From graph analytics to graph neural networks: Making the most of your graph data

Many powerful machine learning algorithms—including PageRank (Pregel), recommendation engines (collaborative filtering), and text summarization and other NLP tasks—are based on graphs. And there are even more applications once you consider data preprocessing and feature engineering, which are both vital tasks in machine learning pipelines.

Join expert Jörg Schad to explore the symbiosis of graphs and machine learning, starting with graph analytics to graph neural networks. You’ll learn why graphs are such a powerful abstraction and discover how to leverage them in your machine learning projects.

What you’ll learn and how you can apply it

By the end of this live online course, you’ll understand:

  • Why graphs are such a powerful abstraction
  • How to leverage knowledge graphs
  • The graph ecosystem including its many many powerful open source tools
  • How to extract value from graphs using graph analytics and graph algorithms
  • How to combine deep learning and graphs
  • How we can learn graphs features using graph neural networks

And you’ll be able to:

  • Identify suitable graph use cases
  • Use open source tools to create, manipulate, and query graphs
  • Leverage graph algorithms to analyze graphs
  • Apply machine learning techniques on graphs
  • Utilize the latest graph neural network techniques

This live event is for you because...

  • You’re a data scientist who wants to extend your toolset.
  • You’re a technical leader or architect who wants to understand the power of graphs and machine learning.
  • You’re an engineer who wants to learn about graphs and machine learning.
