Subject: Regarding Brain Size and Sulci
From: UAP001%DDOHRZ11.BITNET@CUNYVM.CUNY.EDU
Date: Wed, 19 Dec 90 10:28:56 +0700
On the matter of brain size and number of sulci: exceptions -e.g., Gauss-
have been reported; but there's no clear pattern. A century ago measuring
brains of famous savants was popular, but went out of fashion when it
turned out that geniuses tended to fall into the normal range.
Incidentally, although we don't know the surface area of their cortex,
the Neanderthal probably had slightly larger brains than ours.

I am trying to gather a list of neural networks applications that have,
or are about to, become commercial products. At NIPS we heard about such
work from FORD and Sarnoff labs, I would appreciate any other examples
that any of you are aware of.

[[ Editor's Note: My thanks to Denis for providing this summary. My
frequent theme is for readers who request information to share the
resulst of their search with the Digest so all may benefit. Readers who
post what they're doing may find kindred spirits in unlikely places as

Peter
You stated in the Digest that you would like a summary of the search in
medical/astronomical imaging using neural nets. I give below short notes
on the small number of replies I have had, and a short summary of what I
am doing.
I am not sure how much use the below is, but hopefully the names of
interested users may be of some interest.
nb. I only have medical replies here.
Denis
1. Peter J.B. Hancock (pjh@cs.stir.ac.uk)
Starting looking at MRI brain data, with a view to describing the lesions
caused by accidents, and eventually trying to predict the long-term
recovery of the patient.
2. Paul Marquis (pmarquis@jade.tufts.edu (Internet) PTMARQUI@TUFTS (BITNET))
I'm a graduate student at Tufts University and am currently considering
using neural networks as an approach to Magnetic Resonance.
3. Henk D. Davids (hd%nl.philips.cft.philtis%uucp.phigate@nl.nluug.hp4nl)
We are working with medical images too. I would love to see more
application of nn technology to medical image data discussed here. Seems
to me that there are some problems that are specific for this kind of
processing: the large input space ... I think that there must be
sufficient interest to warrant discussion on Usenet rather than taking
this type of application into a private corner.

Subject: Connectionist Simulators

[[ Editor's Note: Once again, I'm reminded of the need of a "canonical"
list of neural network simulators. I've been meaning to assemble same,
but doubt that I'll have enough free time to do so. Besides this below,
there's also the PDP Volume 3 code, Mactivation, and many other public
domain or low-cost programs. In addition, there is a host of commercial
products. Does anyone keep such a "complete list" which they would share
with the Digest? -PM ]]
Last November, I posted a request for connectionist modeling simulators
to the mailing list. I would like to thank those who responded.
Following is a list and brief description of several simulators:
1. Genesis - An elaborate X windows simulator that is particularly well
suited for modeling biological neural networks.
unix> telnet genesis.cns.caltech.edu (or 131.215.135.185)
Name: genesis
Follow directions there to get a ftp account from which you
can ftp 'genesis.tar.Z". This contains genesis source and
several tutorial demos. NOTE: There is a fee to become a
registered user.
2. PlaNet (AKA SunNet) - A popular connectionist simulator with versions to
run under SunTools, X Windows, and non-graphics terminals
created by Yoshiro Miyata. The SunTools version is not
supported.
unix> ftp boulder.colorado.edu (128.138.240.1)
Name: anonymous
Password: ident
ftp> cd pub
ftp> binary
ftp> get PlaNet5.6.tar.Z
ftp> quit
unix> zcat PlaNet5.6.tar.Z | tar xf -
All you need to do to try it is to type:
unix> Tutorial
This will install a program appropriate for your environment
and start an on-line tutorial. If you don't need a tutorial,
just type 'Install' to install the system and then
'source RunNet' to start it. See the file README for more
details.
The 60-page User's Guide has been split into three separate
postscript files so that each can be printed from a printer
with limited memory. Print the files doc/PlaNet_doc{1,2,3}.ps
from your postscript printer. See the doc/README file for
printing the Reference Manual.
Enjoy!! And send any questions to miyata@boulder.colorado.edu.
3. CMU Connectionist Archive - There is a lisp backprop simulator in the
connectionist archive.
unix> ftp b.gp.cs.cmu.edu (or 128.2.242.8)
Name: ftpguest
Password: cmunix
ftp> cd connectionists/archives
ftp> get backprop.lisp
ftp> quit
4. Cascade Correlation Simulator - There is a LISP and C version of the
simulator based on Scott Fahlman's Cascade Correlation algorithm,
who also created the LISP version. The C version was created by
Scott Crowder.
unix> ftp pt.cs.cmu.edu (or 128.2.254.155)
Name: anonymous
Password: (none)
ftp> cd /afs/cs/project/connect/code
ftp> get cascor1.lisp
ftp> get cascor1.c
ftp> quit
A technical report descibing the Cascade Correlation algorithm
may be obtained as follows:
unix> ftp cheops.cis.ohio-state.edu (or 128.146.8.62)
Name: anonymous
Password: neuron
ftp> cd pub/neuroprose
ftp> binary
ftp> get fahlman.cascor-tr.ps.Z
ftp> quit
unix> uncompress fahlman.cascor-tr.ps.Z
unix> lpr fahlman.cascor-tr.ps
5. Quickprop - A variation of the back-propagation algorithm developed by
Scott Fahlman. A LISP and C version can be obtained in the
same directory as the cascade correlation simulator above.

