Book Description
Truth maintenance systems (TMS) have been used in several recent problem-solving systems to record justifications for deduced assertions, to track down the assumptions which underlie contradictions when they arise, and to incrementally modify assertional data structures when assumptions are retracted. This report describes a TMS algorithm that is substantially different from previous systems. This algorithm performs deduction in traditional propositional logic in such a way that the premise set from which deduction is being done can be easily manipulated. A novel approach is also taken to the role of a TMS in larger deductive systems. In this approach the TMS performs all propositional deduction in a uniform manner while the larger system is responsible for controlling the instantiation of universally quantified formulae and axiom schemas.

Expert Systems
Author: Cornelius T. Leondes
Publisher: Elsevier
ISBN: 0080531458
Category : Computers
Languages : en
Pages : 2125
Book Description
This six-volume set presents cutting-edge advances and applications of expert systems. Because expert systems combine the expertise of engineers, computer scientists, and computer programmers, each group will benefit from buying this important reference work. An "expert system" is a knowledge-based computer system that emulates the decision-making ability of a human expert. The primary role of the expert system is to perform appropriate functions under the close supervision of the human, whose work is supported by that expert system. In the reverse, this same expert system can monitor and double check the human in the performance of a task. Human-computer interaction in our highly complex world requires the development of a wide array of expert systems. Expert systems techniques and applications are presented for a diverse array of topics including Experimental design and decision support The integration of machine learning with knowledge acquisition for the design of expert systems Process planning in design and manufacturing systems and process control applications Knowledge discovery in large-scale knowledge bases Robotic systems Geograhphic information systems Image analysis, recognition and interpretation Cellular automata methods for pattern recognition Real-time fault tolerant control systems CAD-based vision systems in pattern matching processes Financial systems Agricultural applications Medical diagnosis

Knowledge Representation
Author: T.J.M. Bench-Capon
Publisher: Elsevier
ISBN: 1483297101
Category : Computers
Languages : en
Pages : 236
Book Description
Although many texts exist offering an introduction to artificial intelligence (AI), this book is unique in that it places an emphasis on knowledge representation (KR) concepts. It includes small-scale implementations in PROLOG to illustrate the major KR paradigms and their developments.****back cover copy:**Knowledge representation is at the heart of the artificial intelligence enterprise: anyone writing a program which seeks to work by encoding and manipulating knowledge needs to pay attention to the scheme whereby he will represent the knowledge, and to be aware of the consequences of the choices made.****The book's distinctive approach introduces the topic of AI through a study of knowledge representation issues. It assumes a basic knowledge of computing and a familiarity with the principles of elementary formal logic would be advantageous.****Knowledge Representation: An Approach to Artificial Intelligence develops from an introductory consideration of AI, knowledge representation and logic, through search technique to the three central knowledge paradigms: production rules, structured objects, and predicate calculus. The final section of the book illustrates the application of these knowledge representation paradigms through the Prolog Programming language and with an examination of diverse expert systems applications. The book concludes with a look at some advanced issues in knowledge representation.****This text provides an introduction to AI through a study of knowledge representation and each chapter contains exercises for students. Experienced computer scientists and students alike, seeking an introduction to AI and knowledge representations will find this an invaluable text.

Begründungsverwaltung
Author: Herbert Stoyan
Publisher: Springer Science & Business Media
ISBN: 3642733859
Category : Computers
Languages : en
Pages : 161
Book Description
Dieses Buch enthält die schriftlichen Ausarbeitungen von Vorträgen, die am 9. Oktober 1986 auf einem Workshop über Reason Maintenance gehalten worden sind. Der Begriff Begründungsverwaltung als Übersetzung von Reason Maintenance soll die Gleichzeitigkeit der Aspekte der Speicherung und Aufbewahrung der Begründungen und der Erhaltung der Gültigkeit von Aussagen auf Grund der gültigen Begründungen ausdrücken. Reason Maintenance ist eine Fortführung und Verallgemeinerung von Truth Maintenance. Truth-Maintenance-Systeme sind Programmsysteme, die Speicher von Aussagen realisieren, die weitgehend nur auf aussagenlogischer Ebene formalisiert sind. Sie verwalten Aussagenmengen und ihre Bewertungen. Annahmen und einfache Konsequenzen aus ihnen werden in einer Weise aufbewahrt, da€ eine widerspruchsfreie Aussagenmenge zu jedem konkreten Zeitpunkt erkennbar ist. Die Technik, mit der dieses Ziel erreicht wird, besteht in der Repräsentation der Beziehungen zwischen den Aussagen und in der Aufbewahrung der Prämissen, Implikationen und Schlu€regeln, die zur Ableitung einer bestimmten Aussage verwendet worden sind. Der Zweck dieser Systeme ist demnach Konsistenzerhaltung durch Begründungsverwaltung. Die vorliegenden Arbeiten repräsentieren den deutschen Wissensstand auf diesem Teilgebiet der Künstlichen Intelligenz unter Betonung des Ansatzes von de Kleer. Damit führt dieser Band den Leser an wesentliche aktuelle Forschungsergebnisse heran.

Constraint Processing
Author: Rina Dechter
Publisher: Elsevier
ISBN: 0080502954
Category : Computers
Languages : en
Pages : 503
Book Description
Constraint satisfaction is a simple but powerful tool. Constraints identify the impossible and reduce the realm of possibilities to effectively focus on the possible, allowing for a natural declarative formulation of what must be satisfied, without expressing how. The field of constraint reasoning has matured over the last three decades with contributions from a diverse community of researchers in artificial intelligence, databases and programming languages, operations research, management science, and applied mathematics. Today, constraint problems are used to model cognitive tasks in vision, language comprehension, default reasoning, diagnosis, scheduling, temporal and spatial reasoning. In Constraint Processing, Rina Dechter, synthesizes these contributions, along with her own significant work, to provide the first comprehensive examination of the theory that underlies constraint processing algorithms. Throughout, she focuses on fundamental tools and principles, emphasizing the representation and analysis of algorithms. - Examines the basic practical aspects of each topic and then tackles more advanced issues, including current research challenges - Builds the reader's understanding with definitions, examples, theory, algorithms and complexity analysis - Synthesizes three decades of researchers work on constraint processing in AI, databases and programming languages, operations research, management science, and applied mathematics

Principles of Constraint Programming
Author: Krzysztof Apt
Publisher: Cambridge University Press
ISBN: 1139438700
Category : Computers
Languages : en
Pages : 421
Book Description
Constraints are everywhere: most computational problems can be described in terms of restrictions imposed on the set of possible solutions, and constraint programming is a problem-solving technique that works by incorporating those restrictions in a programming environment. It draws on methods from combinatorial optimisation and artificial intelligence, and has been successfully applied in a number of fields from scheduling, computational biology, finance, electrical engineering and operations research through to numerical analysis. This textbook for upper-division students provides a thorough and structured account of the main aspects of constraint programming. The author provides many worked examples that illustrate the usefulness and versatility of this approach to programming, as well as many exercises throughout the book that illustrate techniques, test skills and extend the text. Pointers to current research, extensive historical and bibliographic notes, and a comprehensive list of references will also be valuable to professionals in computer science and artificial intelligence.
