Dr. Widrow asked me to relay this message in response the journal problem:
I have received several complaints from INNS members about not receiving
their copies of the journal NEURAL NETWORKS. If this has happened to you,
please accept my apology. The person who is now in charge of membership is:
Frank Polkinghorn
9202 Ivanhoe Road
Ft. Washington, MD 20744
Frank is working hard to allieviate the logjam. I am pleased to report that
INNS has grown from zero to 4000 members in a little over one year. We are
having some "growing pains." If you do not receive you journals within
about a month, write to Frank and let him know the facts of your situation.
I am sure that he will get your journals to you soon.
Sincerely,
Bernard Widrow
President INNS

I paid in September, heard nothing until November, and then received Vol. 1,
No. 4 from Pergamon Press. Then, just yesterday, Vol. 1, Nos. 1-3 arrived,
as well as the abstracts from the September INNS meeting held in Boston. So
now I'll probably renew.

Subject: Post-processing of neural net output
From: mesard@BBN.COM

A large portion of existing feedforward nets take an input vector and
produce an encoded boolean response on their outputs (e.g., yes/no,
left/right, signal/noise).
Typically, the output is interpreted based on the activation of a singleton
output unit exceeding some threshold, or whether the activation of one unit
is larger than another.
This approach may mean throwing away a lot of information. Even if the
activation fails to meet some criterion, it might be useful as a similarity
measure, or a rating of the net's confidence in its output. Furthermore,
the criterion could be adjusted based on the discriminablity between outputs
in the positive and negative cases.
Does anyone know of any work that has been done in this area?

The value of an output unit is highly correlated with the confidence of a
binary categorization. In our study of predicting protein secondary
structure (Qian and Sejnowski, J. Molec. Biol., 202, 865-884) we have
trained a network to perform a three-way classification. Recently we have
found that the real value of the output unit is highly correlated with the
probability of correct classification of new, testing sequences. Thus, 25%
of the sequences could be predicted correctly with 80% or greater
probability even though the average performance on the training set was only
64%. The highest value among the output units is also highly correlated
with the difference between the largest and second largest values. We are
preparing a paper for publication on these results.

*** SECOND POSTING ON SIMILARITY METRICS ***
About a month ago I posted a request for information, and interest, in the
area of "similarity metrics". I am posting a second call for information
now with the hope of furthering my base of understanding, and also to
develop a base for the semi-formal survey I will be sending all respondents
(this will be out in a week or so).
I have received feedback from about thirty people. Most of the respondents
have described their interests in this area, and many have provided
abstractions of their methods for measuring similarity. This is very
encouraging and I hope it continues. The survey will also be sent to a
sizeable number of researchers that I know of already. My hope is to make
this a cross-discipline study that provides insight from the Case-Based
Reasoning, Analogical Reasoning, EBL, Information Retrieval, Behavioral
Studies, Machine Learning, Child Psychology, etc. fields.
At present a proposal for holding a workshop on this topic at IJCAI has been
decided against. The topic may be presented as a panel discussion at a
focused Case-Based Reasoning Workshop this year.
--------------------- Original (edited) posting follows -------------------
SIMILARITY ... What does it mean?
for ANALOGY What are the measures?
for REMINDING Are there generalities or is it domain-specific?
for EXEMPLARS ... Eliciation strategies, cues, weights, features, etc.
I am performing independent research in the area of Case-Based Reasoning,
CBR, and I am working on various metrics for similarity.
In general, what ideas do you (the net-world) have about:
- What about a new situation reminds you of a prior experience?
- OR
- How does one situation remind you of another?
A little more focus might be how does one discriminate and weigh features of
a new situation (case) in relationship to a large case-base of experiences
that may or may not have a bearing on the new situation. Did that provide
more focus or fuzziness!?
This notice is sent out as a preliminary "attention-getter" to provide
myself with some input to help form a more formal survey. Once written I
hope to send it to a specific set of researchers (consisting mostly of
people in the CBR, information retrieval (IR), doc. mngt. areas) and to
anyone in netland that requests so.
If anyone is interested in responding to any of this:
- I will watch the "nets" for replies
- Email to: j.a.king@dayton.ncr.com
- Call: (513)-445-1090 before 4:30 (EST) (317)-478-5910 after 6:00
- Mail: NCR Corp. 1700 S. Patterson WHQ-5E Dayton, OH 45479
The survey will be finished and sent in the next week or two, so please let
me know of your interest and what YOU might like to get out of such a study.
Thank you for your time.

[[ Editor's note: I got thisnotice and then lost it. I did make it to the
talk, though, which was quite interesting. Dr. Baggi, a music professor,
gave some very nice aural demonstrations of "computer-generated" swing, but
was a little short on explaining the actual connectionist implementation.
His approach would be best described as classic expert-system style, in
which he hand fed the possibilities and structures and used the simulator
for not much more than "Mozartian dice." So far, he seems to have found no
particular advantage to the connectionist architecture, apart of the ease of
programming "paralell" events. Training the network to analyze swing and
*then* synthesize new music would be most intriguing, but he said that he
wouldn't work on that any time soon. -PM ]]
The International Computer Science Institute
is pleased to present a talk:

"A Connectionist Model for the Synthesis of
Swing in Afro-American Jazz"
Dr. Denis Baggi
University of California, Berkeley
The introduction of computer technology to problems of music and
musicology is as old as computer science and goes back to Charles Babbage
and Ada Lovelace. Starting with the Illiac Suite in 1956, considerable
progress has been achieved both in computer assisted sound synthesis and in
algorithms for symbol manipulation in composition and music analysis.
Several centers - Bell Labs., CCRMA at Stanford, IRCAM in Paris, the
Experimental Music Studio at MIT - have been dedicated to these problems.
With less than half-a-dozen exceptions, however, no results of
applications of computer techniques have been obtained for the
psychoacoustical, perceptual problem of swing in Afro-American Jazz.
Properly, and holistically, defined, swing is the medium of the Jazz message
- as space is the medium of sculpting. Technically, swing consists of
patterns of rhythmic accentuations and tension-release acoustical devices
which are almost instinctively perceived by the listener - though an
analytic description, let alone a teaching methodology, is elusive.
This talk describes some work in progress for the construction of a
connectionist model for the synthesis of swing. Using the Rochester
Connectionist Simulator at the International Computer Science Institute in
Berkeley, a system is being developed which accepts as input the harmonic
grid of a Jazz standard and which constructs the lines played by a rhythm
section consisting of piano, bass and drums. The main program is built
around a connectionist network consisting of several automata running in
parallel such that control passes from one to the other. The output drives a
digital sound synthesis machine. Some preliminary results will be played and
discussed.
This talk will be held in the Main Lecture Hall at ICSI.
