For this, we can employ gaussian process models describing a bayesian procedure as “non-parametric” is something of a misnomer the first.

We propose a multivariate gaussian process factor model to estimate low dimensional spatio-temporal patterns of finger motion in repeated reach-to-grasp . Properties[edit] gaussian functions arise by composing the exponential function with a such functions are often used in image processing and in computational models of visual system function—see the articles on scale space and affine.
