IJCAI-95 Workshop on Adaptation and Learning in Multiagent Systems
The goal of the Workshop on Adaptation and Learning in Multiagent Systems was to focus on research that addresses unique requirements for agents learning and adapting to work in the presence of other agents. Recognizing the applicability and limitations of current machine-learning research as applied to multiagent problems and developing new learning and adaptation mechanisms particularly targeted to this class of problems were the primary research issues that we wanted the authors to address. This article outlines the presentations that were made at the workshop and the success of the workshop in meeting the established goals. Issues that need to be better understood are also presented.
The 1995 Robot Competition and Exhibition
Hinkle, David, Kortenkamp, David, Miller, David
The 1995 Robot Competition and Exhibition was held in Montreal, Canada, in conjunction with the 1995 International Joint Conference on Artificial Intelligence. The competition was designed to demonstrate state-of-the-art autonomous mobile robots, highlighting such tasks as goal-directed navigation, feature detection, object recognition, identification, and physical manipulation as well as effective human-robot communication. The competition consisted of two separate events: (1) Office Delivery and (2) Office Cleanup. The exhibition also consisted of two events: (1) demonstrations of robotics research that was not related to the contest and (2) robotics focused on aiding people who are mobility impaired.
CAIR-2 Intelligent Mobile Robot for Guidance and Delivery
Yang, Hyun S., Chung, Jiyoon, Ryu, Byeong S., Lee, Juho
CAIR-2 from the Korea Advanced Institute of Science and Technology (KAIST) placed first in the Office Delivery event at the 1995 Robot Competition and Exhibition, held in conjunction with the Fourteenth International Joint Conference on Artificial Intelligence (IJCAI-95). CAIR-2 is a totally self-contained and autonomous mobile robot, and its control architecture incorporates both behavior-based and planner-based approaches. In this article, we present a short description of CAIR-2's hardware, system and control architecture, realtime vision, and speech recognizer.
LOLA Probabilistic Navigation for Topological Maps
Gutierrez-Osuna, Ricardo, Luo, Ren C.
LOLA's entry in the Office Delivery event of the 1995 Robot Competition and Exhibition, held in conjunction with the Fourteenth International Joint Conference on Artificial Intelligence, was the culmination of a three-month design and implementation period for an indoor navigation system for topological maps. This article describes the major components of the robot's navigation architecture. It also summarizes the experiences and lessons learned from the competition.
The 1995 Fall Symposia Series
Cohn, David, Lewis, David, Aha, David W., Burke, Robin, Srihari, Rohini K., Horswill, Ian, Buvac, Sasa, Siegel, Eric V., Fehling, Michael
The Association for the Advancement of Artificial Intelligence (AAAI) held its 1995 Fall Symposia Series on 10 to 12 November in Cambridge, Massachusetts. This article contains summaries of the eight symposia that were conducted: (1) Active Learning; (2) Adaptation of Knowledge for Reuse; (3) AI Applications in Knowledge Navigation and Retrieval; (4) Computational Models for Integrating Language and Vision; (5) Embodied Language and Action Symposium; (6) Formalizing Context; (7) Genetic Programming; and (8) Rational Agency: Concepts, Theories, Models, and Applications.
Development of Self-Maintenance Photocopiers
Shimomura, Yoshiki, Tanigawa, Sadao, Umeda, Yasushi, Tomiyama, Tetsuo
The traditional reliability design methods are imperfect because the designed systems aim at fewer faults, but once a fault happens, the systems might hard fail. Regarding the repair-executing capability, control-type repair strategy was followed. However, the prototype revealed the following problems when its reasoning system was used with a commercial product as embedded software: (1) poor performance of the reasoning system, (2) system size that was too large, (3) low adaptability to environmental changes, and (4) roughness of qualitative repair operations. To solve these problems, we proposed new reasoning method based on virtual cases and fuzzy qualitative values.
AGETS MBR An Application of Model-Based Reasoning to Gas Turbine Diagnostics
Winston, Howard A., Clark, Robert T., Buchina, Gene
A common difficulty in diagnosing failures within Pratt & Whitney's F100-PW-100/200 gas turbine engine occurs when a fault in one part of a system -- comprising an engine, an airframe, a test cell, and automated ground engine test set (AGETS) equipment -- is manifested as an out-of-bound parameter elsewhere in the system. However, because the self-diagnostics only test the specified local parameter, it will pass, leaving only the operators' experience and traditional fault-isolation manuals to locate the source of the problem in another part of the system. This article describes a diagnostic tool (that is, AGETS MBR), designed to overcome this problem by isolating failures using an overall system troubleshooting approach. AGETS MBR was developed jointly by personnel at Pratt & Whitney and United Technologies Research Center using an AI tool called the qualitative reasoning system (QRS).
Financial Crimes Enforcement Network AI System (FAIS) Identifying Potential Money Laundering from Reports of Large Cash Transactions
Senator, Ted E., Goldberg, Henry G., Wooton, Jerry, Cottini, Matthew A., Klinger, Christina D., Llamas, Winston M., Marrone, Michael P., Wong, Raphael W. H.
The Financial Crimes Enforcement Network (FIN-CEN) AI system (FAIS) links and evaluates reports of large cash transactions to identify potential money laundering. The objective of FAIS is to discover previously unknown, potentially high-value leads for possible investigation. FAIS consists of an underlying database (that functions as a black-board), a graphic user interface, and several preprocessing and analysis modules. FAIS has been in operation at FINCEN since March 1993; a dedicated group of analysts process approximately 200,000 transactions a week, during which time over 400 investigative support reports corresponding to over $1 billion in potential laundered funds were developed.
DAS: Intelligent Scheduling Systems for Shipbuilding
Lee, Jae Kyu, Lee, Kyoung Jun, Hong, June Seok, Kim, Wooju, Kim, Eun Young, Choi, Soo Yeoul, Kim, Ho Dong, Yang, Ok Ryul, Choi, Hyung Rim
Daewoo Shipbuilding Company, one of the largest shipbuilders in the world, has experienced great deal of trouble with the planning and scheduling of its production process. To solve the problems, from 1991 to 1993, Korea Advanced Institute of Science and Technology (KAIST) and Daewoo jointly conducted the Daewoo Shipbuilding Scheduling (das) Project. To integrate the scheduling expert systems for shipbuilding, we used a hierarchical scheduling architecture. To automate the dynamic spatial layout of objects in various areas of the shipyard, we developed spatial scheduling expert systems.
