We introduce the mixture of Gaussian processes (MGP) model which is
useful for applications in which the optimal bandwidth of a map is input
dependent. The MGP is derived from the mixture of experts model and
can also be used for modeling general conditional probability densities.
We discuss how Gaussian processes -in particular in form of Gaussian
process classification, the support vector machine and the MGP modelcan
be used for quantifying the dependencies in graphical models.
