Scoruby - Ruby scoring API for PMML files. Scoruby is a ruby gem that loads statistical models, gets their input, runs them, and returns the corresponding output. The gem loads its models from XML files in PMML format, which can be generated from different research environments among them R and Python open source packages. Scoruby implements the models scoring algorithms with data from the PMML files. We currently support Decision Trees, Random Forest and Gradient Boosted Models, and plan on keep adding models as we go.
