Abstract

fetched live from OpenAlex

In a workshop sponsored by the Natural Resources Group (NRG) of the International Maize and Wheat Improvement Center (CIMMYT), scientists from the USA, Canada, South Africa and CIMMYT gathered at CIMMYT headquarters during 19-22 April, 1999, to examine the performance of leading maize and wheat simulation models, particularly CERES, for tropical environments of high and low yield potentials. Major outcomes are reported in this publication and include: * revision of temperature effects on development in CERES Wheat 3.5; * examination of strategies for modeling barrenness and prolificacy in maize; * identification of the temperature effect on radiation use efficiency as a priority for subsequent revision; * heightened recognition of the need to compile quality data sets for maize and wheat growth from diverse environments.

Full frame distilled prediction

Teacher imitation

Not 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.
