Abstract

fetched live from OpenAlex

In this paper, we present some results of a new regularization method for systems of ill-posed problems related to the direct and inverse problems of electrocardigraphy; more precisely, for given matrix H of measured epicardial potentials and matrix B of measured thoracic potentials, we search for the best transfer matrix in the sense that it is simultaneously good for direct and inverse problems. This concept has permitted us to calculate an optimal value a = for the first order Tykhonov regularisation parameter. Results for direct and inverse problems with (a = a,,,) are compared with results for CY = 0 (standard linear regression) and CY = lo-'.

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.
