Subject: Learning to Represent Knowledge in Brain-Style ... (CMU)
[excerpted from NEURON DIGEST V2 #6]
TOPIC: Learning to Represent Knowledge in Brain-Style Computational
Networks
SPEAKER: David E. Rumelhart, U. of California, San Diego
WHEN: Tuesday, February 24, 1987, 3:30 pm
WHERE: Wean Hall 5409
ABSTRACT: The issue of knowledge representation is central to Cognitive
Science and Artificial Intelligence. The difference between an easy problem
and a difficult one is often in the way knowledge is represented. This is as
true in brain-style "connectionist" networks as in symbol processing systems.
It is frequently the choice of representation which makes the difference
between a system which works and a system which does not. Most learning
systems are stuck with the representations which their creators endowed them.
The real learning question is "How can we learn the representations
appropriate to the environment in which we find ourselves?" It was the
inability to modify its rather impoverished representations which led to the
rejection of the Perception. Because of the simplicity and uniformity of
representations within "connectionist" systems we have now been able to
develop learning procedures which not only learn "what to do" in various
situations, but learn "how to represent" the information they must deal with.
This immeasurable increases the power of such networks. The nature of this
learning procedure and a number of examples illustrating the impact of such
learning will be described.

Subject: Announcement: IJCAI Research Excellence Award
THE 1987 IJCAI AWARD FOR RESEARCH EXCELLENCE
I regret to announce that the IJCAI-87 Awards Committee,
having considered all the candidates nominated for the Research
Excellence Award, have decided not to make an award.
The Award is given in recognition of an Artificial
Intelligence scientist who has carried out a program of research of
consistently high quality yielding several substantial results. The
first recipient of this award was John McCarthy in 1985. In the
opinion of the Awards Committee none of the nominated candidates
reached the high standard required. Several members of the Committee
afterwards suggested candidates that, in their opinion, did reach the
required standard, but who had not been nominated.
Nominations for the Award were invited from all in the
artificial intelligence international community. The Award Committee
was the union of the Programme, Conference and Advisory Committees of
IJCAI-87 and the Board of Trustees of IJCAII, with nominees excluded.
It is the sincere hope of all the Committee that, in future
years, a greater effort will be made by the artificial intelligence
community to nominate suitable candidates.

Subject: Conference - Volunteers for AAAI-87
ANNOUNCEMENT:
Student Volunteers Needed for
Artificial Intelligence Conference
AAAI-87
AAAI-87 (American Association on Artificial Intelligence) will
be held July 13-17, 1987 in beautiful Seattle, Washington.
Student volunteers are needed to help with local arrangements
and staffing of the conference. To be eligible for a Volunteer
position, an individual must be an undergraduate or graduate
student in any field at any college or university.
This is an excellent opportunity for students to participate in
the conference. Volunteers receive FREE registration at AAAI-87,
conference proceedings, "STAFF" T-shirt, and are invited to the
volunteer party. More importantly, by participating as a volunteer,
you become more involved and meet students and researchers with
similar interests.
Volunteer responsibilities are varied, including conference
preparation, registration, staffing of sessions and tutorials
and organizational tasks. Each volunteer will be assigned
twelve (12) hours.
If you are interested in participating in AAAI-87 as a Student
Volunteer, apply by sending the following information:
Name
Electronic Mail Address
USMail Address
Telephone Number(s)
Dates Available
Student Affiliation
Advisor's Name
to:
feifer@locus.ucla.edu
or

Thanks, and I hope you join us this year!
