Abstract

fetched live from OpenAlex

The objective of this study is to produce a land cover classification dataset for the whole of Asia using a NOAA AVHRR 1-km dataset. Ground truth data were mainly collected from existing thematic maps, which were obtained from members of the Land Cover Working Group (LCWG) of the Asian Association on Remote Sensing (AARS). Classification was mainly based on cluster analysis of the monthly ratio of surface temperature to Normalized Difference Vegetation Index (NDVI) for seven months from April to October 1992. Additional variables, such as DEM, the maximum monthly composite NDVI in a year, and the minimum monthly composite NDVI in a year were also used in the classification processing. A CD-ROM including the land cover classification dataset has been published.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
