Gaussian Processes Papers and Software

by Mark Gibbs

This page contains two papers on Gaussian processes. The first paper (gpros.ps.gz) gives a full introduction to the use of Gaussian processes and a discussion of their application to regression problems. It also details approximate matrix inversion methods that can be used to implement Gaussian process regression efficiently. The second paper (class.ps.gz) describes how Gaussian processes can be applied to binary classification problems.

Please feel free to download either of these papers. Any feedback (errors or suggestions for improved clarity) would be warmly received.

Also available is my thesis (thesis.ps.gz, thesis.ps). This discusses both regression and classification using Gaussian processes, details efficient implementations and tackles some interesting real-world problems. It is substantially more up-to-date and more detailed than the previous papers.

Gaussian Processes Software

Please read the following BEFORE downloading any of the software or documentation.

The Tpros Regression package is ONLY available for academic purposes. It is not available for industrial or commercial applications of any kind without explicit arrangement with the authors. Academic users may download the software and should send an email with the title ''Tpros Package'' or ''Cpros Package'' to

mng10@mrao.cam.ac.uk, mackay@mrao.cam.ac.uk

Please include the name of the academic institution at which the software will be used in the e-mail.

The software must not be posted on any WWW or ftp sites or distributed in any other way without prior permission of the authors.

The Software

Both tar files contain documentation describing how to install and use the software.

On downloading the Tpros.tar.gz file,

 gunzip  Tpros.tar.gz
 tar xvf Tpros.tar.gz
then read the file TManual. You may also find David MacKay's GP page helpful. Tpros Users may also find helpful the document: gpaus_manual and the other files in this directory. gpaus_manual describes how Tpros was used on an example modelling problem.
