Abstract

fetched live from OpenAlex

Abstract A “Bayesian belief network” is a directed acyclic graph that specifies how stochastic variables in a complex system interact. The joint distribution is equal to the product of a set of conditional distributions. There is one conditional distribution for each node of the graph and each conditional distribution is conditioned on the parents of the corresponding node. Unlike Markov random fields, Bayesian networks do not require a partition function.

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.
