What do pure mathematicians do, and why do they do it? Looking beyond the conventional answers, this book offers an eclectic panorama of the lives and values and hopes and fears of mathematicians in the twenty-first century, assembling material from a startlingly diverse assortment of scholarly, journalistic, and pop culture sources. Drawing on the author's personal experiences as well as the thoughts and opinions of mathematicians from Archimedes and Omar Khayyám to such contemporary giants as Alexander Grothendieck and Robert Langlands, the book reveals the charisma and romance of mathematics as well as its darker side. In this portrait of mathematics as a community united around a set of common intellectual, ethical, and existential challenges, the book touches on a wide variety of questions, such as: Are mathematicians to blame for the 2008 financial crisis? How can we talk about the ideas we were born too soon to understand? And how should you react if you are asked to explain number theory at a dinner party? The book takes readers on an unapologetic guided tour of the mathematical life, from the philosophy and sociology of mathematics to its reflections in film and popular music, with detours through the mathematical and mystical traditions of Russia, India, medieval Islam, the Bronx, and beyond.

AbstractThe last decade brought significant advances in automatic speech recognition (ASR) thanks to the evolution of deep learning methods. ASR systems evolved from pipeline-based systems, that modeled hand-crafted speech features with probabilistic frameworks and generated phone posteriors, to end-to-end (E2E) systems, that translate the raw waveform directly into words using one deep neural network (DNN). The transcription accuracy greatly increased, leading to ASR technology being integrated into many commercial applications. However, few of the existing ASR technologies are suitable for integration in embedded applications, due to their hard constrains related to computing power and memory usage. This overview paper serves as a guided tour through the recent literature on speech recognition and compares the most popular ASR implementations. The comparison emphasizes the trade-off between ASR performance and hardware requirements, to further serve decision makers in choosing the system which fits best their embedded application. To the best of our knowledge, this is the first study to provide this kind of trade-off analysis for state-of-the-art ASR systems.

Abstract Recently, an interest in archives and archiving has been noticeable amongst artists as well as scholars. This paper analyses Mette Ingvartsen’s 69 Positions (2014), a dance work in which the audience participates in a guided tour through Ingvartsen’s own “archive”. The aim is to look at how archival traces and archival practices “perform” in the work, with a specific focus on bodily archiving. As a theoretical framework, I draw mainly on André Lepecki’s (2016) conceptualization of “the body as archive”, whereby reenacting becomes a mode of inventive archiving that actualizes not-yet utilized potential in a work. In this analysis, I propose that Ingvartsen’s body and the bodies of the audience create a collective body-archive, which collectively actualizes (previously virtual) intimacy. In addition, I argue that blurring the distinctions between body and archive and between reenactment and archiving are ways of insisting that dance does not disappear but remains, counter to “archival logic” (Schneider 2011, 99), by being stored in bodies and transmitted between bodies and by repeatedly reappearing–always more or less altered–in or as performance.
