Abstract

fetched live from OpenAlex

This paper presents a method to model fire growth over multiple time scales. These scales correspond to the confidence levels that can be placed in forecasted weather products, changing the model from deterministic to probabilistic as the range of the weather forecasts increases. Fire growth is modelled through the various stages in sequence, providing probability maps of potential fire extents. The short- range model predicts fire growth on an hourly scale using a deterministic, eight-point fire growth model. The medium-range model predicts fire growth over several days. This model uses the same fire-growth engine but introduces forecast reliability through the use of ensemble techniques. The long-range model predicts fire growth on a scale of weeks. This model combines the probabilities of fire spread and of sur- vival to produce a probable fire extent map. A case study of a large fire in Wood Buffalo National Park, Canada, is conducted to illustrate the use of the model.

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.
