Algorithmic Learning in a Random World describes recent theoretical and experimental developments in building computable approximations to Kolmogorov's algorithmic notion of randomness. Based on these approximations, a new set of machine learning algorithms have been developed that can be used to make predictions and to estimate their confidence and credibility in high-dimensional spaces under the usual assumption that the data are independent and identically distributed (assumption of randomness). Another aim of this unique monograph is to outline some limits of predictions: The approach based on algorithmic theory of randomness allows for the proof of impossibility of prediction in certain situations. The book describes how several important machine learning problems, such as density estimation in high-dimensional spaces, cannot be solved if the only assumption is randomness.
This book is a fascinating journey along the history of architectural structures over the last 150 years, taking the World Expos as an original unifying thread. Nevertheless, it does not solely focus on the exhibition buildings; on the contrary, these are continuously being related to buildings beyond the scope of the Expos, thus ultimately providing a general vision of the history of modern structures. This essay is destined to become an essential work of reference within the history of architectural structures. It is generously illustrated with more than nine hundred large-scale illustrations, many of which have not appeared in contemporary publications. It offers innumerable facts that will interest architects, engineers or art historians. Likewise, members of the general public far-removed from these fields will also be able to enjoy many of the passages which are accessible to those who do not have any specific knowledge of architecture or engineering.
The year 1879 marked the beginning of one of the longest, bloodiest conflicts of nineteenth-century Latin America. The War of the Pacific pitted Peru and Bolivia against Chile in a struggle initiated over a festering border dispute. The conflict saw Chile's and Peru's armored warships vying for control of sea lanes and included one of the first examples of the use of naval torpedoes.
In The Devil behind the Mirror, Steven Gregory provides a compelling and intimate account of the impact that transnational processes associated with globalization are having on the lives and livelihoods of people in the Dominican Republic. Grounded in ethnographic fieldwork conducted in the adjacent towns of Boca Chica and Andrés, Gregory's study deftly demonstrates how transnational flows of capital, culture, and people are mediated by contextually specific power relations, politics, and history. He explores such topics as the informal economy, the making of a telenova, sex tourism, and racism and discrimination against Haitians, who occupy the lowest rung on the Dominican economic ladder. Innovative, beautifully written, and now updated with a new preface, The Devil behind the Mirror masterfully situates the analysis of global economic change in everyday lives.
In this Element and its accompanying second Element, A Practical Introduction to Regression Discontinuity Designs: Extensions, Matias Cattaneo, Nicolás Idrobo, and Rocıìo Titiunik provide an accessible and practical guide for the analysis and interpretation of regression discontinuity (RD) designs that encourages the use of a common set of practices and facilitates the accumulation of RD-based empirical evidence. In this Element, the authors discuss the foundations of the canonical Sharp RD design, which has the following features: (i) the score is continuously distributed and has only one dimension, (ii) there is only one cutoff, and (iii) compliance with the treatment assignment is perfect. In the second Element, the authors discuss practical and conceptual extensions to this basic RD setup.
