Abstract

fetched live from OpenAlex

Abstract In this article, the Fisher information is expressed in terms of the (reversed) hazard rate and several illustrated examples are given for its advantage. The concept is explored in the case of Type I and Type II censoring and characterization results are obtained for a class of distributions in which the (reversed) hazard rate factorizes into a function of the observation and a function of the parameter. Also, the Fisher information in the weighted models is studied with special emphasis on the exponential family of distributions. Finally, some concluding remarks are provided which help the practitioner to choose between the proposed procedure and the existing procedures.

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.
