Abstract

fetched live from OpenAlex

Data dependencies have been extensively studied in relational databases as they play a key role in the normalization process. On the other hand, probabilistic reasoning systems would not be practical without the notion of probabilistic conditional independence. In this paper, we present a detailed comparison of these two types of (in)dependencies. While past research has shown that multivalued dependency is a necessary but not sufficient condition for conditional independence, we show in particular that functional dependency is a sufficient but not necessary condition for conditional independence.

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.

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.
