A Hybrid Framework for Spatial Interpolation: Merging Data-driven with Domain Knowledge
This work addresses spatial interpolation for researchers and practitioners by combining observational data with domain knowledge, though it appears incremental as it builds on existing methods.
The paper tackled the problem of spatial interpolation by integrating data-driven feature extraction with rule-assisted domain knowledge, resulting in a framework that captures more localized spatial features and enhances nonlinear estimation capabilities.
Estimating spatially distributed information through the interpolation of scattered observation datasets often overlooks the critical role of domain knowledge in understanding spatial dependencies. Additionally, the features of these data sets are typically limited to the spatial coordinates of the scattered observation locations. In this paper, we propose a hybrid framework that integrates data-driven spatial dependency feature extraction with rule-assisted spatial dependency function mapping to augment domain knowledge. We demonstrate the superior performance of our framework in two comparative application scenarios, highlighting its ability to capture more localized spatial features in the reconstructed distribution fields. Furthermore, we underscore its potential to enhance nonlinear estimation capabilities through the application of transformed fuzzy rules and to quantify the inherent uncertainties associated with the observation data sets. Our framework introduces an innovative approach to spatial information estimation by synergistically combining observational data with rule-assisted domain knowledge.