Subject: Transputers for neural networks?

Date: Wed, 09 Jan 91 12:25:45 +0000
[[ Editor's Note: As usual, I certainly hope that Tom summarizes the
results he gets and posts them to the Digest. Of course, readers with
relevant information are free to post directly to the Digest
(neuron-request@hplabs.hpl.hp.com) as well as sending a copy to Tom. -PM]]
Hi netters,
I am compiling a technical report on scientific/industrial use of
transputers and similar parallel computers (Intel IPSC, NCube, Cosmic
Cube, etc...) for neural network research/applications. If you happen
to be involved both in neural networks and parallel computers, please get
in touch with me.
I'm interested in
* what machine do you use ? And in what language do you program it ?
* what kind of networks do you run on the machine ? feed forward things
like perceptrons, backprop, or more dynamic things like Hopfield,
Kohonen networks ?
* how did you do it ? i.e. how did you handle parallelism
* are you happy ? i.e. how well does the application run ? Do you have
any performance/efficiency measures ?
* what do you use it for ? i.e. do you run simulations for basic network
research ? Are you involved with research on a particular
application and do you use the parallel machine just c'se its
fast ? Do you have an industrial application ? If so, do you sell it?
What price ? Happy clients ?
The idea is to get an overview of what people are doing with neural nets
and parallel computers, how they are doing it, and how well it goes.
When the report is finished, I'll post a note on the net, so anyone
interested can get a copy.
I'm looking forward to massive response; especially from the U.S. and
from industrial users. Don't use the bulletin board, but contact me
directly.
Cheers,
tom

Subject: Kohonen's Network again
From: JJ Merelo <jmerelo@ugr.es>
Date: 10 Jan 91 12:52:00 +0200
I am working on Kohonen network, and I have met lots of trouble
when I have tried to find the correct parameters k1 and k2 on the
learning algorithm. Does anyone know how to find them?
Besides, the convergence of the learning procedure is guaranteed
because of the decreasing nature of the alpha gain factor. But is it
guaranteed that it will converge to the right vectors. In other
clustering algorithms, it does not end until convergence in clustering
mean vectors is reached ( v.g. k-means), and I think this is more
correct.
By the way, is anybody working on Kohonen's network? I have seen
it quoted thousands of times, but the quotes are always from the same
papers from Kohonen himself. I know not about anybody who has got Kohonen
net working ( maybe Aleksander, as he says in his book, but this is the
only one ). I think it *must* work, but I have got mixed results.
Besides, it is boring to keep on trying new parameters.
I hope to get some help,

ADDENDUM TO CALL FOR PAPERS
EIGHTH INTERNATIONAL WORKSHOP ON MACHINE LEARNING
NORTHWESTERN UNIVERSITY
EVANSTON, ILLINOIS
JUNE 27-29, 1991
We wish to clarify the position of ML91 with respect to the issue of multiple
publication. In accordance with the consensus expressed at the business
meeting at ML90 in Austin, ML91 is considered by its organizers to be a
specialized workshop, and thus papers published in its proceedings may overlap
substantially with papers published elsewhere, for instance IJCAI or AAAI.
The sole exception is with regard to publication in future Machine Learning
Conferences. Authors who are concerned by this constraint will be given the
option of foregoing publication of their presentation in the ML91 Proceedings.
The call for papers contained information concerning seven of the eight
individual workshops that will make up ML91. Information concerning the final
workshop follows.

COMPUTATIONAL MODELS OF HUMAN LEARNING
This workshop will foster interaction between researchers concerned with
psychological models of learning and those concerned with learning systems
developed from a machine learning perspective.
We see several ways in which simulations intended to model human learning and
algorithms intended to optimize machine learning may be mutually relevant.
For example, the way humans learn and the optimal method may turn out to be
the same for some tasks. On the other hand, the relation may be more
indirect: modeling human behavior may provide task definitions or constraints
that are helpful in developing machine learning algorithms; or machine
learning algorithms designed for efficiency may mimic human behavior in
interesting ways.
We invite papers that report on learning algorithms that model or are
motivated by learning in humans or animals. We encourage submissions that
address any of a variety of learning tasks, including category learning, skill
acquisition, learning to plan, and analogical reasoning. In addition, we hope
to draw work from a variety of theoretical approaches to learning, including
explanation-based learning, empirical learning, connectionist approaches, and
genetic algorithims.
In all cases, authors should explicitly identify 1) in what ways the system's
behavior models human (or animal) behavior, 2) what principles in the
algorithm are responsible for this, and 3) the methods for comparing the
system's behavior to human behavior and for evaluating the algorithm. A
variety of methods have been proposed for computational psychological models;
we hope the workshop will lead to a clearer understanding of their relative
merits. Progress reports on research projects still in development are
appropriate to submit, although more weight will be given to projects that
have been implemented and evaluated. Integrative papers providing an analysis
of multiple systems or several key issues are also invited.
