New method scales geostatistical simulation using optimal transport

By PulseAugur Editorial · [1 sources] ·

Researchers have developed MST-Direct at Scale, an advancement in multivariate geostatistical simulation using optimal transport. This new method extends previous work to handle larger grids and multiple variables, while also incorporating conditional data. The approach uses a sparse Sinkhorn matcher for scalability and a Gaussian backbone to reproduce specified variograms, exactly preserving the multivariate joint distribution and honouring hard data.

IMPACT Enhances simulation capabilities for complex spatial data, potentially impacting fields like resource exploration and environmental modeling.

    MST-Direct at Scale: Multivariate and Conditional Geostatistical Simulation via Sinkhorn Optimal Transport

    arXiv:2606.07578v1 Announce Type: cross Abstract: This paper extends MST-Direct, a Matching-via-Sinkhorn-Transport approach for multivariate geostatistical simulation, from the original bivariate, unconditional, small-grid formulation to multivariate, conditional, and large-grid …
