Available in PDF, EPUB and Kindle. Book excerpt: An argument that qualitative representations—symbolic representations that carve continuous phenomena into meaningful units—are central to human cognition. In this book, Kenneth Forbus proposes that qualitative representations hold the key to one of the deepest mysteries of cognitive science: how we reason and learn about the continuous phenomena surrounding us. Forbus argues that qualitative representations—symbolic representations that carve continuous phenomena into meaningful units—are central to human cognition. Qualitative representations provide a basis for commonsense reasoning, because they enable practical reasoning with very little data; this makes qualitative representations a useful component of natural language semantics. Qualitative representations also provide a foundation for expert reasoning in science and engineering by making explicit the broad categories of things that might happen and enabling causal models that help guide the application of more quantitative knowledge as needed. Qualitative representations are important for creating more human-like artificial intelligence systems with capabilities for spatial reasoning, vision, question answering, and understanding natural language. Forbus discusses, among other topics, basic ideas of knowledge representation and reasoning; qualitative process theory; qualitative simulation and reasoning about change; compositional modeling; qualitative spatial reasoning; and learning and conceptual change. His argument is notable both for presenting an approach to qualitative reasoning in which analogical reasoning and learning play crucial roles and for marshaling a wide variety of evidence, including the performance of AI systems. Cognitive scientists will find Forbus's account of qualitative representations illuminating; AI scientists will value Forbus's new approach to qualitative representations and the overview he offers.

Download or read book Qualitative Spatial Abstraction in Reinforcement Learning written by Lutz Frommberger and published by Springer Science & Business Media. This book was released on 2010-12-13 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reinforcement learning has developed as a successful learning approach for domains that are not fully understood and that are too complex to be described in closed form. However, reinforcement learning does not scale well to large and continuous problems. Furthermore, acquired knowledge specific to the learned task, and transfer of knowledge to new tasks is crucial. In this book the author investigates whether deficiencies of reinforcement learning can be overcome by suitable abstraction methods. He discusses various forms of spatial abstraction, in particular qualitative abstraction, a form of representing knowledge that has been thoroughly investigated and successfully applied in spatial cognition research. With his approach, he exploits spatial structures and structural similarity to support the learning process by abstracting from less important features and stressing the essential ones. The author demonstrates his learning approach and the transferability of knowledge by having his system learn in a virtual robot simulation system and consequently transfer the acquired knowledge to a physical robot. The approach is influenced by findings from cognitive science. The book is suitable for researchers working in artificial intelligence, in particular knowledge representation, learning, spatial cognition, and robotics.
Download or read book The Politics and Ethics of Representation in Qualitative Research written by The Critical The Critical Methodologies Collective and published by Routledge. This book was released on 2021 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers insights on politics and ethics of representation that are relevant to researchers concerned with struggles for justice. It takes moments of discomfort in the qualitative research process as important sites of knowledge for exploring representational practices in critical research. The Politics and Ethics of Representation in Qualitative Research draws on experiences from research processes in nine PhD projects. In some chapters, ethical and political dilemmas related to representational practices are analyzed as experienced in fieldwork. In others, the focus is on the production of representation at the stage of writing. The book deals with questions such as: What does it mean to write about the lives of others? How are ethics and politics of representation intertwined, and how are they distinct? How are politics of representation linked to a practice of solidarity in research? What are the im/possibilities of hope and care in research? Drawing on grounded empirical research, the book offers input to students, PhDs, researchers, practitioners, activists and others dealing with methodological dilemmas from a critical perspective. Instead of ignoring discomforts, or describing them as solved, we stay with them, showing how such a reflective process provides new, ongoing insights.
Download or read book Qualitative GIS written by Meghan Cope and published by SAGE. This book was released on 2009-07-09 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographic Information Systems are an essential tool for analyzing and representing quantitative spatial data. Qualitative GIS explains the recent integration of qualitative research with Geographical Information Systems With a detailed contextualising introduction, the text is organised in three sections: Representation: examines how researchers are using GIS to create new types of representations; working with spatial data, maps, and othervisualizations to incorporate multiple meanings and to provide texture and context. Analysis: discusses the new techniques of analysis that are emerging at the margins between qualitative research and GIS, this in the wider context of a critical review of mixed-methods in geographical research Theory: questions how knowledge is produced, showing how ideas of ′science′ and ′truth′ inform research, and demonstrates how qualitative GIS can be used to interrogate discussions of power, community, and social action Making reference to representation, analysis, and theory throughout, the text shows how to frame questions, collect data, analyze results, and represent findings in a truly integrated way. An important addition to the mixed methods literature, Qualitative GIS will be the standard reference for upper-level students and researchers using qualitative methods and Geographic Information Systems.
Download or read book Readings in Qualitative Reasoning about Physical Systems written by Daniel S. Weld and published by Morgan Kaufmann Publishers. This book was released on 1990 with total page 744 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to reason qualitatively about physical systems is important to understanding and interacting with the world for both humans and intelligent machines. Accordingly, this study has become an important subject of research in the artificial intelligence and cognitive science communities. The goal of "qualitative physics," as the field is sometimes known, is to capture both the commonsense knowledge of the person on the street and the tacit knowledge underlying the quantitative knowledge used by engineers and scientists. "Readings in Qualitative Reasoning About Physical Systems" is an introduction and source book for this dynamic area, presenting reprints of key papers chosen by the editors and a group of expert referees. The editors present introductions discussing the context and significance of each group of articles as well as providing pointers to the rest of the literature. In addition, the volume includes several original papers that are not available elsewhere.
Download or read book Writing and Representing Qualitative Research written by Maria K. E. Lahman and published by SAGE Publications. This book was released on 2021-08-25 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses foundational areas of qualitative writing (such as journal articles and dissertations), aesthetic representations (including poetry and autoethnography), publishing, and reflexivity in representation in one practical and engaging text based on real experiences. Author Maria K.E. Lahman draws on her experiences as a qualitative research professor and writing instructor, and as someone who has published widely in scholarly journals, employing both traditional and more innovative forms of writing. The first part of the book covers writing tips; how to represent data; how to write a qualitative thematic journal article; how to write a qualitative dissertation; and provides guidance on the publication process. The second part encourages the qualitative researcher to move beyond traditional forms of writing and consider how qualitative research can be represented more aesthetically: as poems, autoethnographies, and visually. The book concludes with a chapter on reflexivity in research representations. Throughout, the author provides vivid examples from her own work, and that of graduate students and colleagues.
Download or read book Qualitative Spatial Reasoning written by M. Teresa Escrig and published by IOS Press. This book was released on 1998 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the aim of automatically reasoning with spatial aspects in a cognitive way, several qualitative models have been developed recently in the Qualitative Spatial Reasoning field. However, there is no model to reason with several spatial aspects in a uniform way. Moreover, most of these models simplify spatial objects to points. In this book we present a novel approach for integrating the qualitative concepts of orientation, distance, and cardinal directions, using points as well as extended objects as primitive of reasoning, based on Constraint Logic Programming. The resulting model has been applied to build a qualitative Navigation Simulator on the structured environment of the city of Castellon.

