Abstract

fetched live from OpenAlex

We introduce a probabilistic latent variable model for graphs that generalizes both the established graphon and stochastic block models. This naive histogram AHK model is simple and versatile, and we demonstrate its use for disparate tasks including complex predictive inference usually not supported by other approaches, and graph generation. We analyze the tradeoffs entailed by the simplicity of the model, which imposes certain limitations on expressivity on the one hand, but on the other hand leads to robust generalization capabilities to graph sizes different from what was seen in the training data.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
