This article examines the capability of Gaussian Process Regression (GPR), Generalized Regression Neural Network (GRNN) and Relevance Vector Machine (RVM) for prediction of Ground Water Table (dw) at Vellore (India). RVM, GRNN and GPR have been adopted as regression techniques. RVM is a probabilistic model. GRNN approximates any arbitrary function between input and output variables. GPR is a non-parametric model. The developed GPR, RVM and GRNN give the spatial variability of dw at Vellore. Map of dw has been also produced by the GPR, RVM and GRNN models. The results show that the developed RVM gives the best model for prediction of dw at Vellore.
