Book excerpt: Welcome everyone to the book "Power BI DAX Dictionary: Function-by-Function Explained" In today's era of digital transformation, the power of data cannot be underestimated. Power BI, one of the renowned tools for Business Intelligence and data analysis, has become a crucial instrument in transforming data into valuable insights and gaining a deeper understanding of business. Power BI is a dynamic suite of business analytics tools developed by Microsoft, designed to empower organizations with interactive visualizations and business intelligence capabilities. It allows users to connect to various data sources, transform raw data into meaningful information, and share insights across the organization. DAX (Data Analysis Expressions), on the other hand, is the formula language used in Power BI and other Microsoft tools like Excel Power Pivot and Analysis Services Tabular. DAX is the key to unlocking the full potential of Power BI, enabling users to create sophisticated calculations and custom measures to analyze data in powerful ways. In "Power BI DAX Dictionary: Function-by-Function Explained" we embark on a comprehensive journey through the world of DAX functions. DAX can be a formidable landscape to navigate, but fear not! This book is your guide, breaking down each function, explaining its purpose, syntax, and usage, and providing practical examples to illustrate how it can be applied in real-world scenarios. Whether you are a data analyst, business intelligence professional, or simply someone interested in harnessing the power of data for better decision-making, this book is designed to be your companion in mastering DAX functions within the context of Power BI. In each chapter, we will explore a specific group of DAX functions, categorizing them based on their functional purposes, demystifying their complexities, and equipping you with the tools to effectively harness their potential. By the conclusion of this book, you will possess a strong grasp of these DAX function groups and the confidence to apply them for extracting actionable insights from your data. Get ready to explore the Function-by-Function DAX Dictionary, and let's embark on a journey of data discovery and analytical excellence with Power BI!

Download or read book Power BI DAX Simplified written by Reza Rad and published by Independently Published. This book was released on 2021-07-17 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: DAX is the language of data analysis in Microsoft Power BI, Azure Analysis Services, and Excel Power Pivot. DAX is a powerful language that can quickly empower you to analyze year-over-year or rolling 12 months calculations. It is rare to find an analytics solution using Microsoft technologies (especially Power BI) that doesn't require some calculations to be written by DAX. As a Power BI (or Microsoft BI) developer, it is essential to learn this language and master it. Learning a language is not just learning the structure and functions. It is learning how, where, and when to use it so that you can solve real-world problems with it. In my training and consulting experience on Power BI, I realized that DAX is the weak point for many Power BI users. DAX itself is not a complex language. It is merely a language of expression. The complexity of learning DAX is not the formula or the functions. It is how to use it in real-world scenarios and how it performs on a dataset or visual. I have been writing many blogs about DAX for many years. My blog articles are all coming from my experience working with Power BI. I found it helpful to compile them all in a book. Because my blog articles practically explain things, I thought it better to title it as a practical way of learning DAX by examples. Indeed, there are books, articles, and Microsoft documentation on how each function works where and how. However, learning these through an example would bring a new way of understanding it. A good analytics solution is a combined outcome of a good data model, good data preparation, and good analytics and calculations. I have written another book about the Basics of modeling in Power BI. This book is covering the calculation and DAX aspects of it. This book is for you if you are building a Power BI solution. Even if you are just visualizing the data, calculations are an essential part of analytics. You do need to have the calculation ready before visualizing it. This is not a book to explain every single function in DAX. The approach in this book is to have practical examples. Every chapter is based on real-world examples of using a combination of functions to solve a challenge. You can start from any chapter and finish at any chapter. The order of chapters suggested in this book is just a guideline to help you have a smooth flow of topics. Each chapter can be read without needing other chapters. Examples of this book are designed in a way that you can use the learning straight away in your Power BI file.

Download or read book Spam written by Finn Brunton and published by MIT Press. This book was released on 2015-01-30 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: What spam is, how it works, and how it has shaped online communities and the Internet itself. The vast majority of all email sent every day is spam, a variety of idiosyncratically spelled requests to provide account information, invitations to spend money on dubious products, and pleas to send cash overseas. Most of it is caught by filters before ever reaching an in-box. Where does it come from? As Finn Brunton explains in Spam, it is produced and shaped by many different populations around the world: programmers, con artists, bots and their botmasters, pharmaceutical merchants, marketers, identity thieves, crooked bankers and their victims, cops, lawyers, network security professionals, vigilantes, and hackers. Every time we go online, we participate in the system of spam, with choices, refusals, and purchases the consequences of which we may not understand. This is a book about what spam is, how it works, and what it means. Brunton provides a cultural history that stretches from pranks on early computer networks to the construction of a global criminal infrastructure. The history of spam, Brunton shows us, is a shadow history of the Internet itself, with spam emerging as the mirror image of the online communities it targets. Brunton traces spam through three epochs: the 1970s to 1995, and the early, noncommercial computer networks that became the Internet; 1995 to 2003, with the dot-com boom, the rise of spam's entrepreneurs, and the first efforts at regulating spam; and 2003 to the present, with the war of algorithms—spam versus anti-spam. Spam shows us how technologies, from email to search engines, are transformed by unintended consequences and adaptations, and how online communities develop and invent governance for themselves.

Download or read book Algorithms for Decision Making written by Mykel J. Kochenderfer and published by MIT Press. This book was released on 2022-08-16 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: A broad introduction to algorithms for decision making under uncertainty, introducing the underlying mathematical problem formulations and the algorithms for solving them. Automated decision-making systems or decision-support systems—used in applications that range from aircraft collision avoidance to breast cancer screening—must be designed to account for various sources of uncertainty while carefully balancing multiple objectives. This textbook provides a broad introduction to algorithms for decision making under uncertainty, covering the underlying mathematical problem formulations and the algorithms for solving them. The book first addresses the problem of reasoning about uncertainty and objectives in simple decisions at a single point in time, and then turns to sequential decision problems in stochastic environments where the outcomes of our actions are uncertain. It goes on to address model uncertainty, when we do not start with a known model and must learn how to act through interaction with the environment; state uncertainty, in which we do not know the current state of the environment due to imperfect perceptual information; and decision contexts involving multiple agents. The book focuses primarily on planning and reinforcement learning, although some of the techniques presented draw on elements of supervised learning and optimization. Algorithms are implemented in the Julia programming language. Figures, examples, and exercises convey the intuition behind the various approaches presented.
