Abstract

fetched live from OpenAlex

Conventional methods for assessing levels of sensory-motor impairment in stroke patients are inherently subjective and dependent upon the clinician's own observations and opinions. In this study, 93 control and 63 stroke subjects underwent robotic assessment to gauge sensory-motor impairment. Multiple statistical data normalization and dimensionality-reduction measures were evaluated, using four different classifier types, in order to derive an optimal feature vector for the purpose of distinguishing stroke from control subjects. The optimal feature vector was then utilized to train a committee of classifiers for the purpose of recombining data from several traditional sensory-motor assessment scores into a KINARM specific assessment metric. We were able to create a training vector capable of distinguishing between stroke and control subjects with high accuracy, and demonstrated that the committee of classifiers assigned consistent scores to patients of similar levels of impairment.

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.
