Available in PDF, EPUB and Kindle. Book excerpt: This monograph is a contribution to the study of the identification problem: the problem of identifying an item from a known class us ing positive and negative examples. This problem is considered to be an important component of the process of inductive learning, and as such has been studied extensively. In the overview we shall explain the objectives of this work and its place in the overall fabric of learning research. Context. Learning occurs in many forms; the only form we are treat ing here is inductive learning, roughly characterized as the process of forming general concepts from specific examples. Computer Science has found three basic approaches to this problem: • Select a specific learning task, possibly part of a larger task, and construct a computer program to solve that task . • Study cognitive models of learning in humans and extrapolate from them general principles to explain learning behavior. Then construct machine programs to test and illustrate these models. xi Xll PREFACE • Formulate a mathematical theory to capture key features of the induction process. This work belongs to the third category. The various studies of learning utilize training examples (data) in different ways. The three principal ones are: • Similarity-based (or empirical) learning, in which a collection of examples is used to select an explanation from a class of possible rules.

Available in PDF, EPUB and Kindle. Book excerpt: An accessible primer on how to create effective graphics from data This book provides students and researchers a hands-on introduction to the principles and practice of data visualization. It explains what makes some graphs succeed while others fail, how to make high-quality figures from data using powerful and reproducible methods, and how to think about data visualization in an honest and effective way. Data Visualization builds the reader’s expertise in ggplot2, a versatile visualization library for the R programming language. Through a series of worked examples, this accessible primer then demonstrates how to create plots piece by piece, beginning with summaries of single variables and moving on to more complex graphics. Topics include plotting continuous and categorical variables; layering information on graphics; producing effective “small multiple” plots; grouping, summarizing, and transforming data for plotting; creating maps; working with the output of statistical models; and refining plots to make them more comprehensible. Effective graphics are essential to communicating ideas and a great way to better understand data. This book provides the practical skills students and practitioners need to visualize quantitative data and get the most out of their research findings. Provides hands-on instruction using R and ggplot2 Shows how the “tidyverse” of data analysis tools makes working with R easier and more consistent Includes a library of data sets, code, and functions

Book excerpt: Highlights the pitfalls of data analysis and emphasizes the importance of using the appropriate metrics before making key decisions.Big data is often touted as the key to understanding almost every aspect of contemporary life. This critique of "information hubris" shows that even more important than data is finding the right metrics to evaluate it.The author, an expert in environmental design and city planning, examines the many ways in which we measure ourselves and our world. He dissects the metrics we apply to health, worker productivity, our children's education, the quality of our environment, the effectiveness of leaders, the dynamics of the economy, and the overall well-being of the planet. Among the areas where the wrong metrics have led to poor outcomes, he cites the fee-for-service model of health care, corporate cultures that emphasize time spent on the job while overlooking key productivity measures, overreliance on standardized testing in education to the detriment of authentic learning, and a blinkered focus on carbon emissions, which underestimates the impact of industrial damage to our natural world. He also examines various communities and systems that have achieved better outcomes by adjusting the ways in which they measure data. The best results are attained by those that have learned not only what to measure and how to measure it, but what it all means. By highlighting the pitfalls inherent in data analysis, this illuminating book reminds us that not everything that can be counted really counts.

Available in PDF, EPUB and Kindle. Book excerpt: Ten years ago Bill Gale of AT&T Bell Laboratories was primary organizer of the first Workshop on Artificial Intelligence and Statistics. In the early days of the Workshop series it seemed clear that researchers in AI and statistics had common interests, though with different emphases, goals, and vocabularies. In learning and model selection, for example, a historical goal of AI to build autonomous agents probably contributed to a focus on parameter-free learning systems, which relied little on an external analyst's assumptions about the data. This seemed at odds with statistical strategy, which stemmed from a view that model selection methods were tools to augment, not replace, the abilities of a human analyst. Thus, statisticians have traditionally spent considerably more time exploiting prior information of the environment to model data and exploratory data analysis methods tailored to their assumptions. In statistics, special emphasis is placed on model checking, making extensive use of residual analysis, because all models are 'wrong', but some are better than others. It is increasingly recognized that AI researchers and/or AI programs can exploit the same kind of statistical strategies to good effect. Often AI researchers and statisticians emphasized different aspects of what in retrospect we might now regard as the same overriding tasks.

