Subject: Seminar - Expert System for Fault Diagnosis (SRI)
Time: Wednesday May 29 at 11:00 am
Location: EJ232
Speaker : Guy A. Boy (NASA-Ames & ONERA, France)
Topic : HORSES
HORSES ( Human - [Orbital Refueling System] - Expert System ) is a
malfunction procedure-oriented diagnosis aid. It takes into account
two types of logic, the functioning logic of the system to be
controlled and the user logic. HORSES will be used to study a
theoretical framework of the situation recognition problem.
As a strategy for research in the use of expert systems for fault
diagnosis this example focuses attention on three interrelated issues;
1) The characterization of the fault diagnosis process with the
current ORS implementation (shuttle orbital refueling system
simulator); 2) Improved understanding of how humans recognize,
diagnose, and respond to system failures; and, 3) A deeper analysis of
the fault diagnosis process concentration a better understanding of
the knowledge and inferences required.

"The temporal logic of probabilistic programs"
In a joint work with S. Shelah, some extensions of the propositional
temporal logic of discrete time were advocated as useful for stating
and proving properties of probabilistic concurrent programs. Deductive
completeness theorems were proved. In a joint work with S. Kraus
corresponding decision procedures were investigated. Recently a system
for describing time and knowledge has been proposed. All those systems
can be characterized as two-dimensional modal logics, i.e. they
involve two essentially orthogonal modalities, one of them being time,
that satisfy some interchange law. The techniques involved in
studying such systems and some open problems will be described.

``An Assumption-Based Truth-Maintenance System''
Johan De Kleer, Xerox PARC, Intelligent Systems Lab.
This paper presents a new view of problem solving motivated by a
new kind of truth maintenance system. Unlike previous truth
maintenance systems which were based on manipulating justifications,
this truth maintenance system is, in addition, based on manipulating
assumption sets. As a consequence it is possible to work effectively
and efficiently with inconsistent information, context switching is
free, and most backtracking (and all retraction) is avoided. These
capabilities motivate a different kind of problem-solving architecture
in which multiple potential solutions are explored simultaneously.
This architecture is particularly well-suited for tasks where a
reasonable fraction of the potential solutions must be explored.

ABSTRACT:
We believe that currently marketed programs leave unexploited much
of the potential of the spreadsheet interface. The purpose of our work
is to obtain suggestions for wider application of this interface by
showing how to obtain its main features as a subset of logic program-
ming.
Our work is based on two observations. The first is that
spreadsheets would already be a useful enhancement to interactive
languages such as APL and BASIC. Although Prolog is also an interactive
language, this interface cannot be used in the same direct way. Hence
our second observation: the usual query mechanism of Prolog does not
provide the kind of interaction this application requires. But it can
be provided by the incremental query, a new query mechanism for Prolog.
The two observations together yield the spreadsheet as a display of
the state of the substitution of an incremental query in Prolog. Recal-
culation of dependent cells is achieved by automatic modification of the
query in response to a new increment that would make it unsolvable
without the modification.

The Personal Computer as a Delivery Vehicle
Gerald R. Barber
Gold Hill Computers
Cambridge, MA
The growing interest in artificial intelligence technologies is
stimulating interest in how the benefits of these technologies
can be delivered on a low cost and low risk basis. This talk
focuses on the elements of a personal computer based delivery
vehicle for artificial intelligence applications.
The combination of a growing market for artificial intelligence
applications and dropping development costs have created a need
for an inexpensive, PC based delivery vehicle. Some desirable
characteristics of a PC delivery vehicle will be discussed
including characteristics of the Golden Common Lisp
implementation, performance, networking, memory needs, and use of
backend machines. A strategy for the implementation of
artificial intelligence technology in a cost effective and
incremental fashion will also be discussed.
ACM GREATER BOSTON CHAPTER SICPLAN
Dear Colleague,
Our June speaker, Gerry Barber, is president of Gold Hill
Computers and the prime mover behind their implementation of
Common Lisp for the IBM/PC. Their product Golden Common Lisp
originated when Gerry spent a post-doc year in France at INRIA
and found himself without adequate access to Lisp processors;
hence a Lisp implementation for the IBM/PC. Prior to that Gerry
studied under Carl Hewitt at MIT's AI Lab, receiving a Ph.D. in
1982. The talk should give a good perspective on where AI
application languages are going and how well they are penetrating
into the everyday world of low cost environments.
Our group customarily meets informally for dinner at Joyce
Chen's restaurant, 390 Rindge Ave., Cambridge at 6:00 P.M. (just
before the meeting). If you wish to come, please call Carolyn
Elson at 661-1840 before the day of the talk - early please.
