    This practical, practitioner-oriented guide explains how to design successful architectures for information systems and to see these through to their successful implementation.

    It is also about Python. However, there is much more. The study of algorithms and data structures is central to understanding what computer science is all about. Learning computer science is not unlike learning any other type of difficult subject matter. The only way to be successful is through deliberate and incremental exposure to the fundamental ideas. A beginning computer scientist needs practice so that there is a thorough understanding before continuing on to the more complex parts of the curriculum. In addition, a beginner needs to be given the opportunity to be successful and gain confidence. This textbook is designed to serve as a text for a first course on data structures and algorithms, typically taught as the second course in the computer science curriculum. Even though the second course is considered more advanced than the first course, this book assumes you are beginners at this level. You may still be struggling with some of the basic ideas and skills from a first computer science course and yet be ready to further explore the discipline and continue to practice problem solving. We cover abstract data types and data structures, writing algorithms, and solving problems. We look at a number of data structures and solve classic problems that arise. The tools and techniques that you learn here will be applied over and over as you continue your study of computer science.

    The title says it is the hard way to learn to writecode but it’s actually not. It’s the “hard” way only in that it’s the way people used to teach things. In this book youwill do something incredibly simple that all programmers actually do to learn a language: 1. Go through each exercise. 2. Type in each sample exactly. 3. Make it run.That’s it. This will be very difficult at first, but stick with it. If you go through this book, and do each exercise for1-2 hours a night, then you’ll have a good foundation for moving on to another book. You might not really learn“programming” from this book, but you will learn the foundation skills you need to start learning the language.This book’s job is to teach you the three most basic essential skills that a beginning programmer needs to know:Reading And Writing, Attention To Detail, Spotting Differences.

    Not only are all of our business, scientific, and government transactions now computerized, but the widespread use of digital cameras, publication tools, and bar codes also generate data. On the collection side, scanned text and image platforms, satellite remote sensing systems, and the World Wide Web have flooded us with a tremendous amount of data. This explosive growth has generated an even more urgent need for new techniques and automated tools that can help us transform this data into useful information and knowledge.Like the first edition, voted the most popular data mining book by KD Nuggets readers, this book explores concepts and techniques for the discovery of patterns hidden in large data sets, focusing on issues relating to their feasibility, usefulness, effectiveness, and scalability. However, since the publication of the first edition, great progress has been made in the development of new data mining methods, systems, and applications. This new edition substantially enhances the first edition, and new chapters have been added to address recent developments on mining complex types of data- including stream data, sequence data, graph structured data, social network data, and multi-relational data.A comprehensive, practical look at the concepts and techniques you need to know to get the most out of real business dataUpdates that incorporate input from readers, changes in the field, and more material on statistics and machine learningDozens of algorithms and implementation examples, all in easily understood pseudo-code and suitable for use in real-world, large-scale data mining projectsComplete classroom support for instructors at www.mkp.com/datamining2e companion site

    With it has 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. 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 wrote much of the statistical modeling software in 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, and projection pursuit.

    Introducing students to the many facets of neural networks, this text provides many case studies to illustrate their real-life, practical applications.

    By presenting actual experiences and analyzing them as they are described, the author conveys the developmental thought processes employed and shows a style of thinking that leads to successful results is something that can be learned.

    It's certainly no walk in the park. And, depending on where you've been for your information when it comes to SEO, it might be outdated, or just flat-out wrong. Why is that? Search has been evolving at an uncanny rate in recent years. And, if you're not in the know, then you could end up spinning your wheels and wasting valuable and precious time and resources on techniques that no longer work. The main reason for the recent changes: to increase relevancy. Google's sole mission is to provide the most relevant search results at the top of its searches, in the quickest manner possible. But, in recent years, due to some mischievous behavior at the hand of a small group of people, relevancy began to wane. SEO 2016 :: Understanding Google's Algorithm Adjustments The field of SEO has been changing, all led by Google's onslaught of algorithm adjustments that have decimated and razed some sites while uplifting and building others. Since 2011, Google has made it its mission to hunt out and demote spammy sites that sacrifice user-experience, focus on thin content, or simply spend their time trying to trick and deceive their way to the top of its search results. At the same time, Google has increased its reliance on four major components of trust, that work at the heart of its search algorithm: Trust in Age Trust in Authority Trust in Content Relevancy In this book, you'll learn just how each of these affects Google's search results, and just how you can best optimize your site and content to ensure that you're playing by Google's many rules. And, although there have been many algorithm adjustments over the years, four major ones have shaped and forever changed the search engine landscape: Google Panda Google Penguin Google Hummingbird Google Mobilegeddon We'll discuss the nature of these changes and just how each of these algorithm adjustments have shaped the current landscape in search engine optimization. So what does it take to rank your site today? In order to compete at any level in SEO, you have to earn trust - Google's trust that is. But, what does that take? How can we build trust quickly without jumping through all the hoops? SEO is by no means a small feat. It takes hard work applied consistently overtime. There are no overnight success stories when it comes to SEO. But there are certainly ways to navigate the stormy online waters of Google's highly competitive search. Download SEO 2016 :: Learn Search Engine Optimization Lift the veil on Google's complex search algorithm, and understand just what it takes to rank on Google searches today, not yesterday.

    The novel approach taken here banishes determinants to the end of the book and focuses on the central goal of linear algebra: understanding the structure of linear operators on vector spaces. The author has taken unusual care to motivate concepts and to simplify proofs. For example, the book presents - without having defined determinants - a clean proof that every linear operator on a finite-dimensional complex vector space (or an odd-dimensional real vector space) has an eigenvalue. A variety of interesting exercises in each chapter helps students understand and manipulate the objects of linear algebra. This second edition includes a new section on orthogonal projections and minimization problems. The sections on self-adjoint operators, normal operators, and the spectral theorem have been rewritten. New examples and new exercises have been added, several proofs have been simplified, and hundreds of minor improvements have been made throughout the text.

    With a new introduction, three new chapters, modernized language and methods throughout, and an appendix of challenging and enjoyable practice problems, Calculus Made Easy has been thoroughly updated for the modern reader.
