A Geostatistical Heterogeneity Metric for Spatial Feature Engineering

چکیده
Abstract Heterogeneity is a vital spatial feature for subsurface resource recovery predictions, such as mining grade tonnage functions, hydrocarbon factor, and water aquifer draw-down predictions. Feature engineering presents the opportunity to integrate heterogeneity information, but traditional engineered features like Dykstra-Parsons Lorenz coefficients ignore context; therefore, are not sufficient quantify over multiple scales of intervals inform predictive machine learning models. We propose novel use dispersion variance spatial-engineered that accounts within context, including continuity sample data model volume support size improve machine-learning-based models, e.g., pre-drill prediction uncertainty quantification. Dispersion generalized form can be calculated from semivariogram-based model. demonstrate useful predictor case prediction, with ability variation production well drainage radius, given variogram trajectory well. include synthetic example based on geostatistical models flow simulation show sensitivity production. Then we an informative forecasting field study in Duvernay formation.

Geostatistical Analysis of Spatial Data
First, geostatistics provides descriptive tools such as semivariograms to characterize the spatial pattern of continuous and categorical soil attributes. Various interpolation (kriging) techniques capitalize on the spatial correlation between observations to predict attribute values at unsampled locations using information related to one or several attributes. An important contribution of geost...
متن کاملSpatial heterogeneity of parasite co-infection: Determinants and geostatistical prediction at regional scales
Multiple parasite infections are widespread in the developing world and understanding their geographical distribution is important for spatial targeting of differing intervention packages. We investigated the spatial epidemiology of mono- and co-infection with helminth parasites in East Africa and developed a geostatistical model to predict infection risk. The data used for the analysis were ta...
متن کاملA Geostatistical Framework for Area-to-Point Spatial Interpolation
The spatial prediction of point values from areal data of the same attribute is addressed within the general geostatistical framework of change of support; the term support refers to the domain informed by each datum or unknown value. It is demonstrated that the proposed geostatistical framework can explicitly and consistently account for the support differences between the available areal data...
متن کاملFeature Engineering in Persian Dependency Parser
Dependency parser is one of the most important fundamental tools in the natural language processing, which extracts structure of sentences and determines the relations between words based on the dependency grammar. The dependency parser is proper for free order languages, such as Persian. In this paper, data-driven dependency parser has been developed with the help of phrase-structure parser fo...
