Download or read book Theory of Zipf's Law and Beyond written by Alexander I. Saichev and published by Springer Science & Business Media. This book was released on 2009-11-04 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zipf’s law is one of the few quantitative reproducible regularities found in e- nomics. It states that, for most countries, the size distributions of cities and of rms (with additional examples found in many other scienti c elds) are power laws with a speci c exponent: the number of cities and rms with a size greater thanS is inversely proportional toS. Most explanations start with Gibrat’s law of proportional growth but need to incorporate additional constraints and ingredients introducing deviations from it. Here, we present a general theoretical derivation of Zipf’s law, providing a synthesis and extension of previous approaches. First, we show that combining Gibrat’s law at all rm levels with random processes of rm’s births and deaths yield Zipf’s law under a “balance” condition between a rm’s growth and death rate. We nd that Gibrat’s law of proportionate growth does not need to be strictly satis ed. As long as the volatility of rms’ sizes increase asy- totically proportionally to the size of the rm and that the instantaneous growth rate increases not faster than the volatility, the distribution of rm sizes follows Zipf’s law. This suggests that the occurrence of very large rms in the distri- tion of rm sizes described by Zipf’s law is more a consequence of random growth than systematic returns: in particular, for large rms, volatility must dominate over the instantaneous growth rate.
Book Synopsis Within Language, Beyond Theories (Volume III) by : Wojciech Malec
Download or read book Within Language, Beyond Theories (Volume III) written by Wojciech Malec and published by Cambridge Scholars Publishing. This book was released on 2015-09-04 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the third volume in the series Within Language, Beyond Theories, which focuses on current linguistic research that surpasses the limits of contemporary theoretical frameworks in order to gain new insights into the structure of the language system and to offer more explanatorily adequate accounts of linguistic phenomena taken from a number of the world’s languages. This book offers a collection of fourteen chapters organized into three parts and serves as a vehicle for the survey of new voices in discourse analysis, pragmatics and corpus-based studies. Part I addresses a panorama of topics related to different discourse types, such as talk show discourse, multimodal discourse, and everyday spoken discourse, as well as written academic discourse. Part II covers a range of highly controversial issues in pragmatics, including the status of ad-hoc concepts, linguistically encoded meaning, explicit content, and the lexicographic treatment of modality. Part III encompasses chapters which offer an overview of some of the recent phenomena covered in the area of corpus-based research, including the semantic functions of the temporal meanings of selected prepositions; the diffusion of gerundive complements; the institutionalization and de-institutionalization of neologisms; contextual factors in the placement of the adverb “well”; the behaviour of the verb “bake” in copular constructions; the syntactic flexibility of English idioms and their thematic composition; tendencies in the formation of nouns in tabloids; and the application of cluster analysis to the categorization of linguistic data. Drawing on recent advances in discourse analysis, pragmatics and corpus-based studies, the majority of the issues discussed here are approached and investigated from a dual perspective. While on the theoretical side, an array of different theoretical models is surveyed, in the analytical parts, the practical applications of the models examined are tested against data from English (both British and American), Estonian and Polish. The wide range of theoretical and empirical issues discussed in this book will help to provoke further academic discussion on the study of language in the areas of discourse analysis, pragmatics, and corpus-based research.

Book Synopsis Information Theory and Language by : Łukasz Dębowski
Download or read book Information Theory and Language written by Łukasz Dębowski and published by MDPI. This book was released on 2020-12-15 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Information Theory and Language” is a collection of 12 articles that appeared recently in Entropy as part of a Special Issue of the same title. These contributions represent state-of-the-art interdisciplinary research at the interface of information theory and language studies. They concern in particular: • Applications of information theoretic concepts such as Shannon and Rényi entropies, mutual information, and rate–distortion curves to the research of natural languages; • Mathematical work in information theory inspired by natural language phenomena, such as deriving moments of subword complexity or proving continuity of mutual information; • Empirical and theoretical investigation of quantitative laws of natural language such as Zipf’s law, Herdan’s law, and Menzerath–Altmann’s law; • Empirical and theoretical investigations of statistical language models, including recently developed neural language models, their entropies, and other parameters; • Standardizing language resources for statistical investigation of natural language; • Other topics concerning semantics, syntax, and critical phenomena. Whereas the traditional divide between probabilistic and formal approaches to human language, cultivated in the disjoint scholarships of natural sciences and humanities, has been blurred in recent years, this book can contribute to pointing out potential areas of future research cross-fertilization.
