Abstract

fetched live from OpenAlex

Current urban climate projections typically assume static urban morphology, potentially overlooking the significant impact of evolving built environments on local climate patterns. This methodological limitation introduces uncertainties in long-term climate assessments, particularly in rapidly developing urban areas. We present a novel approach using a conditional diffusion model, specifically flow matching, to predict future urban morphological changes based on projected land use patterns. Our methodology leverages existing research on land use change prediction as conditional inputs to generate detailed morphological evolution scenarios, including building heights, densities, and spatial configurations. The projected land use maps incorporate both local urban planning constraints and broader development patterns to ensure realistic predictions. Initial results demonstrate the model's capability to generate physically plausible urban morphologies that maintain consistency with projected land use changes while preserving local architectural characteristics. The predictions show promising accuracy in replicating historical morphological transitions, suggesting potential applicability in future scenario modeling. By introducing dynamic morphology predictions into urban climate modeling, our approach enables more comprehensive assessment of future urban climate conditions. This research bridges a critical gap between urban development forecasting and climate projection models, providing urban planners and climatologists with improved tools for adaptive planning. The integration of morphological evolution in climate projections represents a significant advancement in understanding the complex interactions between urban form and local climate patterns, particularly in the context of rapid urbanization and climate change.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
