SECRET: A Scalable Linear Regression Tree Algorithm

SECRET (Scalable EM Classification-based Regression Trees) is a new construction algorithm for regression trees with linear models in the leaves. The algorithm produces regression trees with accuracy comparable to existing algorithms and at the same time requires far less computational effort on large datasets. Experimental results show that SECRET improves the running time of regression tree construction by up to two orders of magnitude compared to previous work while constructing trees of comparable quality.

Source Code Download

The SourceForge download page has instructions on downloading the initial alpha release of the code.

CVS access is also available:
