Abstract

fetched live from OpenAlex

For a given body ofpossible belief evidential data, a processing objective is to glean the most correct knowledge f.om such data (but not more). The author introduced a new methodology of combining independent multi-source beliefs in 2002. This generalized belief fusion algorithm, depending on the probability proportionality weighting functions used, is shown to be equivalent, in the probability estimate, to the DempsterShafer (D-S,) theory of evidence, the Firsen-Mahler Modified Dempster- Shafer (MDS) theory and other new fusion methodologies that will converge faster to correct results. A more computationally friendly representation of the generalized belief /usion algorithm is given. A numerical example comparing five belief fusion variants is presented for the same inputs. This article also introduces a pignistic probability transform proportional to the normalized plausibility pansform.

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.
