Pednault Electrical Engineering Thursday, July 18, 2:15pm Margaret Jacks Hall, Room 146 Planning problems have the following form: given a set of goals, a set of allowable actions and a description of the current state of the world, find a sequence of actions that will transform the world from its current state to a state in which all of the goals are satisfied. This talk is a presentation of my thesis research which examines the question of how to solve planning problems automatically. The question of plan synthesis will be addressed from a rigorous, mathematical standpoint in contrast to the informal and highly experimental treatments found in most previous works. By introducing mathematical rigor, it has been possible to unify many existing ideas in automatic planning, showing how they arise from first principles and how they may be applied to solve a much broader class of problems than had previously been considered. In addition, some entirely new ideas have been developed and a number of theorems have been proved that further our understanding of the synthesis problem. The talk will concentrate on my techniques for plan synthesis with only a brief summary of the other contributions of my research. A mathematical framework for studying planning problems will be introduced and a number of theorems will be presented that form the basis for the synthesis techniques. These theorems will then be combined with a least-commitment search strategy to obtain a solution method that unifies and generalizes means-ends analysis, opportunistic planning, goal protection, goal regression, constraint posting/propagation, hierarchical planning and nonlinear planning. ------------------------------ Date: Mon 8 Jul 85 15:30:17-PDT From: David Beech <BEECH@SU-SCORE.ARPA> Subject: Seminar - An Object Model of Information (SU) The first Database Seminar of the summer quarter will be this Friday, 12th July, at 3:15 in MJH 352. For information, please contact Beech@Score or call 497-9118. TOWARDS AN OBJECT MODEL OF THE REPRESENTATION AND USE OF INFORMATION David Beech Stanford CIS and HP Laboratories Future general-purpose information systems will need to deal with a wide range of information, and offer flexible access to it, if they are to appeal to the potential millions of non-specialist users. For example, they should process pictures and sounds as naturally as numbers and texts; they should answer questions which require some deduction from the often incomplete information previously given to the system; and they should move towards the support of natural language interfaces, including spoken inputs. An object-oriented model of the representation and use of information is proposed, with the necessary generality for the description and design of such systems. Fundamental concepts including those of agent, object, type, action, formula, process, transaction, predicator and generator are introduced. Recursive functions, predicate calculus, and n-ary relations are brought together in a data abstraction framework, with an emphasis on intensional definition of concepts and their instantiation by means of predicators and generators. ------------------------------ Date: 8 Jul 85 10:19:59 EDT From: Mary.Lou.Maher@CMU-RI-CIVE Subject: Seminar - Expert Systems and Databases (CMU) DESIGN RESEARCH CENTER BI-WEEKLY SEMINAR SERIES Interfacing Expert Systems and Databases for Structural Engineering Applications by Craig Howard Wednesday, July 10 at 1:30 pm in the Adamson Wing, Baker Hall ******* Refreshments will be served at 1:15 ******* Artificial intelligence programming techniques, specifically expert systems and knowledge-based systems (KBS), are being applied to a broad range of engineering problems. However, most prototype expert system applications are restricted to limited amounts of data and have no facility for sophisticated data management. As expert systems are integrated into engineering computing systems, the data management capabilities of these systems must be adapted to serve these new components. The presentation describes work underway to develop a flexible interface in which multiple expert systems and multiple design databases communicate as independent, self-descriptive components within an integrated structural engineering computing environment. ------------------------------ Date: 8 Jul 85 13:17:54 EDT From: Jeanne.Bennardo@CMU-RI-ISL1 Subject: Seminar - Expert System for Grease Selection (CMU) Intelligent Systems Lab Seminar Topic: Presentation of Grease Project Speaker: Dr. Peter Spirtes Place: DH3313 Date: Wednesday, July 10 Time: 10:00am - 11:00am The Grease project is an expert system that is intended to aid in the choice or design of a proper cutting fluid for a metal machining operation. It is currently under development at the Intelligent Systems Lab in cooperation with Gulf Oil Company. Cutting fluids can extend tool life and improve finish by providing lubrication and cooling, and by preventing the welding of the metal being machined to the machining tool. The goal is to find a cutting fluid which will make a machining operation as economical as possible by finding the best trade-off between the price of a cutting fluid and the amount that it extends tool life. ------------------------------ Date: Wed, 3 Jul 85 17:10:09 pdt From: Bill Havens <havens%ubc.csnet@csnet-relay.arpa> Subject: Conference - Canadian AI Conference C A L L F O R P A P E R S Canadian Artificial Intelligence Conference C S C S I - 8 6 Montreal, Canada May 21 - 23, 1986 Sponsored by the Canadian Society for Computational Studies of Intelligence The Sixth National Conference of the CSCSI invites sub- mission of theoretical and applied research papers in all areas of Artificial Intelligence research, particularly those listed below: o Knowledge Representation o Computer Vision o Natural Language Understanding o Expert Systems and Applications o Logic Programming and Formal Reasoning o Robotics o Planning, Problem Solving and Learning o Cognitive Science o Social Aspects of AI o AI Architecture, Languages and Tools All submissions will be fully refereed by the program committee.