Download or read book Qualitative Reasoning about Physical Systems written by Daniel G Bobrow and published by Elsevier. This book was released on 2012-12-02 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together current work on qualitative reasoning. Its publication reflects the maturity of qualitative reasoning as a research area and the growing interest in problems of reasoning about physical systems.The papers present knowledge bases for a number of very different domains, including heat flow, transistors, and digital computation. A common theme of all these papers is explaining how physical systems work. An important shared criterion is that the behavioral description must be compositional, that is the description of a system's behavior must be derivable from the structure of the system.This material should be of interest to anyone concerned with automated reasoning about the real (physical) world.

Download or read book Media Representations of African American Men and their Consequences for US American Society written by Anne Jeck and published by GRIN Verlag. This book was released on 2021-03-18 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2017 in the subject American Studies - Culture and Applied Geography, grade: 1,3, Justus-Liebig-University Giessen (Department of English), language: English, abstract: The work at hand explores the depiction of African American men in the media and the consequences these specific ways of representation can have on their lives in US American society. Without narrowing the topic down to one particular media type, the present work will focus on both fictional and non-fictional forms of representation, including depictions in movies and TV series as well as displays in the news. By doing so, it shall untangle the tightly interwoven web of both fictional and non-fictional depictions that ensnares African American men in an opposing, yet overlapping way. African American men’s position in contemporary US American society cannot be investigated under the assumption that their current situation results from a monocausal incident. Without confining the frame of investigation to one specific time period, the present work is oriented towards the most current research results, figures and developments available. As data availability depends on the topic of each subchapter individually, the general time frame cannot be narrowed down specifically. Also, as current events are triggered by various chains of causation, they can never be interpreted without being historized, culturalized and politicized. Therefore, they will be set in context, which might create the impression of partially exceeding the idea of topicality. However, the center of attention will stay on topical events that influence on-going developments in the US.
