Abstract

fetched live from OpenAlex

We study the eigenvector mass distribution of an N×N Wigner matrix on a set of coordinates I satisfying |I|⩾cN for some constant c>0. For eigenvectors corresponding to eigenvalues at the spectral edge, we show that the sum of the mass on these coordinates converges to a Gaussian in the N→∞ limit, after a suitable rescaling and centering. More generally, we establish a central limit theorem for observables of the form ⟨u,Au⟩, where u is an edge eigenvector and A is a deterministic matrix with Tr(A2)⩾cN. The proof proceeds by a two moment matching argument. We directly compare edge eigenvector observables of an arbitrary Wigner matrix to those of a Gaussian matrix, which may be computed explicitly.

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.
