Available in PDF, EPUB and Kindle. Book excerpt: This report describes the principal findings and recommendations of a 2-year Rand research project on machine-aided knowledge acquisition and discusses the transfer of expertise from humans to machines, as well as the functions of planning, debugging, knowledge refinement, and autonomous machine learning. The relative advantages of humans and machines in the building of intelligent systems are explained. Background and guidance is provided for policymakers concerned with the research and development of machine-based learning systems. The research method adopted emphasized iterative refinement of knowledge in response to actual experience; i.e., a machine's knowledge was acquired initially from a human who provided enough concepts, constraints, and problem-solving heuristics to define some minimal level of performance. Sixty-two references are listed. (Author/FM)

Download or read book Knowledge Acquisition Selected Research and Commentary written by Sandra Marcus and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: What follows is a sampler of work in knowledge acquisition. It comprises three technical papers and six guest editorials. The technical papers give an in-depth look at some of the important issues and current approaches in knowledge acquisition. The editorials were pro duced by authors who were basically invited to sound off. I've tried to group and order the contributions somewhat coherently. The following annotations emphasize the connections among the separate pieces. Buchanan's editorial starts on the theme of "Can machine learning offer anything to expert systems?" He emphasizes the practical goals of knowledge acquisition and the challenge of aiming for them. Lenat's editorial briefly describes experience in the development of CYC that straddles both fields. He outlines a two-phase development that relies on an engineering approach early on and aims for a crossover to more automated techniques as the size of the knowledge base increases. Bareiss, Porter, and Murray give the first technical paper. It comes from a laboratory of machine learning researchers who have taken an interest in supporting the development of knowledge bases, with an emphasis on how development changes with the growth of the knowledge base. The paper describes two systems. The first, Protos, adjusts the training it expects and the assistance it provides as its knowledge grows. The second, KI, is a system that helps integrate knowledge into an already very large knowledge base.
Download or read book Current Trends in Knowledge Acquisition written by Bob Wielinga and published by IOS Press. This book was released on 1990 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge acquisition has become a major area of artificial intelligence and cognitive science research. The papers in this book show that the area of knowledge acquisition for knowledge-based systems is still a diverse field in which a large number of research topics are being addressed. However, several main themes run through the papers. First, the issues of integrating knowledge from different sources and K.A. tools is a salient topic in many papers. A second major topic in the papers is that of knowledge modelling. Research in knowledge-based systems emphasises the use of generic models of reasoning and its underlying knowledge. An important trend in the area of knowledge modelling aims at the formalisation of knowledge models. Where the field of knowledge acquisition was without tools and techniques years ago, now there is a rapidly growing body of techniques and tools. Apart from the integrated workbenches already mentioned above, several papers in this book present new tools. Although knowledge acquisition and machine learning have been considered as separate subfields of AI, there is a tendency for the two fields to come together. This publication combines machine learning techniques with more conventional knowledge elicitation techniques. A framework is presented in which reasoning, problem solving and learning together form a knowledge intensive system that can acquire knowledge from its own experience.

Download or read book Advice taking and Knowledge Refinement written by Frederick Hayes-Roth and published by . This book was released on 1980 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses skill development as an iterative process that coverts advice into plans and, ultimately, converts these plans into behaviors. An overall model is summarized. While this framework treats learning as a largely domain-independent enterprise, it motivates two caveats. First, we believe every skill is largely domain-dependent. Whatever domain independence exists is attributable to the general skills that underlie initial skill acquisition and subsequent skill improvement. Initial skill acquisition depends on the general and complex advice-taking skills of understanding and knowledge programming. In this paper, we have developed many aspects of the advice-taking process. The second phase of learning also employs numerous and relatively general skills. In this phase, diagnostic and learning rules identify and rectify erroneous bits of knowledge. The second caveat on domain-independence recognizes the important role that domain knowledge plays in diagnosis and refinement. A learner's ability to apply diagnosis and learning rules will also depend on his or her familiarity with and expertise in the problem domain. Although these heuristic and learning rules are domain-independent, to apply these rules a learner must be able to reason deductively about and with the entailments of his or her domain knowledge.

