Download or read book Econometrics of Information and Efficiency written by Jati Sengupta and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Econometrics as an applied discipline attempts to use information in a most efficient manner, yet the information theory and entropy approach developed by Shannon and others has not played much of a role in applied econometrics. Econometrics of Information and Efficiency bridges the gap. Broadly viewed, information theory analyzes the uncertainty of a given set of data and its probabilistic characteristics. Whereas the economic theory of information emphasizes the value of information to agents in a market, the entropy theory stresses the various aspects of imprecision of data and their interactions with the subjective decision processes. The tools of information theory, such as the maximum entropy principle, mutual information and the minimum discrepancy are useful in several areas of statistical inference, e.g., Bayesian estimation, expected maximum likelihood principle, the fuzzy statistical regression. This volume analyzes the applications of these tools of information theory to the most commonly used models in econometrics. The outstanding features of Econometrics of Information and Efficiency are: A critical survey of the uses of information theory in economics and econometrics; An integration of applied information theory and economic efficiency analysis; The development of a new economic hypothesis relating information theory to economic growth models; New lines of research are emphasized.

Download or read book Adversarial Machine Learning written by Aneesh Sreevallabh Chivukula and published by Springer Nature. This book was released on 2023-03-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: A critical challenge in deep learning is the vulnerability of deep learning networks to security attacks from intelligent cyber adversaries. Even innocuous perturbations to the training data can be used to manipulate the behaviour of deep networks in unintended ways. In this book, we review the latest developments in adversarial attack technologies in computer vision; natural language processing; and cybersecurity with regard to multidimensional, textual and image data, sequence data, and temporal data. In turn, we assess the robustness properties of deep learning networks to produce a taxonomy of adversarial examples that characterises the security of learning systems using game theoretical adversarial deep learning algorithms. The state-of-the-art in adversarial perturbation-based privacy protection mechanisms is also reviewed. We propose new adversary types for game theoretical objectives in non-stationary computational learning environments. Proper quantification of the hypothesis set in the decision problems of our research leads to various functional problems, oracular problems, sampling tasks, and optimization problems. We also address the defence mechanisms currently available for deep learning models deployed in real-world environments. The learning theories used in these defence mechanisms concern data representations, feature manipulations, misclassifications costs, sensitivity landscapes, distributional robustness, and complexity classes of the adversarial deep learning algorithms and their applications. In closing, we propose future research directions in adversarial deep learning applications for resilient learning system design and review formalized learning assumptions concerning the attack surfaces and robustness characteristics of artificial intelligence applications so as to deconstruct the contemporary adversarial deep learning designs. Given its scope, the book will be of interest to Adversarial Machine Learning practitioners and Adversarial Artificial Intelligence researchers whose work involves the design and application of Adversarial Deep Learning.

Download or read book Geospatial Approaches to Energy Balance and Breast Cancer written by David Berrigan and published by Springer. This book was released on 2019-07-15 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer occurs in specific places and spaces, each of which have identifiable geographic coordinates, characterized by unique natural, built and social characteristics, all of which contribute significantly to cancer across the spectrum from etiology through diagnosis, treatment and outcomes. In the first volume of this series, published in 2010, a single chapter was focused on these geographic influences. Since then, the field of geospatial studies of cancer prevention and control has exploded in approaches and applications. Accordingly, this volume focuses on what has now become a very specific research endeavor, Geospatial Factors Impacting Breast Cancer. The book provides important insights into this relatively new and rapidly developing field. It should be of value to all students of the Energy Balance & Cancer Series and a wide-ranging introduction to problems in cancer prevention and control for geographers, demographers and other researchers with a geospatial perspective. Moreover, it provides important information for all oncologists, endocrinologists, and behavioral modification professionals to better understand their patients in the context of their environment. It should also provide important considerations for physicians, scientists, public health professionals and disparity investigator planning clinical trials, community interventions and community planning.
Download or read book Business Cycles in the Contemporary World written by Bernd Süssmuth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a thorough and sophisticated descriptive analysis of business cycles in a historical perspective. The study is based on the latest available time series as well as latest techniques from the frequency domain. A combined univariate and bivariate analysis is conducted on the national as well as supranational (G7- and Euro-Area wide) level. Issues of stability, volatility, and cyclicality are investigated jointly. An extensive analysis of US manufacturing investment series on the fairly disaggregated four-digit level highlights the limits of linear models to capture the sectoral aggregation process. Synchronization is modelled by a mode-locking mechanism of industrial investment cycles induced by informational externalities. The model in its stochastic version is numerically simulated to assess an agreement between model and data.
