This extension allows analysts to use the Octave language to build new operators in RapidMiner processes. It relies on a configurable pool of GNU Octave interpreters to handle concurrent access. It integrates in RapidAnalytics to schedule processes or provide them as RESTful web services. This extension relies on JavaOctave, a project to bridge java with Octave (http://kenai.com). Note: it can be downloaded directly through Rapid-I marketplace : http://rapidupdate.de:8180.
