The Knowledge-Based Computer System Development Program of India: A Review
Each node has between Joshi), and computational vision (S. Papers were presented by The Department of Electronics, Government under contract with Indian companies. Seven major research and KBCS applications, including expert logic programming (which teaching centers and a number of systems for government administration, seems to be well developed in India), associated institutions are involved expert systems for engineering and reasoning. The level of most presentations are the Center for the Development vision system applications, and was good and of an international of Advanced Computing (Pune), the KBCS applications in and for ancient flavor. The audience was Department of Electronics (New Indian sciences; and language-processing unusually active, initiating discussions Delhi), The Indian Institute of Science technologies, including natural and friendly controversies.
Logical Versus Analogical or Symbolic Versus Connectionist or Neat Versus Scruffy
Engineering and scientific education condition us to expect everything, including intelligence, to have a simple, compact explanation. Accordingly, when people new to AI ask "What's AI all about," they seem to expect an answer that defines AI in terms of a few basic mathematical laws. Today, some researchers who seek a simple, compact explanation hope that systems modeled on neural nets or some other connectionist idea will quickly overtake more traditional systems based on symbol manipulation. Others believe that symbol manipulation, with a history that goes back millennia, remains the only viable approach. Marvin Minsky subscribes to neither of these extremist views. Instead, he argues that AI must use many approaches. AI is not like circuit theory and electromagnetism. There is nothing wonderfully unifying like Kirchhoff's laws are to circuit theory or Maxwell's equations are to electromagnetism. Instead of looking for a "right way," the time has come to build systems out of diverse components, some connectionist and some symbolic, each with its own diverse justification." - Patrick Winston
The Use of Artificial Intelligence by the United States Navy: Case Study of a Failure
This article analyzes an attempt to use computing technology, including AI, to improve the combat readiness of a U.S. Navy aircraft carrier. The method of introducing new technology, as well as the reaction of the organization to the use of the technology, is examined to discern the reasons for the rejection by the carrier's personnel of a technically sophisticated attempt to increase mission capability. This effort to make advanced computing technology, such as expert systems, an integral part of the organizational environment and, thereby, to significantly alter traditional decision-making methods failed for two reasons: (1) the innovation of having users, as opposed to the navy research and development bureaucracy, perform the development function was in conflict with navy operational requirements and routines and (2) the technology itself was either inappropriate or perceived by operational experts to be inappropriate for the tasks of the organization. Finally, this article suggests those obstacles that must be overcome to successfully introduce state-of-the-art computing technology into any organization.
Controlling a Black-Box Simulation of a Spacecraft
Sammut, Claude, Michie, Donald
This article reports on experiments performed using a black-box simulation of a spacecraft. The goal of this research is to learn to control the attitude of an orbiting satellite. The space-craft must be able to operate with minimal human supervision. To this end, we are investigating the possibility of using adaptive controllers for such tasks. Laboratory tests have suggested that rule-based methods can be more robust than systems developed using traditional control theory. The BOXES learning system, which has already met with success in simulated laboratory tasks, is an effective design framework for this new exercise.
