Stream Kriging: Incremental and recursive ordinary Kriging over spatiotemporal data streams

Computers and Geosciences, 2016
Ordinary Kriging is widely used for geospatial interpolation and estimation. Due to the O(n3) time complexity of solving the system of linear equations, ordinary Kriging for a large set of source points is computationally intensive. Conducting real-time Kriging interpolation over continuously varying spatiotemporal data streams can therefore be ...

Can regression determination, nugget-to-sill ratio and sampling spacing determine relative performance of regression kriging over ordinary kriging?

Catena, 2019
Regression kriging (RK), a popular digital soil mapping method which combines regression and ordinary kriging (OK) to predict, did not always perform better than OK purely.

Comparing the robustness of ordinary kriging and lognormal kriging: Outlier resistance

Mathematical Geosciences, 1988
Ordinary kriging is well-known to be optimal when the data have a multivariate normal distribution (and if the variogram is known), whereas lognormal kriging presupposes the multivariate lognormality of the data. But in practice, real data never entirely satisfy these assumptions.

Ordinary Kriging Surrogates in Aerodynamics

Uncertainty Management for Robust Industrial Design in Aeronautics, 2018
This chapter describes the methodology used to construct Kriging-based surrogate models and their possible application to uncertainty quantification and robust shape optimization. More particularly, a two-dimensional RAE 2822 airfoil at transonic speed is considered for which the shape of the baseline profile is altered by localized bumps of small ...

Assessing uncertainty in estimates with ordinary and indicator kriging

Computers and Geosciences, 2001
The objective of this paper is to examine the applicability of three geostatistical approaches, ordinary kriging (OK), kriging with a trend model (KT), and indicator kriging (IK), to the assessment of uncertainty in estimates. This paper uses the OK and KT standard error and the conditional standard error of the conditional cumulative distribution ...

Strain estimation using ordinary Kriging interpolation

Survey Review, 2016
The ordinary kriging interpolation method is adopted to estimate the 2-D strain tensor elements. The results are then compared with those of the linear and spline interpolation methods. The ordinary kriging method is implemented on 12 GPS permanent stations in South California, collected during 2006 to 2012.

Ordinary-Kriging Based Real-Time Seizure Detection in an Edge Computing Paradigm

IEEE International Conference on Consumer Electronics, 2020
To best of the authors’ knowledge, this is the first work that uses Kriging for early detection of seizure. The threat of an epileptic seizure to the life of a patient is both social and physical.
