Abstract

fetched live from OpenAlex

It is possible for physicians to review electronic lab results in the format of the sending lab and, as well, to see them using advanced visualization techniques. When lab results for a particular patient are reviewed by a physician, they must be integrated with other lab results and other issues of the patient. Viewing the results can present a number of difficulties. One problem relates to normal ranges that can change over time and can be different when sent by different labs. This is not an issue when results are printed but when the results are graphed with their normal range displayed, distortions often prompt questions from patients who are shown the results. There are also situations were it is important to review a cluster of four or five different tests to properly understand the clinical situation. Tests in the cluster, however, can have interrelated result values that differ by orders of magnitude. Normalization, which can be used to scale the graphs, has been proposed in the past but not gained any popularity. The benefits of this approach are discussed.

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.
