A representation of a gaussian process, which is only defined on a discrete domain. While this is technically similar to a MultivariateNormalDistribution, we highlight with this class that we represent (discrete) functions, defined on the given domain.

Represents a low-rank gaussian process, that is only defined at a finite, discrete set of points. It supports the same operations as the LowRankGaussianProcess class, but always returns instead a discrete representation. Furthermore, most operations are much more efficient, as they are implemented using fast matrix/vector operations.

Where the modeled functions in a LowRankGaussianProcess are of type Point[D]=>Vector[D], this discretized version is of type VectorPointData.

It is possible to convert a DiscreteLowRankGaussianProcess to a LowRankGaussianProcess by calling the interpolation method.

A gaussian process from a D dimensional input space, whose input values are points, to a DO dimensional output space. The output space is a Euclidean vector space of dimensionality DO.

Factory methods for creating Gaussian processes

A gaussian process which is represented in terms of a (small) finite set of basis functions. The basis functions are the orthonormal basis functions given by a mercers' decomposition.

Factory methods for creating Low-rank gaussian processes, as well as generic algorithms to manipulate Gaussian processes.

Strategies for working with NaNValues.

A StatisticalMeshModel is isomorphic to a DiscreteLowRankGaussianProcess. The difference is that while the DiscreteLowRankGaussianProcess models defomation fields, the StatisticalMeshModel applies the deformation fields to a mesh, and warps the mesh with the deformation fields to produce a new mesh.
