A Global-Local Approximation Framework for Large-Scale Gaussian Process Modeling
Akhil Vakayil, Roshan Joseph
In this work, we propose a novel framework for large-scale Gaussian process (GP) modeling. Contrary to the global, and local approximations proposed in the literature to address th…
Data Twinning
Akhil Vakayil, V. Roshan Joseph
In this work, we develop a method named Twinning, for partitioning a dataset into statistically similar twin sets. Twinning is based on SPlit, a recently proposed model-independent…
SPlit: An Optimal Method for Data Splitting
V. Roshan Joseph, Akhil Vakayil
In this article we propose an optimal method referred to as SPlit for splitting a dataset into training and testing sets. SPlit is based on the method of Support Points (SP), which…