Download or read book Automating Knowledge Acquisition for Expert Systems written by Sandra Marcus and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: In June of 1983, our expert systems research group at Carnegie Mellon University began to work actively on automating knowledge acquisition for expert systems. In the last five years, we have developed several tools under the pressure and influence of building expert systems for business and industry. These tools include the five described in chapters 2 through 6 - MORE, MOLE, SALT, KNACK and SIZZLE. One experiment, conducted jointly by developers at Digital Equipment Corporation, the Soar research group at Carnegie Mellon, and members of our group, explored automation of knowledge acquisition and code development for XCON (also known as R1), a production-level expert system for configuring DEC computer systems. This work influenced the development of RIME, a programming methodology developed at Digital which is the subject of chapter 7. This book describes the principles that guided our work, looks in detail at the design and operation of each tool or methodology, and reports some lessons learned from the enterprise. of the work, brought out in the introductory chapter, is A common theme that much power can be gained by understanding the roles that domain knowledge plays in problem solving. Each tool can exploit such an understanding because it focuses on a well defined problem-solving method used by the expert systems it builds. Each tool chapter describes the basic problem-solving method assumed by the tool and the leverage provided by committing to the method.

Download or read book Knowledge Acquisition written by James F. Brulé and published by McGraw-Hill Companies. This book was released on 1989 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important practitioner's guide is among the first to formulate a theoretical basis and derive a set of methods for consultants, knowledge engineers, and application programmers who must acquire human expert knowledge to create expert systems. By taking a cybernetic approach to the problems of knowledge acquisition, the authors use a single descriptive vocabulary to deal equally with recursive phenomena, knowledge acquisition, knowledge elicitation, expert system development, and the experts domain/knowledge base descriptions. Following a brief overview of the field, the authors focus on heuristic algorithms, the details of setting up a framework to define a given expertise, the practical interviewing process by which human experts pass on their knowledge to be modeled and coded for use in an expert system. The book concludes with a comprehensive case study selected for its broad application to all areas of knowledge acquisition.

Download or read book Knowledge Oriented Software Design written by J. Cuena and published by . This book was released on 1993 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of AI techniques with traditional information processing approaches to applications design is considered in this volume. More specifically, the feasibility of an AI work area integrating AI based tools with methodologies and with supporting theories, oriented towards general applications design using the knowledge based approach, is discussed.The book is divided into three areas. The first section, Modular Knowledge Architectures, deals with task structured organization of applications and with related knowledge acquisition techniques for application design. The proposals in this area show that the structured approach to knowledge identification and processing may be an alternative to the traditional application development methods which could be named Knowledge Oriented Software Design. The second section considers aspects of Design and Validation at two levels: a more practical approach to assess the life cycle of applications and validation techniques and a more theoretical approach oriented towards automatic programming based on problem solving and inductive logic programming. Basic Techniques to be used in AI applications design such as functional programming, object oriented programming, logic programming and logic based standards for basic knowledge modeling are discussed in the final section.
Download or read book Machine Learning written by R.S. Michalski and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to learn is one of the most fundamental attributes of intelligent behavior. Consequently, progress in the theory and computer modeling of learn ing processes is of great significance to fields concerned with understanding in telligence. Such fields include cognitive science, artificial intelligence, infor mation science, pattern recognition, psychology, education, epistemology, philosophy, and related disciplines. The recent observance of the silver anniversary of artificial intelligence has been heralded by a surge of interest in machine learning-both in building models of human learning and in understanding how machines might be endowed with the ability to learn. This renewed interest has spawned many new research projects and resulted in an increase in related scientific activities. In the summer of 1980, the First Machine Learning Workshop was held at Carnegie-Mellon University in Pittsburgh. In the same year, three consecutive issues of the Inter national Journal of Policy Analysis and Information Systems were specially devoted to machine learning (No. 2, 3 and 4, 1980). In the spring of 1981, a special issue of the SIGART Newsletter No. 76 reviewed current research projects in the field. . This book contains tutorial overviews and research papers representative of contemporary trends in the area of machine learning as viewed from an artificial intelligence perspective. As the first available text on this subject, it is intended to fulfill several needs.
