scikit-learn: Machine Learning Simplified
by Trent Hauck Raul Garreta Guillermo Moncecchi Gavin HackelingImplement scikit-learn into every step of the data science pipeline About This Book • Use Python and scikit-learn to create intelligent applications • Discover how to apply algorithms in a variety of situations to tackle common and not-so common challenges in the machine learning domain • A practical, example-based guide to help you gain expertise in implementing and evaluating machine learning systems using scikit-learn Who This Book Is For If you are a programmer and want to explore machine learning and data-based methods to build intelligent applications and enhance your programming skills, this is the course for you. No previous experience with machine-learning algorithms is required. What You Will Learn • Review fundamental concepts including supervised and unsupervised experiences, common tasks, and performance metrics • Classify objects (from documents to human faces and flower species) based on some of their features, using a variety of methods from Support Vector Machines to Naive Bayes • Use Decision Trees to explain the main causes of certain phenomena such as passenger survival on the Titanic • Evaluate the performance of machine learning systems in common tasks • Master algorithms of various levels of complexity and learn how to analyze data at the same time • Learn just enough math to think about the connections between various algorithms • Customize machine learning algorithms to fit your problem, and learn how to modify them when the situation calls for it • Incorporate other packages from the Python ecosystem to munge and visualize your dataset • Improve the way you build your models using parallelization techniques In Detail Machine learning, the art of creating applications that learn from experience and data, has been around for many years. Python is quickly becoming the go-to language for analysts and data scientists due to its simplicity and flexibility; moreover, within the Python data space, scikit-learn is the unequivocal choice for machine learning. The course combines an introduction to some of the main concepts and methods in machine learning with practical, hands-on examples of real-world problems. The course starts by walking through different methods to prepare your data—be it a dataset with missing values or text columns that require the categories to be turned into indicator variables. After the data is ready, you'll learn different techniques aligned with different objectives—be it a dataset with known outcomes such as sales by state, or more complicated problems such as clustering similar customers. Finally, you'll learn how to polish your algorithm to ensure that it's both accurate and resilient to new datasets. You will learn to incorporate machine learning in your applications. Ranging from handwritten digit recognition to document classification, examples are solved step-by-step using scikit-learn and Python. By the end of this course you will have learned how to build applications that learn from experience, by applying the main concepts and techniques of machine learning. Style and Approach Implement scikit-learn using engaging examples and fun exercises, and with a gentle and friendly but comprehensive "learn-by-doing" approach. This is a practical course, which analyzes compelling data about life, health, and death with the help of tutorials. It offers you a useful way of interpreting the data that's specific to this course, but that can also be applied to any other data. This course is designed to be both a guide and a reference for moving beyond the basics of scikit-learn.

sEMG-based Control Strategy for a Hand Exoskeleton System (Springer Theses)
by Nicola SeccianiThis book reports on the design and testing of an sEMG-based control strategy for a fully-wearable low-cost hand exoskeleton. It describes in detail the modifications carried out to the electronics of a previous prototype, covering in turn the implementation of an innovative sEMG classifier for predicting the wearer's motor intention and driving the exoskeleton accordingly. While similar classifier have been widely used for motor intention prediction, their application to wearable device control has been neglected so far. Thus, this book fills a gap in the literature providing readers with extensive information and a source of inspiration for the future design and control of medical and assistive devices.
repeater: 01110010 ...
by Andrew McEwanSHORTLISTED FOR THE 2013 GERALD LAMPAND MEMORIAL AWARDrepeater is a poetic investigation into the coding, function, language, and structure of computer programming. Using the ASCII 8-bit binary code as an acrostic, each lower-case letter of the alphabet is arranged alongside the lines of the title poem. As a result, this poem "programs" an investigation of layered and digitalized language that is coded into the heart of the code itself. Appendixes to this code form supplementary studies, and deviate into additional problems and concepts at the convergence of poetry and computer programming. Ultimately, repeater reveals what happens when the creative variability of poetry is "inputted" into the rigid binaric structure of computer language.

Whether you're installing from scratch or managing mailing lists with thousands of users, qmail provides detailed information about how to make qmail do precisely what you wantqmail concentrates on common tasks like moving a sendmail setup to qmail, or setting up a "POP toaster," a system that provides mail service to a large number of users on other computers sending and retrieving mail remotely. The book also fills crucial gaps in existing documentation, detailing exactly what the core qmail software does.Topics covered include:Installation and configuration, including patching qmailMoving from sendmail to qmailHandling locally and remotely originated messagesManaging virtual domainsLogging qmail activityTuning qmail performanceRunning multiple copies of qmail on the same computerMailing list setup and managementIntegrating the qmail MTA with POP and IMAP deliveryFiltering out spam and virusesIf you need to manage mailing lists, large volumes of mail, or simply find sendmail and other MTAs too complicated, qmail may be exactly what's called for. Our new guide, qmail, will provide the guidance you need to build an email infrastructure that performs well, makes sense, and is easy to maintain.

net.wars
by Wendy GrossmanFull text online version at www.nyupress.org/netwars. Who will rule cyberspace? And why should people care? Recently stories have appeared in a variety of news media, from the sensational to the staid, that portray the Internet as full of pornography, pedophilia, recipes for making bombs, lewd and lawless behavior, and copyright violators. And, for politicians eager for votes, or to people who have never strolled the electronic byways, regulating the Net seems as logical and sensible as making your kids wear seat belts. Forget freedom of speech: children can read this stuff. From the point of view of those on the Net, mass-media's representation of pornography on the Internet grossly overestimates the amount that is actually available, and these stories are based on studies that are at best flawed and at worst fraudulent. To netizens, the panic over the electronic availability of bomb-making recipes and other potentially dangerous material is groundless: the same material is readily available in public libraries. Out on the Net, it seems outrageous that people who have never really experienced it are in a position to regulate it. How then, should the lines be drawn in the grey area between cyberspace and the physical world? In net.wars, Wendy Grossman, a journalist who has covered the Net since 1992 for major publications such as Wired, The Guardian, and The Telegraph, assesses the battles that will define the future of this new venue. From the Church of Scientology's raids on Net users to netizens attempts to overthrow both the Communications Decency Act and the restrictions on the export of strong encryption, net.wars explains the issues and the background behind the headlines. Among the issues covered are net scams, class divisions on the net, privacy issues, the Communications Decency Act, women online, pornography, hackers and the computer underground, net criminals and sociopaths, and more.
