mitcs Historically and philosophically, CBR exists as a reaction to rule-based reasoning: In CBR, the emphasis is on the case, not the rule. Case-based reasoning is usually associated with work that has been called "scruffy": work that aims at the design of software systems and that takes its main themes and inspiration from psychology (e.g., Eleanor Rosch). Case-based reasoning moved to the center of AI when the logical issues of postponing rule-formation were separated from the psychological issues of stuctural ANALOGY. www.cs.wustl.edu /~loui/mitcs   (1432 words)

Case-based Reasoning Case-based knowledge is evident in precedence based reasoning (such as in tax law or accounting) and is useful when little evidence is available or the information is incomplete. This type of reasoning is based on the premise that human beings learn and solve complex problems by using analogical or experiential reasoning. If no reasonably appropriate prior case is found, then the current case and its human created solution can be added to the case base thus allowing the system to learn. www.geocities.com /expertsystems_2000/casebased.htm   (473 words)

Case based reasoning Case-based reasoning (CBR) is an intelligent-systems method that enables information managers to increase efficiency and reduce cost by substantially automating processes such as diagnosis, scheduling and design. A case-based reasoner works by matching new problems to "cases" from a historical database and then adapting successful solutions from the past to current situations. A collection of cases is called a case base and makes it possible to support for instance decision support for a specific part of a domain. www.rossena.nl /caseb.htm   (256 words)

Case-Based Reasoning Case-based reasoning builds on the idea that human expertise is not composed of formal structures like rules, but of experience: a human expert reasons by relating a new problem to previous ones.Case-based reasoning now amounts to reasoning by comparing a new problem with a set of stored previous problems with their solution. A major problem in case-based reasoning however, resides in the retrieval of cases that are sufficiently similar to a new problem at hand. Case-based reasoning differs from traditional rule-based systems in the sense that knowledge is not represented in rules but in examples. www.tenback.org /Robert/cbr.html   (490 words)

Case-Based Reasoning: A Review (published in The Knowledge Engineering Review, Vol.9 No.4, 1994) Case storage is an important aspect in designing efficient CBR systems in that, it should reflect the conceptual view of what is represented in the case and take into account the indices that characterise the case. The goal of CBR systems is thus to be reminded of similar cases when faced with a new problem and to retrieve those cases in order to help the user solve the new problem in a fashion similar to the way it was solved for a closely matching situation. Cases can be represented in a variety of forms using the full range of AI representational formalisms including frames, objects, predicates, semantic nets and rules - the frame/object representation currently being used by the majority of CBR software. www.ai-cbr.org /classroom/cbr-review.html   (14313 words)

Case Based Reasoning Over the last eight years, we have been working on the problem of case-based reasoning (CBR) for medical diagnosis. Still, it is clear that CBR has not reached its potential to effectively handle the case material and work in concert with a model-based program. Through a succession of research projects, we developed a system that used physiologic causes to match findings in cases, evaluated the system on 240 cases, and developed a system that divides cases and memory based on the diagnostic units in the case. groups.csail.mit.edu /medg/projects/cbr.html   (148 words)

dddddd In this later case, disjunctive metric point-based constraints give rise to a Temporal Constraint Satisfaction Problem (TCSP) (Dechter et al., 1991). These tasks are pending issues in the temporal reasoning area, as well as important features to facilitate modeling of relevant problems in this area (including planning, scheduling, causal or hypothetical reasoning, etc.). This temporal model is composed of a labeled temporal algebra and its reasoning algorithms. www.cs.cmu.edu /afs/cs/project/jair/pub/volume12/barber00a-html/Barber.html   (291 words)

The principles and Art of Cure by Homoeopathy by HERBERT A. ROBERTS, M.D. The principles involved are the same: the examination of the patient, or the record of the proving; the analysis and evaluation of the symptoms in each case; the selection of the remedy; all these are conducted under the rules and in an orderly method based upon inductive reasoning. In other words, he was early trained in inductive reasoning, and he was able to scientifically construct hitherto unknown principles in the case of the sick. This hypothesis, a process of inductive reasoning, proved to be a triumph through the discovery of scientific principles based on natural laws. www.homeoint.org /books4/roberts/chapter02.htm   (3942 words)

Michael Kaess @ College of Computing, Georgia Tech The present method extends the case-based reasoning module by making it capable of learning new and optimizing the existing cases where each case is a set of behavioral parameters. It is based on our previous work on a behavior-based robotic system that also employed spatio-temporal case-based reasoning [3] in the selection of behavioral parameters but was not capable of learning new parameterizations. The goal of this research is not only to automatically optimize the performance of the robot but also to avoid the manual configuration of behavioral parameters and the initial configuration of a case library, both of which require the user to possess good knowledge of robot behavior and the performance of numerous experiments. www.cc.gatech.edu /~kaess/likhachev02icra.html   (3942 words)

fp Defeasible reasoning and case-based reasoning are used to identify exceptions and derivation of acceptable exception handlers. An exception handling mechanism based on defeasible reasoning and case-based reasoning is used to handle exceptions that might result in creations, deletions or modifications of workflow types and starts, terminations or modifications of workflow instances.

Certain Doubts » Defeasible Consequences I take it that the point of developing a logic of defeasible consequence is to represent what an ideal agent (an agent not limited by computational ability or resources) should defeasibly believe based on other statements she accepts (and perhaps based on her nondoxastic states as well). If the question is, given a model of defeasible reasoning such and such, where the two disagree, is the actual person mistaken, then, sure, you are correct: the person is mistaken; this follows trivially. Citing that the probability measure is intuitively compelling is not sufficient grounds for regarding its structure (i.e., the mathematical structure of the measure) to be isomorphic to the structure of the notion you wish to model, which, in this case, is defeasible consequence. bengal-ng.missouri.edu /~kvanvigj/certain_doubts/index.php?p=244   (10382 words)

Remembering to Add: Competence-preserving Case-Addition Policies for Case-Base Maintenance - Zhu, Yang (ResearchIndex) Abstract: Case-base maintenance is gaining increasing recognition in research and the practical applications of case-based reasoning (CBR). In their work, Smyth and Keane advocated a case deletion policy, whereby the cases in a case base are classified and deleted based on their coverage potential and adaptation power. and thereby case competence [15] are modeling the competence of a case base. citeseer.ist.psu.edu /164777.html   (10382 words)

eBay Inc. v. Bidder's Edge Inc. The reasoning in these cases appears to be that a defendant who builds a business model based upon a clear violation of the property rights of the plaintiff cannot defeat a preliminary injunction by claiming the business will be harmed if the defendant is forced to respect those property rights. In order to prevail on a claim for trespass based on accessing a computer system, the plaintiff must establish: (1) defendant intentionally and without authorization interfered with plaintiff's possessory interest in the computer system; and (2) defendant's unauthorized use proximately resulted in damage to plaintiff. Murray, 415 U.S. Nor does eBay appear to have made the required showing that this is the type of extraordinary case in which monetary damages may support equitable relief. pub.bna.com /lw/21200.htm   (10382 words)
