Abstract

fetched live from OpenAlex

In this study, we have been developing a health check device, “Pulse Wave Checker” which is used to obtain indices representing the autonomic nervous function based on photoplethysmogram. This device aims at evaluation of the function easily and safely even at temporary houses after the Disaster. A respiratory control task has been used to quantify the effects of the task on the change in the autonomic nervous characteristic. This paper will discuss the adequacy of the proposed method on the basis of experimental results obtained from 71 subjects consisting of old and young groups. As a result, it suggests that a few kinds of indices representing the dynamic characteristics between the pulse transit time and the heart rate can evaluate the change in autonomic nervous function.

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.

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.
