A decision support framework for clinical needle EMG
Bibliographic record
Abstract
A framework for a decision support system (DSS) is introduced. This framework supports the exploration of quantitative electromyographic (QEMG) data acquired using a concentric needle electrode and decomposed using the DQEMG program. This DSS has been constructed by marrying a statistically based fuzzy inference system (FIS) with a user interface, allowing drill-down exploration of the underlying statistical support, providing an exceptionally transparent access to both the rule based inference as well as the underlying statistical basis for the rules. The FIS is constructed through a Pattern Discovery based analysis of training data. Such an analysis yields a rule base characterized by simple explanations for any rule or data division in the extracted knowledge base. The reliability of a fuzzy inference is well predicted by a confidence measure that determines the probability of a correct suggestion by examination of values produced during the inference calculation. The combination of these components provides a means of supporting the characterization of neuromuscular disorders in a clinical environment, providing the transparent support required to allow a clinical user to confidently incorporate the automatic suggestions provided by this framework into a larger decision context. Specific data examples based on the characterization of QEMG data are used to demonstrate the principles of the system.

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.
