Abstract
Abstract This survey proposed a new methodology ‐ iGAEZ (improved GAEZ), developed based on the GAEZ (Global Agro‐Ecological Zones) model, capable of simulating crop yields on a global scale for wheat, potato, cassava, soybean, rice, sweet potato, maize, green beans. iGAEZ determines the optimum criteria of crop parameter of growth cycles to ensure best realistic crop yield combinations under comprehensive consideration of climate and crop condition. Global‐scale crop yields were calculated using iGAEZ model for the period of 1990‐1999. Through comparing simulated yields and FAO statistics, iGAEZ has demonstrated a very good ability to reproduce realistic crop yields on a global scale. We also predicted the impact of global warming on crop yields from the 1990s to 2090s by projecting five GCM outputs for AR4 under SRES A1B scenarios. According to the result, temperature rise will make many cultivated areas (eastern part of USA, India, eastern China, Africa) less productive. On the other hand, the regions with cold weather under current climate condition (Canada, northern Europe, northeastern China) become suitable for crop productivity under future climate scenario.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
