Abstract

fetched live from OpenAlex

We present a method to generate models for trees in which we first create a weighted graph, then places endpoints and root point and plan least-cost paths from endpoints to the root point. The collec-tion of resulting paths form a branching structure. We create a hier-archical tree structure by placing subgraphs around each endpoint and beginning again through some number of iterations. Power-ful control over the global shape of the resulting tree is exerted by the shape of the initial graph, allowing users to create desired variations; more subtle variations can be accomplished by modify-ing parameters of the graph and subgraph creation processes and by changing the endpoint distribution mechanisms. The method is capable of matching a desired target structure with a little manual effort, and can easily generate a large group of slightly different models under the same parameter settings. The final trees are both intricate and convincingly realistic in appearance.

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.