Book Synopsis Statistical Universals of Language by : Kumiko Tanaka-Ishii
Download or read book Statistical Universals of Language written by Kumiko Tanaka-Ishii and published by Springer Nature. This book was released on 2021-04-01 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores the universal mathematical properties underlying big language data and possible reasons why such properties exist, revealing how we may be unconsciously mathematical in our language use. These properties are statistical and thus different from linguistic universals that contribute to describing the variation of human languages, and they can only be identified over a large accumulation of usages. The book provides an overview of state-of-the art findings on these statistical universals and reconsiders the nature of language accordingly, with Zipf's law as a well-known example. The main focus of the book further lies in explaining the property of long memory, which was discovered and studied more recently by borrowing concepts from complex systems theory. The statistical universals not only possibly lie as the precursor of language system formation, but they also highlight the qualities of language that remain weak points in today's machine learning. In summary, this book provides an overview of language's global properties. It will be of interest to anyone engaged in fields related to language and computing or statistical analysis methods, with an emphasis on researchers and students in computational linguistics and natural language processing. While the book does apply mathematical concepts, all possible effort has been made to speak to a non-mathematical audience as well by communicating mathematical content intuitively, with concise examples taken from real texts.

Download or read book Beyond Digital written by Mario Carpo and published by MIT Press. This book was released on 2023-04-18 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recasting computational design: a new modern agenda for a post-industrial, post-pandemic world. Mass production was the core technical logic of industrial modernity: for the last hundred years, architects and designers have tried to industrialize construction and standardize building materials and processes in the pursuit of economies of scale. But this epochal march of modernity is now over. In Beyond Digital, Mario Carpo reviews the long history of the computational mode of production, showing how the merger of robotic automation and artificial intelligence will stop and reverse the modernist quest for scale. Today’s technologies already allow us to use nonstandard building materials as found, or as made, and assemble them in as many nonstandard, intelligent, adaptive ways as needed: the microfactories of our imminent future will be automated artisan shops. The post-industrial logic of computational manufacturing has been known and theorized for some time. By tracing its theoretical and technical sources, and reviewing the design theories that accompanied its rise, Carpo shows how the computational project, long under the sway of powerful antimodern ideologies, is now being recast by the urgency of the climate crisis, which has vindicated its premises—and by the global pandemic, which has tragically proven its viability. Looking at the work of a new generation of designers, technologists, and producers, Beyond Digital offers a new modern agenda for our post-industrial future.
Book Synopsis Statistical Properties in Firms’ Large-scale Data by : Atushi Ishikawa
Download or read book Statistical Properties in Firms’ Large-scale Data written by Atushi Ishikawa and published by Springer Nature. This book was released on 2021-06-25 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to provide a systematic description of statistical properties of large-scale financial data. Specifically, the power-law and log-normal distributions observed at a given time and their changes using time-reversal symmetry, quasi-time-reversal symmetry, Gibrat's law, and the non-Gibrat's property observed in a short-term period are derived here. The statistical properties observed over a long-term period, such as power-law and exponential growth, are also derived. These subjects have not been thoroughly discussed in the field of economics in the past, and this book is a compilation of the author's series of studies by reconstructing the data analyses published in 15 academic journals with new data. This book provides readers with a theoretical and empirical understanding of how the statistical properties observed in firms’ large-scale data are related along the time axis. It is possible to expand this discussion to understand theoretically and empirically how the statistical properties observed among differing large-scale financial data are related. This possibility provides readers with an approach to microfoundations, an important issue that has been studied in economics for many years.
