gaussian process classification in r

A method for large scale Gaussian process classification has been recently proposed based on expectation propagation (EP). See Ras-mussen and Williams [2006] for a review. Many Gaussian process packages are available in R. For example there is $\textbf{BACCO}$ that offers some calibration techniques, $\textbf{mlegp}$ and $\textbf{tgp}$ focusing on treed models and parameter estimation and $\textbf{GPML}$ for Gaussian process classification and regression.

Recall that a gaussian process is completely specified by its mean function and covariance (we usually take the mean equal to zero, although it is not necessary). gpR shows how the calculation of the posterior predictive of a Gaussian Process and prediction of novel data is done when the kernel parameters are known. We demonstrate greatly improved image classification performance compared to current Gaussian process approaches on the MNIST and CIFAR-10 datasets. Their greatest practical advantage is that they can give a reliable estimate of their own uncertainty.
