Abstract

fetched live from OpenAlex

After receiving a piece of evidence Π, intelligent agents adapt their belief state. Knowing the belief state of several sensor agents, a fusion agent forms its own belief state. A belief state (old or new) is characterized by numbers μ(A) attached to subsets A of the universe of worlds. (Usually μ(A) is interpreted as that part of the belief of an agent in the sentence "the actual world belongs to A" and not in any sentence "the actual world belongs to a strict subset of A".) In this paper we study how fusion agents treat changes of belief state of sensors. Two kinds of fusion are considered: the averaging by convex combination, and Dempster type conjunctive rules of combination. We establish that there is no coherent treatment, at the fusion agents' level, that is compatible with both kinds of fusion. To deal with better detection, a mixed structure involving intermediate supervision agents is proposed.

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.
