What is the subject of your talk going to be at the ML Summit?**\n\n\nI am going to talk about how deep graph neural networks (GNNs) are used to develop machine learning models for solving problems on domains where the underlying data is represented through graphs.\n\n<video src=\\"https://dev-media.amazoncloud.cn/d23d8a7cba114595be52c0bfc01909e4_Learning%20Graph%20Neural%20Networks%20with%20Deep%20Graph%20Library%20%EF%BC%8D%20www2020%20tutorial.mp4\\" class=\\"manvaVedio\\" controls=\\"controls\\" style=\\"width:160px;height:160px\\"></video>\n\n#### **Learning graph with neural networks - The Web Conference 2020**\n\n\nThe adoption of GNNs has exploded in recent years, as data scientists move from developing deep learning models for two-dimensional signals, such as images, and three-dimensional images, such as video, to learning from structured and related data embedded in graphs.\n\nAt Amazon, my team has been working on the [Deep Graph Library](https://www.amazon.science/videos-webinars/learning-graph-neural-networks-with-deep-graph-library) (DGL), an easy-to-use, high-performance and scalable Python package for deep learning on graphs. DGL is a framework that allows developers to program graph neural networks. DGL supplements existing tensor-based frameworks such as Tensorflow, PyTorch, and MXNet. During my talk, I’m going to talk about how DGL can be used to make the development, training, and use of GNNs easy and scalable.\n\n\n#### **Q. Why is this topic especially relevant within the science community today?**\n\n\n#### **There are a variety of problems for which we can develop accurate machine learning solutions by leveraging the linked data that is inherent to graphs.**\n\n\nGeorge Karypis\n\nGNNs are used in a number of fields today. For example, they play an increasingly important role in social networks, where graphs show connections among related people.\n\nWe have organizations like Marinus Analytics using GNNs to [help victims of human trafficking](https://www.amazon.science/latest-news/how-marinus-analytics-uses-knowledge-graphs-powered-by-aws-neptune-to-combat-human-trafficking).

At Amazon, they are used to develop recommender systems, build mechanisms for fraud and abuse detection, and develop Alexa's conversational capabilities, among other applications.\n\nThere are a variety of problems for which we can develop accurate machine learning solutions by leveraging the linked data that is inherent to graphs.\n\nGNNs are increasingly delivering state-of-the-art results in graph learning on a wide-range of domains. They are now one of the most actively researched areas in deep learning, even as we transition from academic and industrial research to actively powering products and services.\n\n\n#### **Q.
