Spatial Heterogeneity

Spatial heterogeneity, the uneven distribution of characteristics across space, is a central challenge in many scientific fields, demanding models that accurately capture and account for these variations. Current research focuses on developing and applying advanced machine learning techniques, including federated learning, geographically weighted regression (and its extensions), and deep neural networks, to address this heterogeneity in diverse applications such as environmental modeling, urban planning, and real estate valuation. These efforts aim to improve the accuracy and generalizability of predictive models by explicitly incorporating spatial context and addressing issues like data scarcity and privacy concerns. The resulting improvements in model performance have significant implications for various sectors, enabling more effective resource allocation, policy-making, and decision-support systems.
