Abstract

fetched live from OpenAlex

Clinical mobility tools have been shown to predict adverse outcomes in elderly patients, yet aren't used often enough to inform hospital staff on patient health.Integrated computing has therefore become increasingly important and is predicted to improve traditional healthcare.This thesis details the design of an algorithmic system to partially automate a mobility tool.Three pressure sensitive mats were set-up on a hospital bed frame, underneath a mattress.Thirty volunteers enacted five movements on the hospital bed; each movement representative of a different mobility score.These movements generated pressure data, and a system of algorithms was constructed in a decision tree to automatically classify data.The overall system yielded 96% accuracy, where the misclassifications were due largely to inconsistencies in volunteer performance.These results suggest that this algorithmic system is effective in distinguishing between the mobility enactments examined here, and emphasizes the potential for integrated computing to improve traditional healthcare.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
