Then again, back to new releases with features, updates, and/or fixes as needed. The lifecycle of an app or software system (also known as SDLC) has several main stages: I highly recommend starting with this course. This course is taught by GraphSage author, Jurij Leskovec, himself. It has publicly available slides from lectures, along with well recommended readings. I think this course is a must if you want to grow your knowledge about Graph Neural Networks. 1) Stanford Course: CS224W Machine Learning with Graphs Here’s the list of best resources that you need to bookmark if you want to get hands-on practical experience in this field. Since the GNN field has been growing very quickly, up-to-date knowledge is not always easily available. Best learning resources for Graph Neural NetworksĪfter my first GNN article, I got a lot of messages asking for the best resources to understand this topic. If you use PyTorch, on the other hand, you can learn how to track your runs here. If you use TensorFlow/Keras for model training, check how you can keep track of this process here. If you want a fast, capable library at a relatively established and mature state of development, with the ease of integration of common benchmark datasets to implementation of other papers, then PyTorch Geometric is a good choice. At the same time, it’s a reasonable choice if you’re working on legacy projects. For Graph Nets DeepMind library, I don’t recommend starting a new GNN project with it due to TensorFlow 1. It’s about choosing the library that meets your needs, and this choice is usually influenced by a previous choice of deep learning libraries made by you or by your manager/teammate.įor example, if you’ve worked before, or you’re used to working with Keras and Tensorflow, then Spektral may be a good library for you. Unfortunately, there’s a trade-off for the simplicity of using Spektral, which is the slowness in training speeds for most tasks compared to other libraries like DGL and PyG. This library is designed according to the guiding principles of Keras to make things extremely simple for beginners while maintaining flexibility for experts. It implements some of the most popular layers for graph deep learning. You can use Spektral to classify the users of a social network, predict molecular properties, generate new graphs with GANs, cluster nodes, predict links, and any other task where data is described by graphs. The main goal of this library is to provide a simple, flexible framework for creating GNNs. Spektral is an open-source Python graph deep learning library, based on the Keras API and TensorFlow 2. A graph-wise prediction task could be predicting the chemical properties of molecular graphs. An edge-wise prediction task could be link prediction, a common scenario in recommender systems. For example, a prediction at a node level could solve a task like spam detection. GNNs are neural networks designed to make predictions at the level of nodes, edges, or entire graphs. They’re a class of deep learning models for learning on graph-structured data. Graph Neural Networks (GNNs) came to life quite recently. For a more in-depth understanding of GNN basics and applications, feel free to check out my previous article. Prerequisites: This article assumes a basic understanding of Machine Learning (ML), Deep Learning (DL), and GNNs. We’ll describe Graph Neural Networks (GNNs), cover popular GNN libraries, and we’ll finish with great learning resources to get you started in this field. This fuels the growing interest of deep learning researchers in the structure of graph data. Graphs have a lot of practical uses - in social networks, natural science (physics systems), chemistry, medicine, and many other research areas. Lots of learning tasks deal with graph data that have rich relationships and mutual dependency between objects. Graphs are a kind of data structure that models a set of objects (nodes) and their relationships (edges).
