Abstract

fetched live from OpenAlex

Abstract Coring of shell-midden sites provides a regional chronology of site settlement in the Namu vicinity on the central coast of British Columbia. Coring proved an accurate and cost-effective alternative to traditional test-excavation, and its application in only two short field seasons doubled the number of sites tested in this region. The dating of basal cultural deposits from the cores shows initial occupation of sites ranging from 10,000 to 800 B.P. These dates exhibit a strong linear relationship with the current elevation of deposits above average high tide, suggesting that the settlement history of known shell-midden sites in this region is strongly linked to gradual long-term decline in relative sea levels.

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.
