Abstract

fetched live from OpenAlex

Divide a Logarithmic Number of Times: Many algorithms repeatedly cut the input instance in half. A classic example is binary search (Section 1.4): You take something of size n and you cut it in half, then you cut one of these halves in half, and one of these in half, and so on. Even for a very large initial object, it does not take very long until you get a piece of size below 1. The number of divisions required is about log2(n). Here the base 2 is because you are cutting them in half. If you were to cut them into thirds, then the number of times to cut would be about log3(n).

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.
