Abstract

fetched live from OpenAlex

Asbestos reference slides with relocatable fields are effective in determining the fiber counting errors and evaluating intercounter precision and accuracy. The process is time consuming and expensive as it requires (a) the analysts to record the number and the positions of the fibers and (b) an experienced microscopist to determine the errors. A new parameter based on the discrepancies between the reported fibers and the verified fibers is being investigated for monitoring the quality of fiber counts. The discrepancies are related to the fiber counting errors. The new process requires the analysts to report only the fibers in each field examined.

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. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
