Dear readers,
There was an (unintended) holiday for the Digest for the past two weeks.
The end of the Spring semester and the beginning of the summer session
found me with a bit too much on my plate. The Digest necessarily took a
lower priority. I'll try to speed through the backlog. As always,
please mark especially time-sensitive submissions and I will force them
through the queue with alacrity.
Thanks,
Peter

Subject: COURSE ANNOUNCEMENT
From: LOrlando@UNEX.UCLA.EDU
Date: Tue, 20 Apr 93 10:47:00 -0800
UCLA Extension announces a new short course
Wavelet Transform: Techniques and Applications
August 9-11, 1993 at UCLA
For many years, the Fourier Transform (FT) has been used in a wide
variety of application areas, including multimedia compression of
wideband ISDN for teleRcommunications; lossless transform for fingerprint
storage, identification, and retrieval; an increased S/N ratio for target
discrimination in oil prospect seismic imaging; inRscale and
rotationRinvariant pattern recognition in automatic target recognition;
and inRheart, tumor, and biomedical research.
This course describes a new technique, the Wavelet Transform (WT), that
is replacing the windowed FT in the applications mentioned above. The WT
uses appropriately matched bandpass kernels, called mother wavelets,
thereby enabling improved representation and analysis of wideband,
transient, and noisy signals.
This course is taught by Harold Szu, Research Physicist and President of
INNS, and John D. Villasenor of UCLA's School of Engineering and Applied
Science.
To request a brochure, call (310) 825-1047; FAX (310) 206-2815; or
send your external mailing address to:

of deliverable software packages that are put to use by scientists or
NASA operations personnel. The ML subgroup focusses on applications
of machine learning in analysis of large image databases and in the
automated acquisition of diagnostic knowledge from training data.
The work will involve extending the state-of-the-art in machine
learning as well as applications to real-world problems. Publication
of research at major conferences and journals is strongly encouraged
by JPL and NASA.
Other ongoing efforts in the AI Group involve: intelligent system
monitoring, model-based reasoning, planning and scheduling. If you

Subject: About percentage of useful neurons - a glance from Russia
From: Vad Potapov <pvad@ekoram.msk.su>
Date: Sun, 09 May 93 13:30:14 +0200
With the great interest we've read discussion about effective
usage of brain's neurons in BRAIN-L (thanx to Neuron Digest).
In accordance with our concept of formation and functioning of
the brain [you can FTP it from cs.bham.ac.uk, ask Tim Read
T.M.Read@computer-science.birmingham.ac.uk], intelligent abilities
depend on the number of neurons strongly, but not directly. This
dependence is expressed via very hard task of sufficient power supply
for great mass of energy-consuming neurons. Neuronal structures
(cellular unions) had appeared in the evolutionary process to
interchange excitatory and inhibitory signals, because such
interchange promotes minimization of energy consumption of whole
neural network. In fact, the activity of neural network is only the
way of survival.
The main form of brain activity is the sleep. In this state the
brain is able to self-stimulate, but for some reasons this state can't
be endless. Being awake, the brain needs external excitations
(stimulation) for the same purpose - to decrease energy consumption.
Affectory systems deliver such a stimulation, creating at the same
time small stable neuronal formation - memory elements. The brain
simply needs work without regard of sense.
Intelligence and others useful adaptive abilities are only
secondary consequences and can appear in several specific external
conditions.
Our point of view is that the brain must be big enough, but not
for thinking! The more neurons in the brain, the more neurons should
be supplied for survival, the better should be the activity in
external, human sense.
Descriptions of our experiments anybody can find in Biol.Cybern.,
1992, vol.67.

Subject: Brain usage, continued...
From: UAP001%DDOHRZ11.BITNET@DMSWWU1A.UNI-MUENSTER.DE (C.R. Cavonius)
Date: Mon, 10 May 93 09:49:52 +0700
The recent suggestion that we must be using the full capability of our
brains, because evolution wouldn't have created anything so complex and
energy-hungry and then not put it to full use, doesn't hold water. One
of the most astonishing aspects of the development of our brain is that
as far as can be told from crainial volume (the brain itself, sadly,
doesn't leave fossils) the brain had reached its present state by c.
100,000 years ago, at which time humans were living in much the same way
as their ape relatives; and the development of modern society and
technology goes back no more than 20,000 years. What 'drove' the
development of a largely unused brain is a mystery: the usual
evolutionary principle that useful structures tend to be kept seems to
have been leapfrogged in this case.

ANNOUNCEMENT: Associate Editors needed for electronic journal PSYCHE
PSYCHE (ISSN: 1039-723X) is a refereed electronic journal dedicated to
supporting the interdisciplinary exploration of the nature of
consciousness and its relation to the brain. PSYCHE publishes material
relevant to that exploration from the perspectives afforded by the
disciplines of cognitive science, philosophy, psychology,
neuroscience, artificial intelligence and anthropology.
Interdisciplinary discussions are particularly encouraged.
PSYCHE is managed by a committee of volunteers made up of an Executive
Editor and a number of supporting Associate Editors. The Associate
Editors offer practical support in a number of ways to the development of
the magazine, among the most significant being the management of the peer
review of articles in their own field of speciality.
Currently there are openings for two Associate Editors whose fields of
speciality are in either anthropology or philosophy. Applicants are
expected to be actively engaged in research in their areas of
speciality and to have earned a doctorate or have the equivalent
academic background.
Applications will be accepted through June 14, 1993.
Applicants should send their resume to:
Patrick Wilken
Executive Editor
PSYCHE: an interdisciplinary journal of research on consciousness
E-mail: x91007@pitvax.xx.rmit.edu.au
Subscriptions to the electronic version of PSYCHE may be initiated by
sending the one line command: SUBSCRIBE PSYCHE-L Your Name
in the body of an electronic mail message to LISTSERV@NKI.BITNET or
LISTSERV%NKI.BITNET@cunyvm.cuny.edu. In addition there is a discussion
list, PSYCHE-D, devoted to topics related to those of the journal. To

Subject: Request for data-sets
From: Nolan J C <nolajy@essex.ac.uk>
Date: Mon, 24 May 93 14:10:07 +0000
Hi,
I am currently involved in the evaluation of a number of novel neural net
algorithms aimed at increasing the accuracy of forecasting in
manufacturing environments. Initial results are encouraging, but in
order to evaluate the networks further, more data sets are required.
Currently data sets consisting of sales information, economic data,
weather forecasts etc are being utilised, however data sets used in any
aspect of forecasting will be helpful just as long as they consider at
least four variables with a minimum of around 50 samples (or around 2
years). Alternatively any addresses of sites where data-sets of this
nature are available would be great.
Naturally I will attempt to return any help which is given by way of
making available those data-sets which I have which are not restricted by
confidentiality agreements.
