Download or read book Feature Engineering for Machine Learning written by Alice Zheng and published by "O'Reilly Media, Inc.". This book was released on 2018-03-23 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feature engineering is a crucial step in the machine-learning pipeline, yet this topic is rarely examined on its own. With this practical book, you’ll learn techniques for extracting and transforming features—the numeric representations of raw data—into formats for machine-learning models. Each chapter guides you through a single data problem, such as how to represent text or image data. Together, these examples illustrate the main principles of feature engineering. Rather than simply teach these principles, authors Alice Zheng and Amanda Casari focus on practical application with exercises throughout the book. The closing chapter brings everything together by tackling a real-world, structured dataset with several feature-engineering techniques. Python packages including numpy, Pandas, Scikit-learn, and Matplotlib are used in code examples. You’ll examine: Feature engineering for numeric data: filtering, binning, scaling, log transforms, and power transforms Natural text techniques: bag-of-words, n-grams, and phrase detection Frequency-based filtering and feature scaling for eliminating uninformative features Encoding techniques of categorical variables, including feature hashing and bin-counting Model-based feature engineering with principal component analysis The concept of model stacking, using k-means as a featurization technique Image feature extraction with manual and deep-learning techniques

Download or read book Foundations for Feature Engineering of Software Systems written by and published by . This book was released on 1996 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The gulf between the user's and the developer's perspectives leads to difficulties in producing successful software systems. Users are focused on the problem domain, where the system's features are the primary concern, and developers are focused on the solution domain, where the system's life cycle artifacts are key. Presently, there is little understanding of how to narrow this gulf. This paper presents an organizing viewpoint that the authors term "feature engineering." Feature engineering promotes features as first-class objects throughout the software life cycle and across the problem and solution domains. They present a model of life cycle artifacts and show how features can be incorporated into that model. They then discuss the application of feature engineering to a variety of life cycle activities, examining in depth its effect on architectural design.

Download or read book Python Bookcamp written by Vaskaran Sarcar and published by . This book was released on 2021-01-16 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Python Bookcamp: Exercises and Projects is a beginner''s book. It is a quick programming guide to the Python programming language. The best way of learning is by doing exercises and projects. Therefore, this book follows the boot camp approach. It enables you to make interesting programs in no time.The world is changing, and we keep extra features developing, but the core concepts are evergreen. We build all additional features on top of those. If you have a sound foundation, you can adopt the upcoming features quickly. You also understand the reason behibrnd those changes. So, the book focuses on core topics in-depth, but it does not cover "A-Z" in Python at the same time. The book has 12 chapters. The first chapter is a simple warm-up session for you. Here you''ll set up your programming environment. The second chapter talks about the Python basics. Here you learn about variables, operators, and comments. Each subsequent chapter contains exercises and hands-on projects for you. As you move on, these projects will be more complex. You implement the case studies using the concepts you learn in a previous chapter. At the beginning of these chapters, you get a description of the projects. Once you finish reading these chapters, you get the complete solutions.The book covers both the common and the advanced data types along with the topic of loop and decision making. It also covers file handling, functions, and modules with exception handling mechanisms too. The last chapters of this book cover the object-oriented programming basics. Here you see the usage of classes, objects, and inheritance. You''ll also learn about static and class methods in Python. In the end, there is a chapter to show you how to write useful tests to verify your code. In most cases, you''ll see the complete programs with output. It means you can continue reading the material without interruption. To write the very short programs, or to test the simple commands, I use a Python command shell. For the remaining cases, you see the usage of PyCharm Community Edition in a Windows10 environment. This is a very popular IDE, and this version is free at the time of this writing. Many of us are afraid of fat books. They do not promise that you can complete the book in one day or 7 days, etc. Here is the twist. You should not forget that learning is a continuous process. We can achieve no real mastery in a short period. So, the motto of the book is "To learn the core topics in Python, whatever efforts I need to put, I am OK with that". I believe that if you have a strong focus, you can complete one chapter in a day with no trouble. So, the simple arithmetic says that you can complete the book in 12 days. But it is secondary! I have designed the book in such a way that upon completion of the book, you will learn the core concepts in depth. And you''ll know how to learn further. In short, you can pick the book if the answer is "yes" to the following questions: *Have you never programmed before, but eager to learn Python? *Do you want to explore the Python essentials step-by-step, but as quickly as possible? *Do you have experience with a high-level programming languages, but want to learn Python ? *Do you know how to install software on a machine and then set up the coding environment? *Do you like to review your knowledge before you use Python in advanced fields such as data science, machine learning? Probably you shouldn''t read this book if the answer is yes to any of the following questions: *Are you confident about the fundamentals of Python? *Are you looking for advanced concepts in Python only? *Do you dislike a book that has an emphasis on exercises? *"I dislike Windows OS, and PyCharm. I want to learn and use Python without them only."-is this statement true for you? The source code and other details are available at https://github.com/Vaskaran/PythonBookcamp
