Learning Objectives

  • Understand the basics of graphs/networks properties and analysis, including what can you use it for and how

  • Learn how to generate basic network types, and the most often encountered network models in real data. Next, discover the most informative network measures to understand network structures and behaviors

  • Extract and interpret information about real public social network data by building, analyzing and visualizing it to gain understanding about its structure and behaviors.

DIFFICULTY LEVEL: BEGINNER

Course Abstract

Networks, also known as graphs are one of the most crucial data structures in our increasingly intertwined world. Social friendship networks, the world-wide-web, financial systems, infrastructure (power grid, streets), etc. are all network structures. Knowing how to analyze the underlying network topology of interconnected systems can provide an invaluable skill in anyone’s toolbox. This tutorial will provide a hands-on guide on how to approach a network analysis project from scratch and end-to-end: how to generate, manipulate, analyze and visualize graph structures that will help you gain insight about relationships between elements in your data. You will learn how to detect communities in network to identify more densely interconnected subgroups used on social media platforms to detect social groups, and how to most effectively highlight them in a graph visualization. Analyzing a network from real data is crucial in understanding the patterns and behaviors of a real system. But often times you will need to build synthetic networks, which can serve as baseline models for your studies, or sometimes it becomes even more cost efficient to rely on synthetic networks instead of collecting large-scale data. In the last part of this course you will learn when, why and how to build synthetic networks.

Real-world applications

  • Social media platforms

    Network analysis and modeling is used by online social media companies (i.e. Facebook, Twitter) to study opinion formation and influencing in social networks. Graph-based methods are also used to suggest new contacts on the platform or to recommend new products to customers, based on the products their online friends are interested in.

  • Healthcare

    Contact tracing skills and the ability to analyze and model infectious disease spreads, are all essential applications of networks/graph, especially during the COVID-19 pandemic.

  • Infrastructure

    Graph-based analysis and modeling are crucial in solving transportation system optimization problems, such as optimizing power-grid systems, airline or ground traffic flow and determine shortest paths, the most cost-efficient routes between destinations (i.e. Google Maps).
