A covariate-driven spatial deformation model for nonstationary GPs is created using Lie algebra velocity fields with truncated covariate interactions, supporting efficient estimation and prediction from limited sample pairs.
According to Lemma 1, the DoE path independence grants us the guar- antees that the base velocity fields commute: [๐๐, ๐๐] = 0 for all ๐ โ ๐
