Abstract

fetched live from OpenAlex

This paper presents a multichannel extension to the Poisson-based Bayesian statistical analysis of the net count rate in a sample. The derivation gives the net count rate probability density distribution in analytical form. In addition, it presents a Normal approximation that is appropriate when the number of counts is large. The new analysis can exhibit a lower false positive probability than methods that consider the counts for each peak separately or sum the counts for all the expected peaks associated with a radioactive substance.

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.
