Abstract

fetched live from OpenAlex

Consider f θ to be a probability density function with parameter θ. A set of k populations can now be defined such that the ith population Π i is the set of density functions . This paper proposes a test, based on the ϕ-dissimilarity, of the hypothesis that a new individual from a population Π0 with a density function , belongs to the ith population. The probabilities of misclassification of the minimum ϕ-dissimilarity classification rule are also obtained. In this paper, it is assumed that the parameters and may be θ0 are unknown and must be estimated from a set of training samples. Explicit expressions for the hypothesis test and the probabilities of misclassification are derived for the case where the populations Π i consist of homoscedastic normal, as well as for gamma distributions.

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.
