Abstract
A method for quantifying 50/60Hz power line interference in surface electromyography signals is proposed as part of an ongoing research project, CleanEMG, that aims to provide open source, user friendly methods to assess the quality of surface electromyographic signals. The quantification method is based on interpolating the signal spectrum about its 50/60Hz components to estimate the signal, and then the power line interference. Once these constituents are differentiated, a signalto-noise ratio may be estimated. A simulation was used to determine when noise due to error in the estimation process surpasses noise from the power line interference. This can be interpreted as the threshold point beyond which removing power line interference via the interpolation method would result in adding noise to the signal. Results indicate a signal-to60Hz-noise threshold of about 9dB.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
