Sketching data and other magic tricks
Who is this presentation for?machine learning practitioners, data scientists, data engineers, developers
What if we told you that you could answer interesting queries about truly massive data sets almost instantly and with a fixed amount of space? You might say that it sounds like magic. In this hands-on workshop, we’ll introduce several sketching data structures that work this magic and show you the key trick that makes them possible. We’ll introduce truly scalable techniques for several fundamental problems like set membership, set and document similarity, counting kinds of events, and counting distinct elements. You’ll learn how and when to use these structures as well as how they work. You’ll see how the same techniques work for parallel, distributed, and stream processing at scale. Finally, you’ll see how you can put these techniques to work in real data engineering and machine learning applications like join processing, document classification, and content personalization.

What you'll learn
Sophie Watson is a software engineer in an Emerging Technology Group at Red Hat, where she applies her data science and statistics skills to solving business problems and informing next-generation infrastructure for intelligent application development. She has a background in mathematics and holds a PhD in Bayesian statistics, in which she developed algorithms to estimate intractable quantities quickly and accurately.
William Benton leads a team of data scientists and engineers at Red Hat, where he has also applied machine learning to problems ranging from forecasting cloud infrastructure costs to designing better cycling workouts. His current focus is investigating the best ways to build and deploy intelligent applications in cloud-native environments, but he has also conducted research and development in the areas of static program analysis, managed language runtimes, logic databases, cluster configuration management, and music technology.
