Cognitive change measurement through driving navigation ability sensing and analysis
Bibliographic record
Abstract
This paper explores the detection of cognitive change in individuals by sensing a high cognition task (driving). The paper proposes algorithms for the analysis of a set of training trips by a driver to create baseline attributes and features for measurement of baseline navigational performance. Algorithms are proposed for the measurement of subsequent trips through comparison to the baseline performance attributes and the paper shows that trips with common coping mechanisms for cognitive decline can be identified and classified. Common coping mechanisms include use of familiar routes by backtracking to home or reduction in trip complexity through reduction in the variety of stops or in the number of stops are all identified. In addition, algorithms are proposed that identify changes in the navigation ability by indicating routing mistakes or poor choices. The paper shows that the measurement of patient performance can be compared to gold standard Google Maps based routing and navigation choices providing a baseline for a patient's cognitive performance and that cognitive change could be detected in behavior change relative to this baseline including less efficient trip planning, reduced trip complexity or less optimal navigation through use of inefficient but more familiar routes as coping mechanisms.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
