Use popular data mining techniques in Microsoft Excel to better understand machine learning methods. Most software tools and programming language packages take data input and deliver data mining results directly, presenting no insight on working mechanics and creating a chasm between input and output. This is where Excel can help, and this book will show you exactly how. This updated edition demonstrates how to work with data in a transparent manner using Excel. When you open an Excel file, data is visible immediately and you can work with it directly. You’ll see how to examine intermediate results even as you are still conducting your mining task, offering a deeper understanding of how data is manipulated, and results are obtained. These are critical aspects of the model construction process that are often hidden in software tools and programming language packages. Anyone who is interested in learning data mining or Machine Learning, especially data science visual learners and people skilled in Excel who would like to explore Data Science topics and/or expand their Excel skills. A basic or beginner level understanding of Excel is recommended.

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.

Название: Data Analysis and Optimization: In Honor of Boris Mirkin's 80th Birthday
Автор: Boris Goldengorin, Sergei Kuznetsov
Издательство: Springer
Год: 2023
Страниц: 447
Язык: английский
Формат: pdf (true)
Размер: 14.7 MB

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.
