Abstract
<p>A novel method for remote heart rate sensing via standard broadband<br />video is proposed. Points are stochastically sampled from the<br />cheek region and tracked throughout the video, producing a set<br />of skin erythema time series. From these observations, a photoplethysmogram<br />(PPG) is estimated via Bayesian minimization, with<br />the required posterior probability estimated through an importanceweighted<br />Monte Carlo approach. From the estimated PPG, an estimated<br />heart rate is produced through frequency domain analysis.<br />Results indicate improved accuracy over current state of the art<br />methods.</p>

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
