Abstract

fetched live from OpenAlex

Motivated by the problem of adaptive resource management in decentralized sensor networks, the paper derives an algorithm for the distributed computation of the conditional posterior Cramér-Rao lower bound (PCRLB) for nonlinear tracking applications as an alternative to the non-conditional (conventional) PCRLB. Using the proposed conditional bound, a decentralized adaptive sensor-selection algorithm is then developed with the objective of dynamically activating a subset of observation nodes to optimize the network's performance. Our Monte Carlo simulations verify the superiority of the proposed decentralized PCRLB based sensor selection approach in bearing only tracking applications over its conventional counterparts.

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.
