Überprüfen, ob ein Graph gerichtet/ungerichtet ist

Im Video hat Eric dir verschiedene Arten von Graphen vorgestellt. Welchem Typ entspricht deiner Meinung nach das Twitter-Netzwerk, mit dem du gearbeitet hast? Nutze die eingebaute Python-Funktion type() in der IPython-Shell, um es herauszufinden. Das Netzwerk wurde wie zuvor als T vorab geladen.

Welche der vier Optionen unten entspricht dem Graph-Typ von T?

In this chapter, you'll be introduced to fundamental concepts in network analytics while exploring a real-world Twitter network dataset. You'll also learn about NetworkX, a library that allows you to manipulate, analyze, and model graph data. You'll learn about the different types of graphs and how to rationally visualize them.

Exercise 1: Einführung in Netzwerke Exercise 2: Was ist ein Netzwerk?Exercise 3: Grundlagen der NetworkX-API am Twitter-Netzwerk Exercise 4: Einfaches Zeichnen eines Netzwerks mit NetworkX Exercise 5: Abfragen in einem Graphen Exercise 6: Arten von Graphen Exercise 7: Überprüfen, ob ein Graph gerichtet/ungerichtet ist

You'll learn about ways to identify nodes that are important in a network. In doing so, you'll be introduced to more advanced concepts in network analysis as well as the basics of path-finding algorithms. The chapter concludes with a deep dive into the Twitter network dataset which will reinforce the concepts you've learned, such as degree centrality and betweenness centrality.

This chapter is all about finding interesting structures within network data. You'll learn about essential concepts such as cliques, communities, and subgraphs, which will leverage all of the skills you acquired in Chapter 2. By the end of this chapter, you'll be ready to apply the concepts you've learned to a real-world case study.

Exercise 1: Communities & cliques Exercise 2: Identifying triangle relationships Exercise 3: Finding nodes involved in triangles Exercise 4: Finding open triangles Exercise 5: Maximal cliques Exercise 6: Finding all maximal cliques of size "n"Exercise 7: Subgraphs Exercise 8: Subgraphs I Exercise 9: Subgraphs II

In this final chapter of the course, you'll consolidate everything you've learned through an in-depth case study of GitHub collaborator network data. This is a great example of real-world social network data, and your newly acquired skills will be fully tested. By the end of this chapter, you'll have developed your very own recommendation system to connect GitHub users who should collaborate together.
