Adaptive controllers for intelligent monitoring

The project we describe here is aimed at assisting out-patients affected by Insulin Dependent Diabetes Mellitus. Our approach exploits the usual scheme of diabetic patients management, based on (i) a periodic evaluation of patients' metabolic control performed by the physician, and (ii) patient-tailored tables for self-adjustments of insulin dosages. Following this scheme we have defined a system built on a two-level architecture. The High Level Module exploits both medical knowledge and clinical information in order to assess an insulin protocol, defined in terms of insulin timing, type, and total amount. The High Level Module exchanges information with the Low Level Module in order to define the control actions to be taken at the low level, as well as to periodically evaluate protocol adequacy on the basis of patient data. The goal of the Low Level Module, whose characteristics can be adaptively modified by the High Level Module, is to suggest the next insulin dosage, depending on the actual blood glucose measurement and a certain pre-defined insulin delivery protocol. The Level Control Module is based on an adaptive controller, consisting of a Fuzzy Set Controller and an ARX (Autoregressive eXogenous input) Model. The scheme here presented may be conveniently viewed in a telemedicine context, in which the low level controller is implemented on a portable device communicating to the high level controller, implemented on a remote computer. A preliminary assessment has been performed, analyzing a data set of 60 patients provided by the American Association of Artificial Intelligence, Artificial Intelligence in Medicine Subgroup, and the implementation of the system is currently in progress.

The 1994 AAAI Robot Competition and Exhibition

The third annual AAAI Robot Competition and Exhibition was held in 1994 during the Twelfth National Conference on Artificial Intelligence in Seattle, Washington. The competition was designed to showcase and compare the state of the art in autonomous indoor mobile robots. The competition featured Office Delivery and Office Cleanup events, which demanded competence in navigation, object recognition, and manipulation. The competition was organized into four parts: (1) a preliminary set of trials, (2) the competition finals, (3) a public robot exhibition, and (4) a forum to discuss technical issues in AI and robotics. Over 15 robots participated in the competition and exhibition. This article describes the rationale behind the events and the rules for the competition. It also presents the results of the competition and related events and provides suggestions for the direction of future exhibitions.

Book preview: Intelligent MultiMedia Interfaces Edited by Mark T. Maybury (MIT Press)

This collection is an outgrowth of the American Association for Artificial Intelligence (AAAI) Workshop on Intelligent Multimedia Interfaces which took place at Anaheim, California in August of 1991. Multimedia interfaces are computer interfaces that communicate with users using multiple media (e.g., language, graphics, animations, video, non-speech audio) in multiple modalities (e.g., written text versus spoken language). Intelligent multimedia interfaces go beyond traditional hypemedia or hypertext environments and both process input and generate output in an intelligent or knowledge-based manner.

CARMEL Versus FLAKEY A Comparison of Two Winners

■ The University of Michigan’s CARMEL and SRI International’s FLAKEY were the first- and secondplace finishers, respectively, at the 1992 Robot Competition sponsored by the American Association for Artificial Intelligence. The two teams used vastly different approaches in the design of their robots. Many of these differences were for technical reasons, although time constraints, financial resources, and long-term research objectives also played a part. This article gives a technical comparison of CARMEL and FLAKEY, focusing on design issues that were not directly reflected in the scoring criteria.

Reasoning with Diagrammatic Representations: A Report on the Spring Symposium

We report on the spring 1992 symposium on diagrammatic representations in reasoning and problem solving sponsored by the Association for the Advancement of Artificial Intelligence. The symposium brought together psychologists, computer scientists, and philosophers to discuss a range of issues covering both externally represented diagrams and mental images and both psychology -- and AI-related issues. In this article, we develop a framework for thinking about the issues that were the focus of the symposium as well as report on the discussions that took place. We anticipate that traditional symbolic representations will increasingly be combined with iconic representations in future AI research and technology and that this symposium is simply the first of many that will be devoted to this topic.

The Gardens of Learning: A Vision for AI

The field of AI is directed at the fundamental problem of how the mind works; its approach, among other things, is to try to simulate its working -- in bits and pieces. History shows us that mankind has been trying to do this for certainly hundreds of years, but the blooming of current computer technology has sparked an explosion in the research we can now do. The center of AI is the wonderful capacity we call learning, which the field is paying increasing attention to. Learning is difficult and easy, complicated and simple, and most research doesn't look at many aspects of its complexity. However, we in the AI field are starting. Let us now celebrate the efforts of our forebears and rejoice in our own efforts, so that our successors can thrive in their research. This article is the substance, edited and adapted, of the keynote address given at the 1992 annual meeting of the Association for the Advancement of Artificial Intelligence on 14 July in San Jose, California.
