This workshop will provide an overview of how to use H2O, the scalable open source machine learning library, from Python. The core algorithms of H2O are implemented in Java, however, fully-featured APIs are available in R, Python, Scala, and also through a web interface. The focus of this hands-on workshop will be the "h2o" Python module.

All of H2O's algorithm implementations are distributed, which allows the software to scale to large datasets that may not fit into RAM on a single machine. H2O currently features distributed implementations of Generalized Linear Models, Gradient Boosting Machines, Random Forest and Deep Neural Nets. In this workshop, attendees will learn how to train machine learning models, perform grid search, cross-validation, and evaluate model performance using the H2O Python API.

Pre-requisites: please bring a laptop.
