Book Description

Practical Graph Analytics with Apache Giraph helps you build data mining and machine learning applications using the Apache Foundation’s Giraph framework for graph processing. This is the same framework as used by Facebook, Google, and other social media analytics operations to derive business value from vast amounts of interconnected data points. Graphs arise in a wealth of data scenarios and describe the connections that are naturally formed in both digital and real worlds. Examples of such connections abound in online social networks such as Facebook and Twitter, among users who rate movies from services like Netflix and Amazon Prime, and are useful even in the context of biological networks for scientific research. Whether in the context of business or science, viewing data as connected adds value by increasing the amount of information available to be drawn from that data and put to use in generating new revenue or scientific opportunities. Apache Giraph offers a simple yet flexible programming model targeted to graph algorithms and designed to scale easily to accommodate massive amounts of data. Originally developed at Yahoo!, Giraph is now a top top-level project at the Apache Foundation, and it enlists contributors from companies such as Facebook, LinkedIn, and Twitter. Practical Graph Analytics with Apache Giraph brings the power of Apache Giraph to you, showing how to harness the power of graph processing for your own data by building sophisticated graph analytics applications using the very same framework that is relied upon by some of the largest players in the industry today.

Book Description

This book takes its reader on a journey through Apache Giraph, a popular distributed graph processing platform designed to bring the power of big data processing to graph data. Designed as a step-by-step self-study guide for everyone interested in large-scale graph processing, it describes the fundamental abstractions of the system, its programming models and various techniques for using the system to process graph data at scale, including the implementation of several popular and advanced graph analytics algorithms. The book is organized as follows: Chapter 1 starts by providing a general background of the big data phenomenon and a general introduction to the Apache Giraph system, its abstraction, programming model and design architecture. Next, chapter 2 focuses on Giraph as a platform and how to use it. Based on a sample job, even more advanced topics like monitoring the Giraph application lifecycle and different methods for monitoring Giraph jobs are explained. Chapter 3 then provides an introduction to Giraph programming, introduces the basic Giraph graph model and explains how to write Giraph programs. In turn, Chapter 4 discusses in detail the implementation of some popular graph algorithms including PageRank, connected components, shortest paths and triangle closing. Chapter 5 focuses on advanced Giraph programming, discussing common Giraph algorithmic optimizations, tunable Giraph configurations that determine the system’s utilization of the underlying resources, and how to write a custom graph input and output format. Lastly, chapter 6 highlights two systems that have been introduced to tackle the challenge of large scale graph processing, GraphX and GraphLab, and explains the main commonalities and differences between these systems and Apache Giraph. This book serves as an essential reference guide for students, researchers and practitioners in the domain of large scale graph processing. It offers step-by-step guidance, with several code examples and the complete source code available in the related github repository. Students will find a comprehensive introduction to and hands-on practice with tackling large scale graph processing problems using the Apache Giraph system, while researchers will discover thorough coverage of the emerging and ongoing advancements in big graph processing systems.

Book Description

“If young adults could be guided in the right direction for a life journey of meaning and purpose, we would be grooming the leaders of tomorrow for a better world. This book is the perfect guide.” —Deepak Chopra, MD, FACP, founder of the Chopra Center for Wellbeing What am I going to do for the rest of my life? This question is familiar for young people at a turning point—whether it’s facing the end of high school, college, graduate school, or just a dead-end job. Maybe they have the degree they want but don’t know where to start their job search. Perhaps they’re still choosing a major and, given the range—from “Biochemistry” to “Adventure Education”—are lost in the options. Maybe they’re facing a mountain of debt but don’t want to get locked into a job they hate. While other books might advise writing resumes or preparing for interviews, they only go so far. Young people want more than just another job—they want a life, and a meaningful one at that. Enter The Big Picture. Created by the leading authority on self-help research and reviewed by over six hundred college students, Dr. Christine B. Whelan’s The Big Picture offers a guide to discovering one’s talents, dreams, and desires that can lead one to a fulfilling career but fulfilling life. It guides young people to take a step back and look at the “big picture” of who they are, what they want, and why they’re here. Through quizzes and questionnaires which college students have vetted, Whelan guides the reader through “big picture” questions like, What are my talents—and how can I use those to help others and create meaning? How have my life experiences shaped who I am and what I can give? What do I value—and how can I be happy while being true to those values? Although there are endless books on finding a job, this is the first book that presents research-based and tested material to help young people answer the question, What will I do with my life? The Big Picture provides the resources needed to find—and live—a purposeful life. An excellent gift for a graduate or a guide for yourself.

Book Description

This book presents extensive research on two main problems in robotics: the path planning problem and the multi-robot task allocation problem. It is the first book to provide a comprehensive solution for using these techniques in large-scale environments containing randomly scattered obstacles. The research conducted resulted in tangible results both in theory and in practice. For path planning, new algorithms for large-scale problems are devised and implemented and integrated into the Robot Operating System (ROS). The book also discusses the parallelism advantage of cloud computing techniques to solve the path planning problem, and, for multi-robot task allocation, it addresses the task assignment problem and the multiple traveling salesman problem for mobile robots applications. In addition, four new algorithms have been devised to investigate the cooperation issues with extensive simulations and comparative performance evaluation. The algorithms are implemented and simulated in MATLAB and Webots.
