Abstract

fetched live from OpenAlex

We establish Tracy-Widom asymptotics for the partition function of a random\npolymer model with gamma-distributed weights recently introduced by\nSepp\\"al\\"ainen. We show that the partition function of this random polymer can\nbe represented within the framework of the geometric RSK correspondence and\nconsequently its law can be expressed in terms of Whittaker functions. This\nleads to a representation of the law of the partition function which is\namenable to asymptotic analysis. In this model, the partition function plays a\nrole analogous to the smallest eigenvalue in the Laguerre unitary ensemble of\nrandom matrix theory.\n

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
