philipp k janert: Data Analysis with Open Source Tools Philipp K. Janert, 2010-11-11 Collecting data is relatively easy, but turning raw information into something useful requires that you know how to extract precisely what you need. With this insightful book, intermediate to experienced programmers interested in data analysis will learn techniques for working with data in a business environment. You'll learn how to look at data to discover what it contains, how to capture those ideas in conceptual models, and then feed your understanding back into the organization through business plans, metrics dashboards, and other applications. Along the way, you'll experiment with concepts through hands-on workshops at the end of each chapter. Above all, you'll learn how to think about the results you want to achieve -- rather than rely on tools to think for you. Use graphics to describe data with one, two, or dozens of variables Develop conceptual models using back-of-the-envelope calculations, as well asscaling and probability arguments Mine data with computationally intensive methods such as simulation and clustering Make your conclusions understandable through reports, dashboards, and other metrics programs Understand financial calculations, including the time-value of money Use dimensionality reduction techniques or predictive analytics to conquer challenging data analysis situations Become familiar with different open source programming environments for data analysis Finally, a concise reference for understanding how to conquer piles of data.--Austin King, Senior Web Developer, Mozilla An indispensable text for aspiring data scientists.--Michael E.

philipp k janert: Manuscript Cultures: Mapping the Field Jörg Quenzer, Dmitry Bondarev, Jan-Ulrich Sobisch, 2014-12-12 Script and writing were among the most important inventions in human history, and until the invention of printing, the handwritten book was the primary medium of literary and cultural transmission. Although the study of manuscripts is already quite advanced for many regions of the world, no unified discipline of ‘manuscript studies’ has yet evolved which is capable of treating handwritten books from East Asia, India and the Islamic world equally alongside the European manuscript tradition. This book, which aims to begin the interdisciplinary dialogue needed to arrive at a truly systematic and comparative approach to manuscript cultures worldwide, brings together papers by leading researchers concerned with material, philological and cultural aspects of different manuscript traditions. |

philipp k janert: Think Stats Allen B. Downey, 2011-07-01 If you know how to program, you have the skills to turn data into knowledge using the tools of probability and statistics. This concise introduction shows you how to perform statistical analysis computationally, rather than mathematically, with programs written in Python. You'll work with a case study throughout the book to help you learn the entire data analysis process—from collecting data and generating statistics to identifying patterns and testing hypotheses. Along the way, you'll become familiar with distributions, the rules of probability, visualization, and many other tools and concepts. Develop your understanding of probability and statistics by writing and testing code Run experiments to test statistical behavior, such as generating samples from several distributions Use simulations to understand concepts that are hard to grasp mathematically Learn topics not usually covered in an introductory course, such as Bayesian estimation Import data from almost any source using Python, rather than be limited to data that has been cleaned and formatted for statistics tools Use statistical inference to answer questions about real-world data |
philipp k janert: Problems of Chronology in Gandhāran Art Wannaporn Rienjang, Peter Stewart, 2018-03-14 Since the beginning of Gandhāran studies in the nineteenth century, chronology has been one of the most significant challenges to the understanding of Gandhāran art. Many other ancient societies, including those of Greece and Rome, have left a wealth of textual sources which have put their fundamental chronological frameworks beyond doubt. In the absence of such sources on a similar scale, even the historical eras cited on inscribed Gandhāran works of art have been hard to place. Few sculptures have such inscriptions and the majority lack any record of find-spot or even general provenance. Those known to have been found at particular sites were sometimes moved and reused in antiquity. Consequently, the provisional dates assigned to extant Gandhāran sculptures have sometimes differed by centuries, while the narrative of artistic development remains doubtful and inconsistent. Building upon the most recent, cross-disciplinary research, debate and excavation, this volume reinforces a new consensus about the chronology of Gandhāra, bringing the history of Gandhāran art into sharper focus than ever. By considering this tradition in its wider context, alongside contemporary Indian art and subsequent developments in Central Asia, the authors also open up fresh questions and problems which a new phase of research will need to address. Problems of Chronology in Gandhāran Art is the first publication of the Gandhāra Connections project at the University of Oxford’s Classical Art Research Centre, which has been supported by the Bagri Foundation and the Neil Kreitman Foundation. It presents the proceedings of the first of three international workshops on fundamental questions in the study of Gandhāran art, held at Oxford in March 2017. |

philipp k janert: Big Data Now: Current Perspectives from O'Reilly Radar O'Reilly Radar Team, 2011-08-30 This collection represents the full spectrum of data-related content we’ve published on O’Reilly Radar over the last year. Mike Loukides kicked things off in June 2010 with “What is data science?” and from there we’ve pursued the various threads and themes that naturally emerged. Now, roughly a year later, we can look back over all we’ve covered and identify a number of core data areas: Data issues -- The opportunities and ambiguities of the data space are evident in discussions around privacy, the implications of data-centric industries, and the debate about the phrase “data science” itself. The application of data: products and processes – A “data product” can emerge from virtually any domain, including everything from data startups to established enterprises to media/journalism to education and research. Data science and data tools -- The tools and technologies that drive data science are of course essential to this space, but the varied techniques being applied are also key to understanding the big data arena. The business of data – Take a closer look at the actions connected to data -- the finding, organizing, and analyzing that provide organizations of all sizes with the information they need to compete. |
