Hashtag for R meetups: #pdxrlang




The discussion will begin with a brief overview of the current machine learning landscape in R. After the introduction, we will discuss H2O, a scalable open source machine learning library. H2O has APIs in R, Python, Scala and Java, and the focus of this talk will be the h2o and h2oEnsemble R packages. All of H2O's algorithm implementations are distributed, which allows the software to scale to big data. H2O can be used to speed up machine learning problems on your laptop (as a local multicore cluster), or it can be used in a multi-node cluster setting (for example, on Amazon EC2). H2O currently features distributed implementations of GLM, GBM, Random Forest and Deep Neural Nets. H2O.ai, the company behind H2O, is based in Mountain View, CA and has a scientific advisory council comprised of very well known contributors to machine learning community: Trevor Hastie, Rob Tibshirani and Stephen Boyd, all from Stanford University.
