone have an opinion about the definition of a von Neumann
machine? I have always though that it implied the separation of
the memory and the processor (logic). With this in mind, I would
then say that true neural network implementations (resistor arrays,
'blown-fuse' arrays) are not von Neumann machines. But what
about systolic arrays? Even though there is a separation between
the memory and the processor, there is no contention - each
systolic processor has its own block of memory.
Any ideas, beliefs, comments, opinions?

Subject: Three questions:
Are you maintaining a list of subscribers, their current research
projects, interests, meta-net addresses, etc? If so, will it appear
periodically in the digest?
[yes, but it is VERY long - MTG]
Is anyone else on the net trying to keep a current _refer_ or Unix _bib_
bibliography of neural network, connectionist literature? If so,
perhaps we can use your node as a database server to keep our local
copies current.
[although I can store information on my computer, I cannot give
others access to it! I am unsure of the proper action to take
here - any ideas? - MTG]
Lastly, does anyone else want to exchange code? I have some modula-2
code which runs on Suns, Macintosh, and Ceres, which graphically shows
neurons, their connections, and firing status. Next semester, a
student will start interfacing the graphical display to a real
network. At the moment, the code has the neurons fire randomly, and
connections change randomly.
I would like some simple Feldman and Ballard P and Q models code for
Unix (C, I suppose).

P.S. Please use the second address (arpa, csnet) if possible. It is
faster and cheaper.

Subject: AXON
Has a language specification/description of AXON been published?
(If so, I'd appreciate pointers.)
Advance thanks,

Re: Cognitive Studies Speaker Series
TITLE: Hypotheses Underlying Connectionism
SPEAKER: Paul Smolensky, University of Colorado
DATE: Monday, February 16
LOCATION: Princeton University, Green Hall, Langfeld Lounge
TIME: 12:00 - 1:15 p.m.
Abstract
Cognitive models using massively parallel, nonsymbolic computa-
tion have now been developed for a considerable variety of cogni-
tive processes. What are the essential hypotheses underlying
these connectionist models? A satisfactory formulation of these
hypotheses must handle a number of attacks:
* nothing really new can be offered since Turing machines are universal
* connectionism just offers implementation details
* conscious, rule-guided behavior is ignored
* the wrong kind of explanations are given for behavior
* the models are too neurally unfaithful
* logic, rationality, and the structure of mental states are ignored
* useful AI concepts like frames and productions are ignored
I will give an introduction to connectionist models, describe the
kind of computation they use, and present a general connectionist
approach that faces the challenges listed above.

Subject: Conference Announcement
Neural Models of Plasticity: Theoretical and Empirical Approaches
April 29, 1987 to May 1, 1987
Marine Biological Laboratory
Woods Hold, Massachusetts
PROGRAM:
Two separate approaches, one theoretical and the other empirical,
are being used currently to explore the role of neuronal
plasticity in learning, memory and complex brain functions. The
theoretical approach attempts to simulate and synthesize brain
function with mathematical models based on known and hypothesized
principles of neural function. The empirical approach attempts
to delineate the detailed biochemical and biophysical properties
of neurons, the rules that determine their connectivity, and the
mechanisms through which their properties and connections are
modified during learnign. The purpose of this conference is to
review recent developments in both areas and to foster
communication between those researchers pursuing theoretical
approaches and those pursuing more empirical approaches.
