CGaussianProcessMachine Class Reference

Detailed Description

A base class for Gaussian Processes.

Instead of a distribution over weights, the GP specifies a distribution over functions:

\[ f(x) \sim \mathcal{GP} (m(x), k(x,x')) \]

where \(m(x)\) - mean function, \(k(x, x')\) - covariance function.