Book excerpt: A new way of thinking about data science and data ethics that is informed by the ideas of intersectional feminism. Today, data science is a form of power. It has been used to expose injustice, improve health outcomes, and topple governments. But it has also been used to discriminate, police, and surveil. This potential for good, on the one hand, and harm, on the other, makes it essential to ask: Data science by whom? Data science for whom? Data science with whose interests in mind? The narratives around big data and data science are overwhelmingly white, male, and techno-heroic. In Data Feminism, Catherine D'Ignazio and Lauren Klein present a new way of thinking about data science and data ethics—one that is informed by intersectional feminist thought. Illustrating data feminism in action, D'Ignazio and Klein show how challenges to the male/female binary can help challenge other hierarchical (and empirically wrong) classification systems. They explain how, for example, an understanding of emotion can expand our ideas about effective data visualization, and how the concept of invisible labor can expose the significant human efforts required by our automated systems. And they show why the data never, ever “speak for themselves.” Data Feminism offers strategies for data scientists seeking to learn how feminism can help them work toward justice, and for feminists who want to focus their efforts on the growing field of data science. But Data Feminism is about much more than gender. It is about power, about who has it and who doesn't, and about how those differentials of power can be challenged and changed.

Available in PDF, EPUB and Kindle. Book excerpt: In this moving account, “America’s Superintendent” John Kuhn lays bare the scare tactics at the root of the modern school “reform” movement. Kuhn conveys a deeply held passion for the mission and promise of public education through his own experience as a school administrator in Texas. When his “Alamo Letter” first appeared in the Washington Post, it galvanized the educational community in a call to action that was impossible to ignore. This powerful book requires us to question whether the current education crisis will be judged by history as a legitimate national emergency or an agenda-driven panic, spurred on by a media that is, for the most part, uninterested in anything but useless soundbites. Essential reading for teachers, administrators, policymakers, and everyone concerned with public education, Fear and Learning in America: Analyzes school reform from the perspective of a practicing school administrator who isn’t sold on the corporate reform package. Places school reform in the historical context of similar episodes of national hand-wringing. Offers encouragement and appreciation to classroom teachers who are exhausted by the vilification that modern school reform has served up. “John Kuhn’s book is packed with more wisdom than any 10 books that I have read about American education. It is the wisdom born of experience. It is the wisdom of a man who cares about children, families, and community.” —From the Foreword by Diane Ravitch, author of Reign of Error “In Fear and Learning in America, John Kuhn weaves together stories from his life as a teacher and missionary with tales from history. The result is a fresh way of thinking about schools and educational policy. Refuting A Nation at Risk, Mr. Kuhn warns, persuasively, of ‘a rising tide of inequality.’ His message, artfully delivered in this important book, should be heeded.” —John Merrow, education correspondent, PBS NewsHour, and president, Learning Matters, Inc. “Kuhn is a superb educator and his valuable book effectively dissects the myths about today’s high-stakes testing environment and the worsening conditions under which educators are expected to make miracles every day, or else. His cogent arguments against such policies demonstrate what is really important and should inform the debate about public education.” —Randi Weingarten, president, American Federation of Teachers “This book is a brilliantly clear defense of public education as our nation’s most valuable asset. John Kuhn fearlessly names the fact that today’s education reformers, like the renowned emperor, wear no clothes.” —Christine Sleeter, professor emerita, California State University Monterey Bay John Kuhn is a public school administrator in Texas and a vocal advocate for public education. His “Alamo Letter” and YouTube videos of his 2011 speech at a Save Texas Schools rally went viral, as did his 2012 essay, “The Exhaustion of the American Teacher.”
