Abstract

fetched live from OpenAlex

Using photographic observation data of grassland phenology over the entire growing season and different satellite remote sensing data in Xilinguole of Inner Mongolia,we analyzed statistical relationships between the two datasets.The results showed that MODIS reflectance in visible light band positively correlated(P0.05)with the ground photographic digital number,in which the most significant correlation appeared between MODIS reflectance in 500 mspatial resolution and the ground photographic digital number.Nevertheless,TM/ETM+reflectance did not significantly correlate(P0.05)with the ground photographic digital number.The positive correlation between MODIS Normalized Difference Vegetation Index(NDVI)and relative greenness index from ground photography(G%)was obviously higher than those between other vegetation indices and greenness indices.Errors between phenological occurrence dates derived from remote sensing and ground photography data were mostly within 7days.In conclusion,the reliability of remote sensing phenology monitoring by means of ground photography was of crucial for selecting appropriate remote sensing data source and phenological monitoring index.

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.
