Hands-On Graph Neural Networks Using Python

By: Maxime Labonne

Overview of this book

Graph neural networks are a highly effective tool for analyzing data that can be represented as a graph, such as networks, chemical compounds, or transportation networks. The past few years have seen an explosion in the use of graph neural networks, with their application ranging from natural language processing and computer vision to recommendation systems and drug discovery. Hands-On Graph Neural Networks Using Python begins with the fundamentals of graph theory and shows you how to create graph datasets from tabular data. As you advance, you’ll explore major graph neural network architectures and learn essential concepts such as graph convolution, self-attention, link prediction, and heterogeneous graphs. Finally, the book proposes applications to solve real-life problems, enabling you to build a professional portfolio. The code is readily available online and can be easily adapted to other datasets and apps. By the end of this book, you’ll have learned to create graph datasets, implement graph neural networks using Python and PyTorch Geometric, and apply them to solve real-world problems, along with building and training graph neural network models for node and graph classification, link prediction, and much more.

Summary

In this chapter, we explored the use of GNNs for detecting anomalies in a new dataset, the CIDDS-001 dataset. First, we preprocessed the dataset and converted it into a graph representation, allowing us to capture the complex relationships between the different components of the network. We then implemented a heterogeneous GNN with GraphSAGE operators. It captured the heterogeneity of the graph and allowed us to classify the flows as benign or malicious.

The application of GNNs in network security has shown promising results and opened up new avenues for research. As technology continues to advance and the amount of network data increases, GNNs will become an increasingly important tool for detecting and preventing security breaches.

In Chapter 17, Recommending Books Using LightGCN, we will explore the most popular application of GNNs with recommender systems. We will implement a lightweight GNN on a large dataset and produce book recommendations for given users.
