About the talk

In the past five years, graph neural networks (GNNs) have emerged as a very powerful family of neural network architectures that operate directly on graph data structures. It is very powerful that GNNs model tasks at the level of a dataset’s (often) more natural graph representation, but the algorithms that enable this generate some side effects when it comes to scaling GNNs to large graphs. They are very memory- and compute-hungry models so going beyond benchmark datasets to real-world biology, physics, e-commerce and social network problems is challenging and will require researching and developing new techniques. Join us for a conversation with industry leading researchers from AWS, PayPal, and Intel Labs to discuss how they think about optimizing and scaling graph neural networks and what data scientists should know if they want to work with these models.

About speakers

Sasikanth Avancha
Senior Research Scientist at Intel Parallel Compute Labs
Eddie Mattia
Product Manager at SigOpt

For the last few years I have been working closely with SigOpt customers to help them design better Experiments and better optimize their models. Since we joined Intel one year ago my goals have pivoted to extending insights from these often heavily involved, custom projects and using them to build product features that empower data scientists to spend more of their time working on the tasks that are most important to them, like attending SigOpt conferences to learn about fancy new types of neural networks.
