TIME: 12:05 SPEAKER: Mike Hewett Knowledge Systems Laboratory 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. ------------------------------ Date: Wed 22 May 85 17:10:28-PDT From: Emma Pease <Emma@SU-CSLI.ARPA> Subject: Seminar - Computers and Emotion (CSLI) [Excerpted from the CSLI Newsletter by Laws@SRI-AI.] *NEXT* THURSDAY, May 30, 1985 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. --Helen Nissenbaum ------------------------------ Date: Wed, 22 May 85 18:36:12 PDT From: IBM San Jose Research Laboratory Calendar <calendar%ibm-sj.csnet@csnet-relay.arpa> Subject: Seminar - Knowledge, Beliefs, Time and More Puzzles (IBM-SJ) IBM San Jose Research Lab 5600 Cottle Road San Jose, CA 95193 Wed., May 29 Computer Science Seminar 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. Prof. D. L.

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. ------------------------------ Date: Wed, 22 May 85 11:49:55 EDT From: johannes@BRL.ARPA 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. Program Committee Dr. J. D. Johannes Dr. C. R. Green Dr. W. M.
