Abstract
Abstract Dementia reduces a person's ability to perform activities of daily living (ADL) because of the difficulty of remembering the proper sequence of events that must occur and how to use the required tools. The current solution is to have a caregiver continually provide verbal prompts. Family caregivers find assisting their loved ones to be particularly upsetting and embarrassing as it necessitates invasion of privacy and role reversal. It has been suggested that dependence on a caregiver might be improved using a cognitive orthosis that provides needed reminders and monitors progress. This paper will report on the results obtained from an efficacy study conducted with such a device. The COACH is a prototype of an intelligent computerised device that was developed to assist people with dementia complete ADLs with less dependence on a caregiver. The device was developed using a personal computer and a single video camera to unobtrusively track a user during an ADL and provided pre-recorded verbal prompts when necessary. It was tested with 10 subjects with moderate to severe dementia during handwashing in a study lasting 60 days. These trials showed that the number of handwashing steps that the subjects were able to complete without assistance from the caregiver increased overall by approximately 25% when the device was present. Individual changes ranged from approximately 10-45%. These changes were proven to be statistically significant at a 99% confidence level.

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
