Subject: inquiry (Electronic/VLSI implementations of neural nets)
From: Francisco Castillo Cobo <castillo@eel.upc.es>
Date: 03 Oct 90 19:14:00 +0100
Hi, I want to hear from people out there who are working on actual
Electronic/VLSI implementations of neural nets. I have already seen a lot
of implementations for the Hopfield net, so I'm really interested in
seeing other types of nets, or if not, someth i ng new in these nets
(like a ckt. that incorporates the learning rules).
I am currently working on a VLSI architecture for the Backprop. algo.,
maybe we could exchange ideas. You may mail me directly at
castillo@eel.upc.es if the subject matter is not of general interest.

Subject: Any Neural-Net Accelerator for the PC?
From: Ran Ginosar <ran%techvlsi.technion.ac.il@CUNYVM.CUNY.EDU>
Date: Fri, 05 Oct 90 00:56:37 +0200
We are looking to buy an accelerator for the PC for neural network
computations. Any recommendations or suggestions as to what's available,
what to buy, or what not to buy? Please mail directly to
"ran@ee.technion.ac.il" and I will summarize the results for the net.

Subject: Would anyone take on a part-time research student?
From: Andy Holyer <and@ux.rfhsm.lon.ac.uk>
Date: Mon, 08 Oct 90 15:04:00 +0000
I have been granted the concession from my department of being able to
devote a certain amount of my time on research work (if I can get a
project going). I need currently to get some form of postgrduate
qualification (to cover up my undergraduate degree), and I would like to
start an M.Phil./Ph.D; I'd like to look at connectionism. Is there anyone
out there who would take on a part-time, external research student?
There's nobody here who even knows what a NN is, letalone being
interested in supervising.
Any fees incurred I could *probably* be able to cover out of my
own resources. For obvious reasons my order of preference for locations
is London/S.E. England/U.K./Europe/Anywhere else :-)
If anyone's willing to help, mail me directly and we can talk
about the things I'm interested working on.

maps. It' s a modified version of Algenion algorithm presented on Neural
Networks Vol 1 pag. 289-293,1988. I kindly request some "standard"
benchmarks (sets of cities coordinates) to test the program. If somebody
request it I' ll send the source code.

Subject: Paper on Conjugate Gradient Backpropagation
From: erik@adams.llnl.gov (ERIK JOHANSSON)
Date: Tue, 02 Oct 90 17:25:24 -0700
Some time ago I wrote about our work using conjugate gradient methods to
improve backpropagation learning times. At the time, I mentioned that I
had a paper in the works which was soon to be completed. Unfortunately,
my work schedule did not permit me to complete it until last week. In
any event, it is now available. You can get a post script copy via
anonymous ftp (described below). If this is not satisfactory, please
e-mail me a request and I will mail you a hardcopy. The title and
abstract are included here:
"Backpropagation Learning for Multi-Layer Feed-Forward
Neural Networks Using the Conjugate Gradient Method"
E. M. Johansson
F. U. Dowla
D. M. Goodman
Lawrence Livermore National Laboratory
Abstract --- In many applications, the number of interconnects or weights
in a neural network is so large that the learning time for the
conventional backpropagation algorithm can become excessively long.
Numerical optimization theory offers a rich and robust set of techniques
which can be applied to neural networks to improve learning rates. In
particular, the conjugate gradient method is easily adapted to the
backpropagation learning problem. This paper describes the conjugate
gradient method, its application to the backpropagation learning problem,
and presents results of numerical tests which compare conventional
backpropagation, steepest descent, and the conjugate gradient methods.
For the parity problem we find that the conjugate gradient method is an
order of magnitude faster than conventional backpropagation with
momentum.

Organized by CISE Tecnologie Innovative and Dipartimento di
Informatica of Universita` di Torino
This workshop (which follows the successful one held at Stanford
University in 1990) encourages intensive and high quality interaction and
cooperation among researchers with a diversity of artificial intelligence
approaches to diagnosis. Attendance will be limited to fifty participants
with presentations spread over three days. Substantial time will be
reserved for discussion.
To attend, participants should submit papers (maximum 5000
words) to be reviewed by the committee. Submissions are
welcomed on (but not limited to) the following topics:
o Theory of diagnosis (abductive vs. deductive diagnosis, isolation vs.
identification, diagnosis on non-monotonic theories, diagnosis of
dynamic systems,...)
o Computational issues (controlling the combinatorial explosion, focusing
strategies, controlling diagnostic reasoning of complex systems, ...)
o Modeling for diagnosis (multiple, approximate, probabilistic and
qualitative models, integrating model-based diagnosis with heuristics ....)
o Evaluation of theories on practical applications
o Inductive approaches to diagnosis (Case-Based Reasoning, Neural Nets, ...)
Accepted papers can be revised for inclusion in the workshop working
notes. Although work published elsewhere is acceptable, new original work
is preferred.
Please send five copies of each submission to the chairman at the postal
address below. Include several ways of contacting the principal author in
addition to a postal address: electronic mail, fax and telephone numbers
