Abstract

fetched live from OpenAlex

A basic reasoning problem in dynamic systems is the projection problem: determine if a formula holds after a sequence of actions has been per-formed. In this paper, we propose a tractable1 so-lution to the projection problem in the presence of incomplete first-order knowledge and context-dependent actions. Our solution is based on a type of progression, that is, we progress the ini-tial knowledge base (KB) wrt the action sequence and answer the query against the resulting KB. The form of reasoning we propose is always log-ically sound and is also logically complete when the query is in a certain normal form and the agent has complete knowledge about the context of any context-dependent actions. 1

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.
