From the H2O homepage:
H2O is for data scientists and application developers who need fast, in-memory scalable machine learning for smarter applications. H2O is an open source parallel processing engine for machine learning. Unlike traditional analytics tools, H2O provides a combination of extraordinary math, a high performance parallel architecture, and unrivaled ease of use.
Videos and docs from two days of presentations on H2O.
I first saw this in Video: H2O Talks by Trevor Hastie and John Chambers by Joseph Rickert.
