Book Description
A tutorial-style introduction to a class of methods for extracting independent signals from a mixture of signals originating from different physical sources; includes MatLab computer code examples. Independent component analysis (ICA) is becoming an increasingly important tool for analyzing large data sets. In essence, ICA separates an observed set of signal mixtures into a set of statistically independent component signals, or source signals. In so doing, this powerful method can extract the relatively small amount of useful information typically found in large data sets. The applications for ICA range from speech processing, brain imaging, and electrical brain signals to telecommunications and stock predictions. In Independent Component Analysis, Jim Stone presents the essentials of ICA and related techniques (projection pursuit and complexity pursuit) in a tutorial style, using intuitive examples described in simple geometric terms. The treatment fills the need for a basic primer on ICA that can be used by readers of varying levels of mathematical sophistication, including engineers, cognitive scientists, and neuroscientists who need to know the essentials of this evolving method. An overview establishes the strategy implicit in ICA in terms of its essentially physical underpinnings and describes how ICA is based on the key observations that different physical processes generate outputs that are statistically independent of each other. The book then describes what Stone calls "the mathematical nuts and bolts" of how ICA works. Presenting only essential mathematical proofs, Stone guides the reader through an exploration of the fundamental characteristics of ICA. Topics covered include the geometry of mixing and unmixing; methods for blind source separation; and applications of ICA, including voice mixtures, EEG, fMRI, and fetal heart monitoring. The appendixes provide a vector matrix tutorial, plus basic demonstration computer code that allows the reader to see how each mathematical method described in the text translates into working Matlab computer code.

Book Description
A comprehensive introduction to ICA for students and practitioners Independent Component Analysis (ICA) is one of the most exciting new topics in fields such as neural networks, advanced statistics, and signal processing. This is the first book to provide a comprehensive introduction to this new technique complete with the fundamental mathematical background needed to understand and utilize it. It offers a general overview of the basics of ICA, important solutions and algorithms, and in-depth coverage of new applications in image processing, telecommunications, audio signal processing, and more. Independent Component Analysis is divided into four sections that cover: * General mathematical concepts utilized in the book * The basic ICA model and its solution * Various extensions of the basic ICA model * Real-world applications for ICA models Authors Hyvarinen, Karhunen, and Oja are well known for their contributions to the development of ICA and here cover all the relevant theory, new algorithms, and applications in various fields. Researchers, students, and practitioners from a variety of disciplines will find this accessible volume both helpful and informative.

Book Description
Art in the Age of the Internet, 1989 to Today is the first major thematic group exhibition in the United States to examine the radical impact of internet culture on visual art. Featuring 60 artists, collaborations, and collectives, the exhibition is comprised of over 70 works across a variety of mediums, including painting, performance, photography, sculpture, video, web-based projects, and virtual reality. The exhibition is divided into five sections that explore themes such as emergent ideas of the body and notions of human enhancement; the internet as a site of both surveillance and resistance; the circulation and control of images and information; the possibilities for exploring identity and community afforded by virtual domains; and new economies of visibility accelerated by social media. Throughout, the work in the exhibition addresses the internet-age democratization of culture that comprises our current moment. The earliest work in the exhibition is from 1989, the year that Tim Berners-Lee invented the World Wide Web. This development, and others that followed in quick succession, modernized the internet, and in the process radically changed our way of life--from how we access and generate information, make friends and share experiences, to how we imagine our future bodies and how nations police national security. 1989 also marked a watershed moment across the globe, with significant shifts in politics, geographies, and economies. Events such as the fall of the Berlin Wall and protests in Tiananmen Square signaled the beginning of our current globalized age, which cannot be imagined without the internet.
