[[ See Editor's Note at the end. ]]
I can't see how you let that "educational stock market game" through.
What if I send you something asking people for money for an
"educational" poker game where I'd be willing to give part of my take
(for running the game) to the winner? A scam is a scam and you've
just helped facilitate one for 50 bucks a pop. This belongs in
Atlantic City, not on the net.

[[ Editor's Note: Because of Gary's note, I reread last issues's
submission of the stock market game and completly agree with him. I had,
in fact, completely missed the entry fee portion of the message; if I had
understood, I probably would not have accepted it for publication. I
know of other "stock market games" which do not require entry fees and
had assumed this was similar. As long-time readers know, I routinely
reject only two types of articles: Jobs *wanted* (i.e., resumes) and
blatantly commercial postings designed primarily for financial gain. In
retrospect, the "stock market game" falls under the second category and
violates the non-commercial intent of the Internet. I strongly recommend
Neuron Digest readers *not* participate. -PM ]]

* MOLECULAR SCENE ANALYSIS *

The concept of "scene analysis" has been used in the context of
machine vision to refer to the set of processes associated with the
classification and understanding of complex images. Such analyses rely on
the availibility of domain knowledge in the form of structural templates,
rules or heuristics to locate and identify features in a scene. By
analogy we use the phrase "molecular scene analysis" to refer to the
processes associated with the reconstruction and interpretation of
molecular structures and molecular interactions. This presentation, in
three parts, will describe some fundamental aspects of the Molecular
Scene Analysis project.
Computational Imagery : Janice Glasgow
- ---------------------------------------
At the core of our knowledge-based approach to molecular
scene analysis is the concept of imagery, that is the ability to reason
with three-dimensional images of molecular structure. To provide a
computational framework that can imitate the human visualization
abilities, we are designing image representations that make explicit the
fundamental spatial and visual charactersitics of a molecular scene.
Applying the computational reasoning techniques of molecular imagery to
the information accumulated in a crystallographic knowledge base provides
the "intelligence" vital to molecular scene analysis.
>From Databases to Knowledge Bases : Frank Allen
- -----------------------------------------------
Full 2D chemical and 3D crystallographic (coordinate) data for
180,000 crystal structures are now held in computerized databases.
Geometric results derived from these data form the basis for the
systematic acquisition of chemical and structural knowledge. This
knowledge may be expressed in terms of numerical values (e.g. typical
geometries), chemical and structural concepts (e.g. conformational
descriptors), or as algorithmic relationships (e.g. correlations between
parameters). A variety of knowledge acquisition methods that can help
transform the crystallographic databases into knowledge bases will be
illustrated.
Conceptual Clustering Applications to Crystallographic Data :
- ---------------------------------------------------- Suzanne Fortier
-----------------
Our research in machine learning is motivated by the need for
techniques to structure, manage and compress the rapidly growing
crystallographic databases and transform them into knowledge bases. An
incremental conceptual clustering algorithm, specifically designed for
objects/scenes composed of many parts, has been designed and implemented.
The algorithm and an initial application to pyranose sugar data will be
described.

