Abstract

fetched live from OpenAlex

In the examples in later chapters we use parametric models almost exclusively. These models are used to incorporate a key element of statistical thinking: the explicit recognition of uncertainty. In frequentist settings imprecise knowledge about the value of a single parameter is typically expressed through a collection of confidence intervals, or equivalently by computation of the P-values associated with a set of hypotheses. If prior information is available then Bayes' theorem can be employed to perform posterior inference.

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.
