Practical Data Science Cookbook, Second Edition - Second Edition

Overview of this book

As increasing amounts of data are generated each year, the need to analyze and create value out of it is more important than ever. Companies that know what to do with their data and how to do it well will have a competitive advantage over companies that don’t. Because of this, there will be an increasing demand for people that possess both the analytical and technical abilities to extract valuable insights from data and create valuable solutions that put those insights to use. Starting with the basics, this book covers how to set up your numerical programming environment, introduces you to the data science pipeline, and guides you through several data projects in a step-by-step format. By sequentially working through the steps in each chapter, you will quickly familiarize yourself with the process and learn how to apply it to a variety of situations with examples using the two most popular programming languages for data analysis—R and Python.

Preface

Exploring subgraphs within a heroic network


The graph in the previous recipe, Importing networks, is much too large for us to get a feel for what is happening at the individual level, although we'll soon look at analyses that tell us interesting things about populations and communities. However, in order for us to see something interesting immediately, let's extract a subgraph to play with. In particular, we'll collect a subgraph for a particular hero in our dataset. When a subgraph is generated with a single person or actor as a focal point, it is called an ego network, and, in fact, the degree of an ego network might be a measure of an individual's self-worth!

Getting ready

As long as you completed the previous recipe, you will be prepared for this one.

How to do it...

The following steps will lead you through extracting subgraphs from our large dataset and visualizing the ego networks:

  1. Every social network has as many egos as nodes. The neighbors of an ego are called alters. The definition...
