Abstract

fetched live from OpenAlex

Apnea is a condition characterized by the spontaneous cessation of respiratory airflow during sleep. The current gold standard for the diagnosis of apnea is the manual analysis of cardiorespiratory data records by trained personnel; this restricts the study of apnea to the clinical setting, and is costly, time-intensive, subjective, and prone to human error. We have developed a monitor that non-invasively acquires, classifies, annotates and displays patient cardiorespiratory data in an on-line and fully-automated manner. The monitor is robust, portable and battery-operated and has a graphical user interface for patient monitoring by a clinician. The unit has received approval for use in the postoperative recovery room at the Montreal Children's Hospital as a point-of-care diagnostic tool to monitor infants for post-operative apnea.

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.
