Exploratory Data Analysis with R

Editorial Reviews

This book covers some of the basics of visualizing data in R and summarizing high dimensional data with statistical multivariate analysis techniques. There is less of an emphasis on formal statistical inference methods, as inference is typically not the focus of EDA. Rather, the goal is to show the data, summarize the evidence and identify interesting patterns while eliminating ideas that likely won’t pan out.

Throughout the book, we will focus on the R statistical programming language. We will cover the various plotting systems in R and how to use them effectively. We will also discuss how to implement dimension reduction techniques like clustering and the singular value decomposition. All of these techniques will help you to visualize your data and to help you make key decisions in any data analysis.

Table of Contents

  • Getting Started with R
  • Managing Data Frames with the dplyr package
  • Exploratory Data Analysis Checklist
  • Principles of Analytic Graphics
  • Exploratory Graphs
  • Plotting Systems
  • Graphics Devices
  • The Base Plotting System
  • The ggplot2 Plotting System: Part 1

Data Mining for Business Intelligence, 2nd Edition

Editorial Reviews

Data Mining for Business Intelligence: Concepts, Techniques, and Applications in Microsoft Office Excel with XLMiner

Incorporating a new focus on data visualization and time series forecasting, Data Mining for Business Intelligence, Second Edition continues to supply insightful, detailed guidance on fundamental data mining techniques. This new edition guides readers through the use of the Microsoft Office Excel add-in XLMiner for developing predictive models and techniques for describing and finding patterns in data.
From clustering customers into market segments and finding the characteristics of frequent flyers to learning what items are purchased with other items, the authors use interesting, real-world examples to build a theoretical and practical understanding of key data mining methods, including classification, prediction, and affinity analysis as well as data reduction, exploration, and visualization.
The Second Edition now features:

  • Three new chapters on time series forecasting, introducing popular business forecasting methods including moving average, exponential smoothing methods; regression-based models; and topics such as explanatory vs. predictive modeling, two-level models, and ensembles
  • A revised chapter on data visualization that now features interactive visualization principles and added assignments that demonstrate interactive visualization in practice
  • Separate chapters that each treat k-nearest neighbors and Naïve Bayes methods
  • Summaries at the start of each chapter that supply an outline of key topics

The book includes access to XLMiner, allowing readers to work hands-on with the provided data. Throughout the book, applications of the discussed topics focus on the business problem as motivation and avoid unnecessary statistical theory. Each chapter concludes with exercises that allow readers to assess their comprehension of the presented material. The final chapter includes a set of cases that require use of the different data mining techniques, and a related Web site features data sets, exercise solutions, PowerPoint slides, and case solutions.
Data Mining for Business Intelligence, Second Edition is an excellent book for courses on data mining, forecasting, and decision support systems at the upper-undergraduate and graduate levels. It is also a one-of-a-kind resource for analysts, researchers, and practitioners working with quantitative methods in the fields of business, finance, marketing, computer science, and information technology.

Intelligent Knowledge: A Study beyond Data Mining

Editorial Reviews

This book is mainly about an innovative and fundamental method called “intelligent knowledge” to bridge the gap between data mining and knowledge management, two important fields recognized by the information technology (IT) community and business analytics (BA) community respectively. The book includes definitions of the “first-order” analytic process, “second-order” analytic process and intelligent knowledge, which have not formally been addressed by either data mining or knowledge management. Based on these concepts, which are especially important in connection with the current Big Data movement, the book describes a framework of domain-driven intelligent knowledge discovery. To illustrate its technical advantages for large-scale data, the book employs established approaches, such as Multiple Criteria Programming, Support Vector Machine and Decision Tree to identify intelligent knowledge incorporated with human knowledge. The book further shows its applicability by means of real-life data analyses in the contexts of internet business and traditional Chinese medicines.

Table of Contents

Chapter 1 Data Mining and Knowledge Management
Chapter 2 Foundations of Intelligent Knowledge Management
Chapter 3 Intelligent Knowledge and Habitual Domain
Chapter 4 Domain Driven Intelligent Knowledge Discovery
Chapter 5 Knowledge-incorporated Multiple Criteria Linear Programming Classifiers
Chapter 6 Knowledge Extraction from Support Vector Machines
Chapter 7 Intelligent Knowledge Acquisition and Application in Customer Churn
Chapter 8 Intelligent Knowledge Management in Expert Mining in Traditional Chinese Medicines

Description: Preface to the English edition This monograph Ten Lectur,es on
Statistical and Structural Pattern Recognition uncovers the close
relationship between various well known pattern recognition
problems that have so far been considered independent. These
relationships became apparent when formal procedures addressing not
only known prob­ lems but also their generalisations were
discovered. The generalised problem formulations were analysed
mathematically and unified algorithms were found. The book unifies
of two main streams ill pattern recognition-the statisti­ cal a11d
structural ones. In addition to this bridging on the uppermost

Image Super-Resolution and Applications (by Fathi E. Abd El-Samie, Mohiy M. Hadhoud, Said E. El-Khamy)


Author(s): Fathi E. Abd El-Samie, Mohiy M. Hadhoud, Said E. El-Khamy

ISBN-10: 1466557966
ISBN-13: 9781466557963
Language: English
Description:
This book is devoted to the issue of image
super-resolution—obtaining high-resolution images from single or
multiple low-resolution images. Although there are numerous
algorithms available for image interpolation and
super-resolution, there’s been a need for a book that establishes
a common thread between the two processes. Filling this need,
Image Super-Resolution and Applications presents image
interpolation as a building block in the super-resolution
reconstruction process.

Instead of approaching image interpolation as either a
polynomial-based problem or an inverse problem, this book breaks
the mold and compares… more…
