Subject: Seminar - Acquiring Control Knowledge in BB1 (SU)
SIGLUNCH
DATE: Friday, May 24, 1985
LOCATION: Braun Auditorium, Mudd/Chemistry Bldg.
TIME: 12:05
SPEAKER: Mike Hewett

TITLE: MARCK: A Module for Acquiring and Refining
Control Knowledge in BB1
MARCK is the first step in exploiting the capabilities for
knowledge acquisition and learning within the BB1 blackboard
architecture. MARCK automates the role of a BB1 knowledge
engineer by assisting the expert with defining, formulating, and
integrating new control knowledge into a knowledge base during
a problem-solving session.
While running a system in BB1, an expert may take an action
which indicates that some piece of control knowledge is missing.
MARCK uses its knowledge of the control architecture in BB1 to
guide the expert toward identifying the missing knowledge. It
then uses a set of data analysis routines and a library of generic
heuristic forms to postulate some applicable control heuristics.
Although MARCK has no knowledge of the domain, it can generate
domain-dependent control knowledge. MARCK communicates to the
expert through a translator which converts heuristic forms and
LISP code into English sentences.
MARCK is currently being used in the PROTEAN project at KSL
and several examples will be presented where MARCK has formulated
important and useful pieces of control knowledge.

12 noon TINLunch
Ventura Hall ``Computers and Emotion''
Conference Room Discussion led by Helen Nissenbaum
Emotion is an integral part of human consciousness. Yet common
practice in AI takes its ideal to be an intelligent, goal-driven agent
entirely devoid of passion. The assumption behind the practice is
that emotionless intellect is possible, and that a purely cognitive
agent is a valid abstraction from the total human individual. The
TINLunch, inspired by a TINLunch held October 13, 1981, titled ``Will
Robots Need Emotions?'', probes the AI assumption. I offer the
following as starting points for the discussion:
- What would it take to have a computer with emotions?
- Why worry about this? A passionless automaton is fully rational
and far better off for not having emotions. (Too bad we humans suffer
this affliction.)
- These are idle speculations. A sufficiently complex robot, that
could truly be said to understand and be goal-driven, will, of
necessity, have emotion, no matter what the intentions of its
creators.
Background readings are excerpts from Hume's ``Of the Passions'',
Jerome Shaffer's ``An Assessment of Emotion'' and TINLunch Outline
``Will Robots Need Emotions?'' by A. Archbold and N. Haas.

10:30 A.M. KNOWLEDGE, BELIEFS, TIME AND MORE PUZZLES
Cafe. A In "Knowledge, Common Knowledge and Related Puzzles,"
PODC 84, a logical system for formalizing reasoning
about knowledge and time was proposed. Ongoing
research around this system will be described and
touch on subjects such as: restrictions on how one
may acquire knowledge, surprises, beliefs, and
knowledge about time.

FUNCTIONAL PROGRAMMING AND THE LOGICAL VARIABLE
Gary Lindstrom
Department of Computer Science
University of Utah
Salt Lake City, Utah 84112
Logic programming offers a variety of computational effects which go beyond
those customarily found in functional programming languages. Among these
effects is the notion of the "logical variable," i.e. a value determined by the
intersection of constraints, rather than by direct binding. We argue that this
concept is "separable" from logic programming, and can sensibly be incorporated
into existing functional languages. Moreover, this extension appears to
significantly widen the range of problems which can efficiently be addressed in
function form, albeit at some loss of conceptual purity. In particular, a form
of side-effects arises under this extension, since a function invocation can
exert constraints on variables shared with other function invocations.
Nevertheless, we demonstrate that determinacy can be retained, even under
parallel execution. The graph reduction language FGL is used for this
demonstration, by being extended to a language FGL+LV permitting formal
parameter expressions, with variables occurring therein bound by unification.
The determinacy argument is based on a novel dataflow-like rendering of
unification. In addition the complete partial order employed in this
proof is unusual in its explicit representation of demand, a necessity
given the "benign" side-effects that arise. An implementation
technique is suggested, suitable for reduction architectures.

Subject: Workshop - Applications of Expert Systems
The U. S. Army Research Office is sponsoring a Summer Workshop on
Application of Expert Systems. The workshop will be held on July 16,18
1985 at the Hyatt Regency Crystal City, Arlington, Virginia.
The workshops objective is to assess the application of expert systems
to military applications and to identify the state-of-the-art and research
needs. Particular emphasis shall be given to diagnostic and automatic
test applications.
The four main topics for discussion in the working sessions are:
1. Preventive maintenance -- Prognostics
2. Diagnostic maintenance
3. Automatic logistics planning
4. Automatic training
The keynote speaker for the workshop will Lieutenant General Robert Moore
Deputy Commander for Research Development and Acquisition - US Army Materiel
Command.
The workshop attendance is limited to 50 participants from the US Army
industry, and academia. The program will consist of invited and
submitted papers. A 200 word abstract must be submitted to the program
committee prior to June 15, 1985 for consideration.
Abstracts should be sent to Dr. Johannes of the Program committee.
The author will be notified of acceptance of the paper and particpation
by June 21, 1985.
Accepted papers will published in the proceedings of the conference
and will be allocted a maximum of five pages.
