A straightforward and engaging approach to Data Science that skips the jargon and focuses on the essentials. In the newly revised second edition of Data Smart: Using Data Science to Transform Information into Insight, accomplished data scientist and speaker Jordan Goldmeier delivers an approachable and conversational approach to data science using Microsoft Excel’s easily understood features. The author also walks readers through the fundamentals of statistics, machine learning and powerful Artificial Intelligence (AI) concepts, focusing on how to learn by doing. Data Science is the transformation of data using mathematics and statistics into valuable insights, decisions, and products. At the end of this book, I’ll show you how to implement what we’ve built in Excel in R. In fact, this follows my own path in building data science tools for companies. First, I would lay out my ideas in Excel. Use the spreadsheet as a way to validate my ideas and make sure I understand exactly what the algorithms do. Then, usually, when I’m ready, I move it to R or Python.

Discover the utility of your organization's data with Microsoft Power BI. In Beginning Power BI for Business Users: Learning to Turn Data into Insights, accomplished data professional and business intelligence expert Paul Fuller delivers an intuitive and accessible handbook for professionals seeking to use Microsoft's Power BI to access, analyze, understand, report, and act on the data available to their organizations. In the book, you'll discover Power BI's robust feature set, learn to ingest and model data, visualize and report on that data, and even use the DAX scripting language to unlock still more utility from Microsoft's popular program. Beginning with general principles geared to readers with no or little experience with reporting or data analytics tools, the author walks you through how to manipulate common, publicly available data sources—including Excel files and relational databases. As a data analytics engineer, I've loved using Power BI since it was introduced many years ago. But I'm a tech nerd. And many of the experts in Power BI are also geeks like me. But here's the thing—Power BI is meant to be a tool for business users and data analysts. It's intended to be simple enough to get started and see amazing things quickly but sophisticated enough that the information technology (IT) folks can use it as well.

Conduct impact measurement and outcomes evaluation, with a specific focus on nonprofits, using Salesforce Nonprofit Cloud (aka Salesforce for Nonprofits). As funding grows more challenging for nonprofits, having a robust technology system in place allows nonprofits to better seek out funding and receive more when they do. Readers of this book will be better positioned to ensure the long-term success of their organization and make maximum use of their technology. The book begins with an introduction to Salesforce and to Nonprofit Cloud for users who may be new to the platform. Next, you will learn the fundamentals of impact measurement and outcomes evaluation. You will understand why these are important and discover several frameworks that can be used to select outcomes that make sense for your organization to prove that its work is successful. These frameworks include Social Return on Investment (SROI), Cost-Benefit Analysis (CBA), and Pre and Post Comparison (and others). For Salesforce administrators, nonprofit staff members, and others working at nonprofits who are required to conduct impact measurement and outcomes evaluation.

Drone data analytics guarantee that the right people have the correct data at their fingertips whenever needed. Drone flight gathers a Terabyte of data and geo-tagged reference points without traditional ground control. The data automatically uploads to the aerial computing platform. Aerial computing analyzes the data and generates the required output in visualization, graph, and action. This book presents a comprehensive overview of Drone Data Analytics in Aerial Computing, exploring the latest techniques, tools, and technologies in this rapidly growing field. This book aims to provide readers with a comprehensive understanding of drone data analytics and aerial computing. It aims to bridge the gap between the technical and non-technical aspects, making it accessible and understandable to a wide range of readers. The world of AI and Data Science is changing fast, and so are its successor technologies. One of the latest additions to this stack is Federated analytics. Federated Learning (FL) is a way to train centralized Machine Learning models on decentralized data. A dominant application of Federated Learning has been In the medical sector, where data privacy and accuracy are of prime importance. Another application where Federated Learning can make a mark is federated analytics for drone technology.

This book presents the state-of-the-art in the emerging field of Data Science and includes models for layered security with applications in the protection of sites―such as large gathering places―through high-stake decision-making tasks. Such tasks include cancer diagnostics, self-driving cars, and others where wrong decisions can possibly have catastrophic consequences. The manipulability of aggregation procedures for the case of large numbers of voters is analyzed from a theoretical point of view and justified by computational experiments involving at least an order of magnitude larger number of voters. Many tree-type structures are considered: from phylogenetic trees representing the main patterns of vertical descent through consensus trees and super- trees widely used in evolutionary studies to combine phylogenetic information contained in individual gene trees. The statistical part of this book studies an impact of data mining and modeling on predictability assessment of time series. New notions of mean values based on ideas of multicriteria optimization are compared to their conventional definitions leading to fresh algorithmic approaches. To summarize, the book presents methods for automated analysis of patterns and models for data of different nature with applications ranging from scientific discovery to business intelligence and analytics. The style of the written chapters allows to recommend this book for senior undergraduate and graduate data mining courses providing a broad yet in-depth review integrating novel concepts from Machine Learning and statistics.