Book Synopsis Beyond the Learning Curve by : Craig Speelman
Download or read book Beyond the Learning Curve written by Craig Speelman and published by OUP Oxford. This book was released on 2005-10-13 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: For years now, learning has been at the heart of research within cognitive psychology. How do we acquire new knowledge and new skills? Are the principles underlying skill acquisition unique to learning, or similar to those underlying other behaviours? Is the mental system essentially modular, or is the mental system a simple product of experience, a product that, inevitably, reflects the shape of the external world with all of its specialisms and similarities? This new book takes the view that learning is a major influence on the nature of the processes and representations that fill our minds. Throughout, the authors review and consider the areas of skill acquisition and lexical representation to illustrate the effects that practice can have on cognitive processes. They also draw parallels between theories in physical and biological domains to propose not only a new theory of mental function but also demonstrate that the mind is essentially subject to the same natural laws as the physical world. In so doing Speelman and Kirsner present a new perspective on psychology - one that identifies universal principles underlying all behaviours and one which contrasts markedly from our current focus on highly specific behaviours. Accessibly written, Beyond the Learning Curve is a thought provoking and challenging new text for students and researchers in the cognitive sciences.

Book Synopsis A Crude Look at the Whole by : John H. Miller
Download or read book A Crude Look at the Whole written by John H. Miller and published by Basic Books. This book was released on 2016-01-05 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: A top expert explains why a social and economic understanding of complex systems will help society to anticipate and confront our biggest challenges Imagine trying to understand a stained glass window by breaking it into pieces and examining it one shard at a time. While you could probably learn a lot about each piece, you would have no idea about what the entire picture looks like. This is reductionism -- the idea that to understand the world we only need to study its pieces -- and it is how most social scientists approach their work. In A Crude Look at the Whole, social scientist and economist John H. Miller shows why we need to start looking at whole pictures. For one thing, whether we are talking about stock markets, computer networks, or biological organisms, individual parts only make sense when we remember that they are part of larger wholes. And perhaps more importantly, those wholes can take on behaviors that are strikingly different from that of their pieces. Miller, a leading expert in the computational study of complex adaptive systems, reveals astounding global patterns linking the organization of otherwise radically different structures: It might seem crude, but a beehive's temperature control system can help predict market fluctuations and a mammal's heartbeat can help us understand the "heartbeat" of a city and adapt urban planning accordingly. From enduring racial segregation to sudden stock market disasters, once we start drawing links between complex systems, we can start solving what otherwise might be totally intractable problems. Thanks to this revolutionary perspective, we can finally transcend the limits of reductionism and discover crucial new ideas. Scientifically founded and beautifully written, A Crude Look at the Whole is a powerful exploration of the challenges that we face as a society. As it reveals, taking the crude look might be the only way to truly see.

Download or read book Benford's Law written by Steven J. Miller and published by Princeton University Press. This book was released on 2015-06-09 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Benford's law states that the leading digits of many data sets are not uniformly distributed from one through nine, but rather exhibit a profound bias. This bias is evident in everything from electricity bills and street addresses to stock prices, population numbers, mortality rates, and the lengths of rivers. Here, Steven Miller brings together many of the world’s leading experts on Benford’s law to demonstrate the many useful techniques that arise from the law, show how truly multidisciplinary it is, and encourage collaboration. Beginning with the general theory, the contributors explain the prevalence of the bias, highlighting explanations for when systems should and should not follow Benford’s law and how quickly such behavior sets in. They go on to discuss important applications in disciplines ranging from accounting and economics to psychology and the natural sciences. The contributors describe how Benford’s law has been successfully used to expose fraud in elections, medical tests, tax filings, and financial reports. Additionally, numerous problems, background materials, and technical details are available online to help instructors create courses around the book. Emphasizing common challenges and techniques across the disciplines, this accessible book shows how Benford’s law can serve as a productive meeting ground for researchers and practitioners in diverse fields.
Book Synopsis Scale Invariance and Beyond by : B. Dubrulle
Download or read book Scale Invariance and Beyond written by B. Dubrulle and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an excellent introduction to the concept of scale invariance, which is a growing field of research with wide applications. It describes where and how symmetry under scale transformation (and its various forms of partial breakdown) can be used to analyze solutions of a problem without the need to explicitly solve it. The first part gives descriptions of tools and concepts; the second is devoted to recent attempts to go beyond the invariance or symmetry breaking, to discuss causes and consequences, and to extract useful information about the system. Examples are carefully worked out in fields as diverse as condensed matter physics, population dynamics, earthquake physics, turbulence, cosmology and finance.
