WebJun 1, 2010 · Whereas SSGP relies on a sparse approximation to the spectrum, the FITC approximation is sparse. in a spatial sense: A set of pseudo-inputs is used as an information bottleneck. WebFITC approximation: the most widely used method for sparse GPs. The evaluations f of the function are conditionally independent given the value u of the function at the m inducing points: p(fju) ˇp~(fju) = Yn i=1 N(f ijK f i;uK 1 uu u;k f if i K f iuK 1 uu K uf i): The values u at the inducing points are the parameters of the sparse GP.
