Making Electronic Mail More Intelligent
October 31, 1985
Thomas Malone, MIT
Kenneth Mayers, Digital Equipment Corporation
Electronic messaging has become a familiar feature of the
office environment and a key element in office automation
strategy for many organizations. As these systems spread, many
issues must be dealt with, such as accomodating evolving user
requirements, responding to rapid expansion, controlling junk
mail, and incorporating alternative technologies. One of the
central challenges is how to enhance messaging features so that
users are not swamped by information overload.
This forum will present the experience of Digital Equipment
Corporation, one of the pioneering users of electronic mail, and
will describe some recent innovative research at MIT which uses
artificial intelligence technology to improve the user's ability
to sort incoming messages by relevance and urgency and to route
outgoing communications to the most appropriate people within the
organizations.

Subject: Seminar - Connectionist Learning (GTE)
GTE LABORATORIES INC
MACHINE LEARNING SEMINAR
TITLE: Learning by Statistical Cooperation
in Connectionist Networks
SPEAKER: Prof. Andrew G. Barto
University of Massachusetts at Amherst
TIME: 2pm, Wednesday, October 23
PLACE: GTE Laboratories Inc
40 Sylvan Rd
Waltham MA 02254
Since the usual approaches to cooperative computation in networks of
neuron-like computating elements do not assume that network components
have any ``preferences," they do not make substantive contact with game
theoretic concepts, despite their use of some of the same terminology.
In the approach I describe, however, each network component, or adaptive
element, is a self-interested agent that prefers some inputs over others
and ``works" toward obtaining the most highly preferred inputs. I
describe some of our work with an adaptive element that is robust enough
to learn to cooperate with other elements like itself in order to
further its self-interests. It is argued that some of the long-standing
problems concerning adaptation and learning by networks might be
solvable by this form of cooperativity, and computer simulation
experiments are described that show how networks of self-interested
components that are sufficiently robust can solve rather difficult
learning problems. A secondary aim of this talk is to suggest that
beyond what I explicitly illustrate, there is a wealth of ideas from
game theory and allied disciplines such as mathematical economics that
can be of use in thinking about cooperative computation in both nervous
systems and man-made systems.

"From Classical Conditioning to Cognitive Computations"
Richard S. Sutton
GTE Fundamental Research Laboratory
Date: Mon, Oct. 28 Time: 12:00-1:15 Place: Room 100, Jordan Hall
One attractive aspect of connectionist models is their ability to make
contact with a wide range of fields from neuroscience to cognitive
science and AI. In this talk I will review the status of the
"connectionist connection" between such fields and present some of my
own work as an example of a case in which pursuing it has been fruitful.
I will present a sequence of three closely-related connectionist
learning models. The first was presented by Sutton and Barto in 1981 as
a real-time model of classical conditioning consistent with many
behavioral phenomena including blocking, conditioned inhibition, the ISI
dependency, higher-order conditioning, and serial-compound effects. The
second model is the result of changes made to the first in trying to use
it in an AI learning problem. Remarkably, the modified model is not
only very effective on the AI problem, but is also a better match to the
classical conditioning data than the first model. I am currently
working on a third model that is able to reproduce the
animal learning phenomena of latent learning and sensory
preconditioning. The AI goal for this model is to build a system that
can learn about and then reason about its environment. The model shows
promise of being simultaneously very successful as all of 1) a model of
classical conditioning, 2) an aid to AI machine learning systems, and 3)
a model of simple forms of inference and planning.
*****************************************************************************
The CCNJCS^3 was formed in response to a growing interest among
members of the Psychology, Computer Science, and Neuroscience
departments at Stanford in learning about recent advances in the
study of computational approaches to modelling the relationship
between cognition and neuroscience. In addition to organizing
seminars, we also arrange journal club meetings in which graduate
students and post-docs meet to read and discuss current research
articles dealing with: The neural substrates of learning and memory,
computational models of neuronal processes, and the neural bases
of cognitive behavior.

SIGLUNCH will be held at the Chemistry Gazebo at 12:05-1:00 p.m.
Probabilistic Interpretations for MYCIN's Certainty Factors
David Heckerman
I will show that the original definition of certainty factors (CF's)
is inconsistent with the "defining desiderata" of the CF combination
functions. I will then show that if this inconsistency is removed by
redefining CF's in terms of the desiderata then CF's have
probabilistic interpretations. In other words, I will show that
certainty factors are nothing more than transformed probabilistic
quantities. The construction of the interpretation provides insights
into the assumptions made when propagating CF's through an inference
net. For example, it can be shown that all evidence which bears
directly on a hypothesis must be conditionally independent on the
hypothesis and its negation. After presenting the interpretations,
I will discuss several ramifications of the correspondence between
CF's and probabilities.
