Learning and reasoning are both aspects of what is considered to be intelligence. Their studies within AI have been separated historically, learning being the topic of machine learning and neural networks, and reasoning falling under classical (or symbolic) AI. However, learning and reasoning are in many ways interdependent. This paper discusses the nature of some of these interdependencies and proposes a general framework called FLARE, that combines inductive learning using prior knowledge together with reasoning in a propositional setting. Several examples that test the framework are presented, including classical induction, many important reasoning protocols and two simple expert systems.

A Review of Qualitative Reasoning: Modeling and Simulation with Incomplete Knowledge

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 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. It also presents the results of the competition and related events and provides suggestions for the direction of future exhibitions.

The 1994 AAAI Robot-Building Laboratory (RBL-94) was held during the Twelfth National Conference on Artificial Intelligence. The primary goal of RBL-94 was to provide those with little or no robotics experience the opportunity to acquire practical experience in a few days. Thirty persons, with backgrounds ranging from university professors to practitioners from industry, participated in the three-part lab.

For example, why have Minton have a chapter on the modeling However, many application AIbased approaches garnered success and analysis of the effectiveness issues were not emphasized by the in these particular applications? How of this paradigm, and Miyashita technologists (such as how to present have ORbased approaches done in and Sycara describe a case-based bottleneck information to the user or these same applications? Why are AIbased approach to repair selection.

Georgia Tech's approach differed from other The contest required competing by the robots to collect trash; (3) cooperative robot entries to clean up a messy office behaviors provide for cooperation between strewn with trash. Wads of paper, Styrofoam robots; (4) temporal sequencing coordinates coffee cups, and soda cans were placed by transitions between distinct operating states judges throughout the contest arena along for each robot and achieves the desired goal with wastebaskets, where they hoped the state; (5) fast vision locates soda cans, wastebaskets, robots would deposit the trash. During competitive robot hardware and specifies behavioral states trials, each robot was to gather and throw and transitions between them; and (6) a realtime away as much trash as possible in 10 minutes. The task proved processing are outlined in the next section. The article closes trash in a wastebasket. Unfortunately, the with strategies used and lessons learned at the computational overhead was so great that competition. If a robot was The 10-pound robots were built using off-theshelf near an item of trash or a wastebasket, it components at a cost of approximately could signal its intent to pick up or throw $1700 each.

In its early stages, the field of AI had as its main goal the invention of computer programs having the general problem-solving abilities of humans. Along the way, a major shift of emphasis developed from general-purpose programs toward performance programs, ones whose competence was highly specialized and limited to particular areas of expertise. In this article, I claim that AI is now at the beginning of another transition, one that will reinvigorate efforts to build programs of general, humanlike competence. These programs will use specialized performance programs as tools, much like humans do.

How can an artificial agent react to a situation after performing the correct amount of thinking? My Ph.D. dissertation (Zilberstein 1993)2 presents a theoretical framework and a programming paradigm that provide an answer to this question.
