spheroid90gp: Gaussian process emulation of vertical spheroidal elastic cavity models

The spheroid90gp software package computes surface displacements and cavity compressibility due to pressure or volume changes in buried vertical spheroidal elastic cavities. The software uses supervised machine learning techniques based on parallel partial Gaussian process emulators. The technique yields the accuracy of a numerical model at a computational cost comparable to that of some analytical models; it can also be utilized without finite element software, is suitable for a wide range of cavity geometries and depths, includes an estimate of uncertainties associated with emulation, and can be used to train new emulators for different source geometries.
