Abstract
A stroke is a neurological condition in which the brain is deprived of oxygen and nutrients due to the reduced supply of blood it. One of the signs of stroke is weakness on one side of the body. This weakness can be captured using a pressure sensor mattress which captures the patients position on the mattress. In this paper, a LSTM model is developed that uses pressure data and classifies between left and right sided stroke induced motor weakness. Data is collected from 25 post stroke patients over a course of 48 hours in a clinical setting. An average recall and precision of 69.85% and 62.76% is achieved for binary classification. A per patient average recall of 67.82% ± 18.25% is achieved.

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
