How can we select the best performing data-driven model? How can we rigorously estimate its generalization error? Statistical learning theory answers these questions by deriving non-asymptotic bounds on the generalization error of a model or, in other words, by upper bounding the true error of the learned model based just on quantities computed on the available data. However, for a long time, Statistical learning theory has been considered only an abstract theoretical framework, useful for inspiring new learning approaches, but with limited applicability to practical problems. The purpose of this book is to give an intelligible overview of the problems of model selection and error estimation, by focusing on the ideas behind the different statistical learning theory approaches and simplifying most of the technical aspects with the purpose of making them more accessible and usable in practice. The book starts by presenting the seminal works of the 80’s and includes the most recent results. It discusses open problems and outlines future directions for research.

If you're preparing for the new CompTIA 2006 certification in A+, or the current Network+ and Security+ certifications, you'll find this book invaluable. It provides all the information you need to get ready for these exams, including the four new A+ exams -- the required Essentials exam and three elective exams that pertain to your area of specialization. As with other O'Reilly Nutshell books for certification exams, A+, Network+ and Security + in a Nutshell follows a proven style and approach. It reviews all of the topics needed to master each exam in a remarkably concise format, with required knowledge boiled down to the core. Instead of plowing through 500 to 700 pages to prepare for each exam, this book covers each one in approximately 150 pages. And because the objectives for the three elective A+ exams are redundant, and the book covers them in one section. The exams covered include: A+ Essentials: Required for A+ 2006 certification EXAM 220-602: For the A+ IT Technician specialization EXAM 220-603: For the A+ Remote Support Technician specialization EXAM 220-604: For the A+ IT Depot specialization EXAM N10-003: For Network+ Certification EXAM SYO-101: For Security+ Certification Each exam is covered in three parts: Exam Overview, Study Guide and Prep and Practice. Plenty of detailed tables and screen shots are included, along with study notes and practice questions. Once you have completed the exams successfully, you will find this all-in-one book to be a valuable reference to core administration and security skills.
