Vecchia Approximations and Optimization for Multivariate Matérn Models
Youssef Fahmy, Joseph Guinness
We describe our implementation of the multivariate Matérn model for multivariate spatial datasets, using Vecchia's approximation and a Fisher scoring optimization algorithm. We con…
A Gaussian-process approximation to a spatial SIR process using moment closures and emulators
Parker Trostle, Joseph Guinness, Brian J. Reich
The dynamics that govern disease spread are hard to model because infections are functions of both the underlying pathogen as well as human or animal behavior. This challenge is in…
Comparison of CYGNSS and Jason-3 Wind Speed Measurements via Gaussian Processes
William Bekerman, Joseph Guinness
Wind is a critical component of the Earth system and has unmistakable impacts on everyday life. The CYGNSS satellite mission improves observational coverage of ocean winds via a fl…
Scalable Gaussian-process regression and variable selection using Vecchia approximations
Jian Cao, Joseph Guinness, Marc G. Genton +1
Gaussian process (GP) regression is a flexible, nonparametric approach to regression that naturally quantifies uncertainty. In many applications, the number of responses and covari…