Some time ago we released the software package "LVQ_PAK" for the easy
application of Learning Vector Quantization algorithms. Corresponding
public-domain programs for the Self-Organizing Map (SOM) algorithms are
now available via anonymous FTP on the Internet.
"What does the Self-Organizing Map mean?", you may ask --- See the
following reference, then: Teuvo Kohonen. The self-organizing map.
Proceedings of the IEEE, 78(9):1464-1480, 1990.
In short, Self-Organizing Map (SOM) defines a 'non-linear projection' of
the probability density function of the high-dimensional input data onto
the two-dimensional display. SOM places a number of reference vectors
into an input data space to approximate to its data set in an ordered
fashion.
This package contains all the programs necessary for the application of
Self-Organizing Map algorithms in an arbitrary complex data visualization
task.
This code is distributed without charge on an "as is" basis. There is no
warranty of any kind by the authors or by Helsinki University of
Technology.
In the implementation of the SOM programs we have tried to use as simple
code as possible. Therefore the programs are supposed to compile in
various machines without any specific modifications made on the code. All
programs have been written in ANSI C. The programs are available in two
archive formats, one for the UNIX-environment, the other for MS-DOS. Both
archives contain exactly the same files.
These files can be accessed via FTP as follows:
1. Create an FTP connection from wherever you are to machine
"cochlea.hut.fi". The internet address of this machine is
130.233.168.48, for those who need it.
2. Log in as user "anonymous" with your own e-mail address as password.
3. Change remote directory to "/pub/som_pak".
4. At this point FTP should be able to get a listing of files in this
directory with DIR and fetch the ones you want with GET. (The exact
FTP commands you use depend on your local FTP program.) Remember
to use the binary transfer mode for compressed files.
The som_pak program package includes the following files:
- Documentation:
README short description of the package
and installation instructions
som_doc.ps documentation in (c) PostScript format
som_doc.ps.Z same as above but compressed
som_doc.txt documentation in ASCII format
- Source file archives (which contain the documentation, too):
som_p1r2.exe Self-extracting MS-DOS archive file
som_pak-1.2.tar UNIX tape archive file
som_pak-1.2.tar.Z same as above but compressed
An example of FTP access is given below
unix> ftp cochlea.hut.fi (or 130.233.168.48)
Name: anonymous
Password: <your email address>
ftp> cd /pub/som_pak
ftp> binary
ftp> get som_pak-1.2.tar.Z
ftp> quit
unix> uncompress som_pak-1.2.tar.Z
unix> tar xvfo som_pak-1.2.tar
See file README for further installation instructions.
All comments concerning this package should be
addressed to som@cochlea.hut.fi.

Neural-Network Audio Synthesizer Debuts at Paris Opera House
************************************************************
Palo Alto, California -- The old Opera House in Paris, France, will
feature five performances by the Merce Cunningham Dance Company, November
12 to 17, in which a new type of audio synthesizer based on an artificial
neural network will be used to generate electronic music. The
synthesizer's musical accompaniment was composed and will be performed by
David Tudor and his dance company colleague, Takehisa Kosugi.
The audio synthesizer is built around an integrated-circuit chip from
Intel Corporation in Santa Clara, California. The chip, called the Intel
80170NX electrically trainable analog neural network (ETANN), simulates
the function of nerve cells in a biological brain.
A remarkable range of audio effects can be generated with the electronic
synthesizer -- from unique space-age and science-fiction sounds to
passages that sound very much like birds, heart beats, porpoises,
engines, and acoustical, percussion or string musical instruments. Sounds
are generated internally by the synthesizer. External inputs such as
voice, music, or random sounds can optionally be used to enrich or
control the internally generated sounds. In addition to generating
outputs to multiple audio speakers, the synthesizer can simultaneously
drive oscilloscopes or other visual devices.
The neural network chip's software consists of numeric values
representing interconnection strengths between inputs and outputs -- a
configuration analogous to the excitatory or inhibitory strengths of
synapse connections between biological nerve cells. The artificial
neurons can be connected in loops, using the programmable interconnection
strengths, or they can be connected outside the chip with cables and
feedback circuits. Audio oscillations occur as a result of delay in the
feedback paths and thermal noise in the neural network chip. The sounds
are generally rich because of the complexity of the circuitry.
The concept for the synthesizer evolved from a project begun in 1989 by
Forrest Warthman and David Tudor. The synthesizer was designed and built
by Warthman; Mark Thorson, a hardware designer and associate editor of
Microprocessor Report; and Mark Holler, Intel's program manager for
neural network products.
John Cage visited the design group in Palo Alto a few months before his
passing away at the age of 79 this year. His observations on the
synthesizer's role in musical composition and dance performance
contributed to its current design.
A description of the synthesizer's architecture and circuitry will appear
in the February 1993 issue of Dr. Dobb's Journal.
