abstract = "This study adopts four modeling techniques Ordinary
Kriging (OK), Generalized Regression Neural Network
(GRNN), Genetic Programming (GP) and Minimax
Probability Machine Regression (MPMR) for prediction of
rock depth (d) at Chennai, India. Latitude (Lx) and
Longitude (Ly) have been used as inputs of the models.
A semivariogram has been constructed for developing the
OK model. The developed GP gives equation for
prediction of d at any point in Chennai. A comparison
of four modeling techniques has been carried out. The
performance of MPMR is slightly better than the other
models. The developed models give the spatial
variability of rock depth at Chennai.",
