Abstract

fetched live from OpenAlex

The decomposition of a myoelectric (ME) signal into its constituent motor unit action potentials (MUAPs) can be considered as a classification problem. The choice of features used can affect the classifier performance. Using an information measure applied to clustering results the most discriminative features from a set of 32 time samples were selected. The full set of time samples, information-selected features, linear discriminant analysis and principle component analysis were used for the supervised classification of real MUAP data. Results suggest that the sets of information-selected features were an efficient representation of lower dimension which provided high accuracy classification with reduced computational requirements.

Full frame distilled prediction

Teacher imitation

Not 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.
