Abstract

fetched live from OpenAlex

Predictive vegetation mapping systems use a variety of remote sensing and other geospatial data in a mixture of empirical and biophysical models to predict vegetation characteristics. These systems are important tools for understanding and monitoring spatial patterns over the landscape. We have developed a system that partitions the geospatial data into resource gradients, indirect gradients and remotely sensed reflectance. These data are input to nearest neighbour classifiers and the resulting likelihoods are combined used Dempster's rule. We show that this system yields a more accurate classification than if the data were input to a single classifier.

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.
