Abstract

fetched live from OpenAlex

The selection of the appropriate fusion algorithm depends on the underlying data fusion architecture. In the centralized scheme, the sources are known to be independent and the Kalman filter provides an optimal solution. Unfortunately, in the decentralized architecture, the sources become correlated and the Kalman filter cannot be applied. The covariance intersection method has been proposed as a solution to the problem of decentralized data fusion. However, it results in a decrease in performance. A new fusion algorithm (largest ellipsoid approach) that avoids both of the inconsistency of the Kalman filter and the lack of performance of the covariance intersection is proposed. The superiority of the proposed approach is illustrated using the target's tracking problem.

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.
