Sleep Quality Index for Sensor Data in Eldercare Monitoring
Bibliographic record
Abstract
Early detection of health changes is important for the success of an aging population that prefers to live independently.Sleep is crucial for maintaining the cognitive and physical health of older adults.Poor sleep quality is common among the elderly with mild cognitive impairment (MCI), which is a transient state between healthy cognition and dementia.Monitoring sleep quality can provide valuable insights into the health trends of older adults, but current methods are uncomfortable and inconvenient.We instead use Ballistocardiography, an unobtrusive method of capturing time in bed, heart rate, respiration rate, and restlessness.We then propose a sleep quality index (SQI) that uses this data to assess the sleep health of older adults.This sleep index was evaluated on six residents with a total of 1165 days of sensor data.Our results demonstrate the effectiveness of the proposed method in capturing various health conditions, which are illustrated through detailed case studies.A comparative analysis further highlighted the relationship between health conditions and sleep quality, showing that residents with frequent health issues had a significantly lower SQI compared to healthier residents.This significant difference underscores the utility of the SQI as a sensitive measure for detecting and monitoring health-related changes in sleep quality among older adults.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
