The Elements of Statistical Learning


Book Description

During the past decade there has been an explosion in computation and information technology. With it have come vast amounts of data in a variety of fields such as medicine, biology, finance, and marketing. The challenge of understanding these data has led to the development of new tools in the field of statistics, and spawned new areas such as data mining, machine learning, and bioinformatics. Many of these tools have common underpinnings but are often expressed with different terminology. This book describes the important ideas in these areas in a common conceptual framework. While the approach is statistical, the emphasis is on concepts rather than mathematics. Many examples are given, with a liberal use of color graphics. It should be a valuable resource for statisticians and anyone interested in data mining in science or industry. The book’s coverage is broad, from supervised learning (prediction) to unsupervised learning. The many topics include neural networks, support vector machines, classification trees and boosting---the first comprehensive treatment of this topic in any book. This major new edition features many topics not covered in the original, including graphical models, random forests, ensemble methods, least angle regression & path algorithms for the lasso, non-negative matrix factorization, and spectral clustering. There is also a chapter on methods for “wide” data (p bigger than n), including multiple testing and false discovery rates. Trevor Hastie, Robert Tibshirani, and Jerome Friedman are professors of statistics at Stanford University. They are prominent researchers in this area: Hastie and Tibshirani developed generalized additive models and wrote a popular book of that title. Hastie co-developed much of the statistical modeling software and environment in R/S-PLUS and invented principal curves and surfaces. Tibshirani proposed the lasso and is co-author of the very successful An Introduction to the Bootstrap. Friedman is the co-inventor of many data-mining tools including CART, MARS, projection pursuit and gradient boosting.




The Black Cabinet


Book Description

An in-depth history exploring the evolution, impact, and ultimate demise of what was known in the 1930s and ‘40s as FDR’s Black Cabinet. In 1932 in the midst of the Great Depression, Franklin Delano Roosevelt won the presidency with the help of key African American defectors from the Republican Party. At the time, most African Americans lived in poverty, denied citizenship rights and terrorized by white violence. As the New Deal began, a “black Brain Trust” joined the administration and began documenting and addressing the economic hardship and systemic inequalities African Americans faced. They became known as the Black Cabinet, but the environment they faced was reluctant, often hostile, to change. “Will the New Deal be a square deal for the Negro?” The black press wondered. The Black Cabinet set out to devise solutions to the widespread exclusion of black people from its programs, whether by inventing tools to measure discrimination or by calling attention to the administration’s failures. Led by Mary McLeod Bethune, an educator and friend of Eleanor Roosevelt, they were instrumental to Roosevelt’s continued success with black voters. Operating mostly behind the scenes, they helped push Roosevelt to sign an executive order that outlawed discrimination in the defense industry. They saw victories?jobs and collective agriculture programs that lifted many from poverty?and defeats?the bulldozing of black neighborhoods to build public housing reserved only for whites; Roosevelt’s refusal to get behind federal anti-lynching legislation. The Black Cabinet never won official recognition from the president, and with his death, it disappeared from view. But it had changed history. Eventually, one of its members would go on to be the first African American Cabinet secretary; another, the first African American federal judge and mentor to Thurgood Marshall. Masterfully researched and dramatically told, The Black Cabinet brings to life a forgotten generation of leaders who fought post-Reconstruction racial apartheid and whose work served as a bridge that Civil Rights activists traveled to achieve the victories of the 1950s and ’60s. Praise for The Black Cabinet “A dramatic piece of nonfiction that recovers the history of a generation of leaders that helped create the environment for the civil rights battles in decades that followed Roosevelt’s death.” —Library Journal “Fascinating . . . revealing the hidden figures of a ‘brain trust’ that lobbied, hectored and strong-armed President Franklin Roosevelt to cut African Americans in on the New Deal. . . . Meticulously researched and elegantly written, The Black Cabinet is sprawling and epic, and Watts deftly re-creates whole scenes from archival material.” —Minneapolis Star Tribune




Rational Choice in an Uncertain World


Book Description

In the Second Edition of Rational Choice in an Uncertain World the authors compare the basic principles of rationality with actual behaviour in making decisions. They describe theories and research findings from the field of judgment and decision making in a non-technical manner, using anecdotes as a teaching device. Intended as an introductory textbook for advanced undergraduate and graduate students, the material not only is of scholarly interest but is practical as well. The Second Edition includes: - more coverage on the role of emotions, happiness, and general well-being in decisions - a summary of the new research on the neuroscience of decision processes - more discussion of the adaptive value of (non-rational heuristics) - expansion of the graphics for decision trees, probability trees, and Venn diagrams.
