Scalable Automatic Machine Learning in R with H2O

Dr. Erin LeDell is the Chief Machine Learning Scientist at H2O.ai, where she leads the development of an open-source, automatic machine learning (AutoML) platform. Before joining H2O.ai, she worked as a data scientist and software engineer and founded DataScientific, Inc. She’s also the founder of the non-profit Women in Machine Learning & Data Science (WiMLDS.org) organization and co-founder of the R-Ladies Global organization. The focus of this presentation is scalable and automatic machine learning in R using the H2O machine learning platform.

H2O is an open-source, distributed machine learning platform is designed to scale to very large datasets that may not fit into RAM on a single machine. We will provide a brief overview of the field of Automatic Machine Learning, followed by a detailed look inside H2O’s AutoML algorithm. H2O AutoML provides an easy-to-use interface that automates data pre-processing, training and tuning a large selection of candidate models (including multiple stacked ensemble models for superior model performance), and due to the distributed nature of the H2O platform, H2O AutoML can scale to very large datasets.

The result of the AutoML run is a “leaderboard” of H2O models which can be easily exported for use in production. R code examples are available on GitHub for participants to follow along on their laptops. A local chapter of R-Ladies Global, R-Ladies Edinburgh exists to promote gender diversity in the R community worldwide. We are pro-actively inclusive of queer, trans, and all minority identities, with additional sensitivity to intersectional identities.

Our priority is to provide a safe community space for anyone identifying as a minority gender who is interested in and/or working with R. As a founding principle, there is no cost or charge to participate in any of our R-Ladies communities around the world. R-Ladies events are open to all, however if you do not identify as a minority gender, we ask that you come along as the guest of someone who does.

Please review our code of conduct before attending the event.
