Abstract

fetched live from OpenAlex

Abstract The recent advent of low magnification microwear analysis has allowed the efficient study of entire vertebrate faunas using only an optical stereomicroscope. Photographic visualization of microwear by this means has proven difficult, however, and, as a result, few high-resolution photos of low magnification microwear have been published. The repeatability of the method has also been questioned because low magnification microwear analysis involves the visual inspection of microwear features. We show that the use of high dynamic range imaging improves the visualization of microwear features in photographs and that using these photographs as a counting medium increases the repeatability of the method. We also show that counting from the photographs allows us to accurately classify ungulates as browsers, grazers, or mixed feeders.

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.

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.
