Abstract

fetched live from OpenAlex

Abstract We introduce a measure of (central) symmetry for a convex body K in ℝ n based on the volume of the harmonic mean of K and −K (that is, the body whose gauge is the average of the gauges of K and −K), and compare it to other classical volumetric measures of symmetry. We prove sharp inequalities between the volume of the harmonic mean of K and −K and the volume of their intersection, and we show that, if K is in John’s position, then the harmonic mean of K and −K has the smallest volume exactly when K is the Euclidean ball and the largest volume exactly when K is a simplex.

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.
