Abstract

fetched live from OpenAlex

The aim of this paper is to evaluate the decline of Atlas cedar forest in the Aures area by studying spatial data, using remote sensing and GIS. In order to show the dynamics of changes during different periods, a multi-data set of satellite images (Landsat: 1987, 1995, 2003 and 2016) have been processed (classification, geometric correction, and segmentation). The Normalized Difference Vegetation Index (NDVI) is adopted with a field request. The data analysis of the dynamic decline of the Atlas cedar allowed us to distinguish three areas (area of increase, of decrease and of no change). The areas of increase showed a great loss of Atlas cedar due to several factors.

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.
