Abstract

fetched live from OpenAlex

In this paper, we propose a novel signaling scheme and corresponding noncoherent fusion rules for wireless sensor networks. In the proposed scheme, sensors transmit censored decisions to the fusion center using signature vectors. To improve bandwidth efficiency the signature vector length can be chosen smaller than the number of sensors in the network resulting in non-orthogonal sensor channels. We derive the optimum noncoherent likelihood-ratio (LR) based fusion rule as well as a low-complexity energy-based fusion rule for the considered signaling scheme and Rayleigh fading. Furthermore, the performance of the energy-based fusion rule is analyzed. Numerical and simulation results show that with the proposed scheme significant improvements in bandwidth efficiency are possible at the expense of a small loss in power efficiency.

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.
