Description:

This toolbox (GPLP) is the Octave and Matlab implementation of several localized Gaussian process regression methods: the domain decomposition method [1], partial independent conditional [2], localized probabilistic regression [3], and bagging for Gaussian process regression [4]. Most of the localized regression methods can be applied for general machine learning problems although DDM is only applicable for spatial datasets. In addition, the GPLP provides two parallel computation versions of the domain decomposition method. The easiness of being parallelized is one of the advantages of the localized regression, and the two parallel implementations will provide a good guidance about how to materialize this advantage as software.

This toolbox is implemented in Matlab code such that it is executable and has been tested in Matlab Version 7.7 or later versions, and Octave Version 3.2.4 or later versions. It might be executable in any of Matlab Version 7.x and any of Octave Version 3.2.x, but it has not been tested on those versions.
