Abstract

fetched live from OpenAlex

A procedure to regulate the feedback signals of multiple sensors, at different rates, inside of a low-level control loop using data fusion has been developed and tested in simulation. The procedure is independent of the fusion method, and applicable to sensors with widely different sampling rates. Thus, it permits the use of "secondary" sensors, which may be available to the system for other purposes, to monitor sensor fault or failure occurrence, provide smooth transition for the system on fault, and provide a way to dynamically reconfigure the sensing system based on sensor signals uncertainty. In this procedure, sensor signals are time-correlated using Kalman filters, before being fused together. To regulate the fused feedback signal when there is no data available from the slower sensors, a Kalman filter is used to observe and generate a prediction of the fused measurement signal in place of the slower sensors measurement. Since the slow sensor lag compensation and fused measurement stabilization are independent of the fusion process, any real-time data fusion process can be used with this procedure.

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.
