Cognitive Computing: Building A Machine That Can Learn From Experience

AITopics Original Links

But University of Wisconsin-Madison research psychiatrist Giulio Tononi, who was recently selected to take part in the creation of a "cognitive computer," says the goal of building a computer as quick and flexible as a small mammalian brain is more daunting than it sounds. Tononi, professor of psychiatry at the UW-Madison School of Medicine and Public Health and an internationally known expert on consciousness, is part of a team of collaborators from top institutions who have been awarded a $4.9 million grant from the Defense Advanced Research Projects Agency (DARPA) for the first phase of DARPA's Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE) project. Tononi and scientists from Columbia University and IBM will work on the "software" for the thinking computer, while nanotechnology and supercomputing experts from Cornell, Stanford and the University of California-Merced will create the "hardware." Dharmendra Modha of IBM is the principal investigator. "Every neuron in the brain knows that something has changed," Tononi explains.


AI Planning: Systems and Techniques

AI Magazine

This article reviews research in the development of plan generation systems. Our goal is to familiarize the reader with some of the important problems that have arisen in the design of planning systems and to discuss some of the many solutions that have been developed in the over 30 years of research in this area. In this article, we broadly cover the major ideas in the field of AI planning and show the direction in which some current research is going. We define some of the terms commonly used in the planning literature, describe some of the basic issues coming from the design of planning systems, and survey results in the area. Because such tasks are virtually never ending, and thus, any finite document must be incomplete, we provide references to connect each idea to the appropriate literature and allow readers access to the work most relevant to their own research or applications.

The need for presenting useful descriptions of problem solving activities has grown with the size and complexity of contemporary AI systems. Simply tracing and explaining the activities that led to a solution is no longer satisfactory. We describe a domain-independent approach for selectively abstracting the chronological history of problem solving activity (a system trace) based upon usersupplied abstraction goals. An important characteristic of our approach is that, given different abstraction goals, abstracted traces with significantly different emphases can be generated from the same original trace. Although we are not concerned here with the generation of an explanation from the abstracted trace, this approach is a useful step towards such an explanation facility.

This paper presents a summary of the invited presentations at the 1999 Florida Artificial Intelligence Research Symposium (FLAIRS) Knowledge Management (KM) track. This track focuses on the effective design and development of state of the art KM applications. The goal of this track is to continue a longterm effort in integrating works that address important issues and current unsolved problems with regard to research in KM, and publicizing the contribution of AI in KM by maintaining contacts and advertising sharable resources (mailing list, archives, Web site, etc.). Furthermore this track attempts to determine what is common in all Knowledge Management domains so that the KM community can further this work. It has been observed that KM Systems underway at most organizations fall into three categories: Educational KM systems, Knowledge repositories, and Problem solving KM systems. State of the art applications in all three categories were presented in this track. The applications presented included an invited presentation on a research tool to elicit and capture the knowledge of experts, a paper on the development of an application to identify experts in the State of Florida State University System, and a paper on the use of Conversational Case-Based Reasoning for Problem-Solving Knowledge Management Systems. Finally, the track included an invited presentation describing KM initiatives at NASA-Kennedy Space Center.


A Problem-Solver for Ma ing Advice Operational

AAAI Conferences

One problem with taking advice arises when the advice is expressed in terms of data or actions unavailable to the advicetaker. For example. in the card game Hearts, the advice "don't lead a suit in which some opponent has no cards left" is nonoperational because players cannot see their opponents' cards.
