Distributed Learning of Rule Ensemble Models with H2O

Rule Ensembles (RE) refer to an ensemble-based model built by combining simple, readable rules. While maintaining (and often improving) the accuracy of the classic tree ensemble, the rule-based model is much more interpretable. In this talk, I present an overview of REs and demo H2O-REgo, an R-based package that enables distributed learning of REs models on very large data sets using H2O.
