Abstract

fetched live from OpenAlex

The variation of the normalized difference vegetation index(NDVI) and its relationship with precipitation,air temperature,and sunshine duration in the Jialing River Basin during the period from 1982 to 2006 were studied using statistical methods.The results show that the annual average NDVI had an increasing trend during the study period,especially in the spring,and it was highly correlated with temperature.In all seasons,there was a lag in the change of the seasonal average NDVI when the air temperature and precipitation changed in the basin,especially in the vegetation growth seasons: spring,summer,and autumn.In the spring,the relationships between the average NDVI and the sunshine duration in the present quarter and the air temperature in the previous quarter were more significant.During the summer,the average NDVI was significantly influenced by meteorological factors of both the present quarter and the previous quarter.During the autumn,the average NDVI was significantly correlated with sunshine duration and was greatly influenced by the air temperature in the previous quarter.

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.
