- Regression tree package: contains a c implementation of (multiple output) regression trees and various ensemble methods thereof, including extremely randomized trees (Geurts et al., 2006), Random Forests (Breiman, 2001), and multiple additive regression trees (Friedman et al.). The c code is not standalone but a matlab interface is also included. This code is also used in the GENIE3 software for gene regulatory network inference and in Lucian Busoniu's matlab approximate reinforcement learning toolbox.
