Abductive Explanation-Based Learning: A Solution to the Multiple Inconsistent Explanation Problem

by William W. Cohen - Blackwell Guide to the Philosophy of Information and Computing, Basil , 1994
"... One problem which frequently surfaces when applying explanation-based learning (EBL) to imperfect theories is the multiple inconsistent explanation problem. The multiple inconsistent explanation problem occurs when a domain theory produces multiple explanations for a training instance, only some of ..."

One problem which frequently surfaces when applying explanation-based learning (EBL) to imperfect theories is the multiple inconsistent explanation problem. The multiple inconsistent explanation problem occurs when a domain theory produces multiple explanations for a training instance, only some

Globally Consistent Range Scan Alignment for Environment Mapping

by F. Lu, E. Milios - AUTONOMOUS ROBOTS , 1997
"... A robot exploring an unknown environmentmay need to build a world model from sensor measurements. In order to integrate all the frames of sensor data, it is essential to align the data properly. An incremental approach has been typically used in the past, in which each local frame of data is alig ..."

is aligned to a cumulative global model, and then merged to the model. Because different parts of the model are updated independently while there are errors in the registration, such an approachmay result in an inconsistent model. In this paper, we study the problem of consistent registration of multiple

Bank Runs, Deposit Insurance, and Liquidity

by Douglas W. Diamond, Philip H. Dybvig - Journal of Political Economy , 2000
"... This article develops a model which shows that bank deposit contracts can provide allocations superior to those of exchange markets, offering an explanation of how banks subject to runs can attract deposits. Investors face privately observed risks which lead to a demand for liquidity. Traditional ..."
Abstract - Cited by 1245 (15 self) - Add to MetaCart
. Traditional demand deposit contracts which provide liquidity have multiple equilibria, one of which is a bank run. Bank runs in the model cause real economic damage, rather than simply reflecting other problems. Contracts which can prevent runs are studied, and the analysis shows

The Merge/Purge Problem for Large Databases

by Mauricio Hernandez, Mauricio A. Hern'andez, Salvatore Stolfo - In Proceedings of the 1995 ACM SIGMOD , 1995
"... Many commercial organizations routinely gather large numbers of databases for various marketing and business analysis functions. The task is to correlate information from different databases by identifying distinct individuals that appear in a number of different databases typically in an inconsiste ..."
Abstract - Cited by 359 (3 self) - Add to MetaCart
in an inconsistent and often incorrect fashion. The problem we study here is the task of merging data from multiple sources in as efficient manner as possible, while maximizing the accuracy of the result. We call this the merge/purge problem. In this paper we detail the sorted neighborhood method that is used

Inconsistency Handling in Multi-Perspective Specifications

by A. Finkelstein, D. Gabbay, A. Hunter, J. Kramer, B. Nuseibeh - IEEE TRANSACTIONS ON SOFTWARE ENGINEERING , 1994
"... The development of most large and complex systems necessarily involves many people - each with their own perspectives on the system defined by their knowledge, responsibilities, and commitments. To address this we have advocated distributed development of specifications from multiple perspectives. ..."
Abstract - Cited by 239 (44 self) - Add to MetaCart
. However, this leads to problems of identifying and handling inconsistencies between such perspectives. Maintaining absolute consistency is not always possible. Often this is not even desirable since this can unnecessarily constrain the development process, and can lead to the loss of important information

Doing It Now or Later

by Ted O'Donoghue, Matthew Rabin , 1996
"... Though economists assume that intertemporal preferences are time-consistent, evidence suggests that a person 's relative preference for well-being at an earlier moment over a later moment increases as the earlier moment gets closer. We explore the behavioral and welfare implications of such tim ..."
Abstract - Cited by 326 (9 self) - Add to MetaCart
. These behavioral results have corresponding welfare implications: With salient costs, mild self-control problems can severely damage a person only if she is naive, while with salient rewards mild self-control problems can severely damage a person only if she is sophisticated. We also consider a multiple

Parts Of Recognition

by D.D. Hoffman, Whitman Richards - COGNITION , 1983
"... A complete theory of object recognition is an impossibility not simply because of the multiplicity of visual cues we exploit in elegant coordination to identify an object, but primarily because recognition involves fixation of belief, and anything one knows may be relevant. We finesse this obstacle ..."

The PROMPT Suite: Interactive Tools for Ontology Merging and Mapping

by Natalya F. Noy, Mark A. Musen - International Journal of Human-Computer Studies , 2003
"... Researchers in the ontology-design field have developed the content for ontologies in many domain areas. This distributed nature of ontology development has led to a large number of ontologies covering overlapping domains. In order for these ontologies to be reused, they first need to be merged o ..."
Abstract - Cited by 275 (17 self) - Add to MetaCart
-automatic ontology merging: iPrompt is an interactive ontologymerging tool that guides the user through the merging process, presenting him with suggestions for next steps and identifying inconsistencies and potential problems. AnchorPrompt uses a graph structure of ontologies to find correlation between concepts

Using ViewPoints for Inconsistency Management

by Steve Easterbrook, Bashar Nuseibeh - SOFTWARE ENGINEERING JOURNAL , 1996
"... Large-scale software development is an evolutionary process. In an evolving specification, multiple development participants often hold multiple, inconsistent views on the system being developed, and considerable effort is spent handling recurrent inconsistencies. Detecting and resolving inconsisten ..."

On the decidability and complexity of query answering over inconsistent and incomplete databases

by Andrea Calì, Domenico Lembo, Riccardo Rosati - In Proc. of PODS 2003 , 2003
"... In databases with integrity constraints, data may not satisfy the constraints. In this paper, we address the problem of obtaining consistent answers in such a setting, when key and inclusion dependencies are expressed on the database schema. We establish decidability and complexity results for query ..."
Abstract - Cited by 149 (29 self) - Add to MetaCart
obtained in a single database context, such results are directly applicable to data integration, where multiple information sources may provide data that are inconsistent with respect to the global view of the sources. 1.
