Abstract

fetched live from OpenAlex

In this paper, we consider the problem of sensor resource management in decentralized tracking systems with asynchronous communication and sensor selection. Due to the availability of cheap sensors, it is possible to deploy a large number of sensors and use them to monitor a large surveillance region. Even though a large number of sensors are available, due to frequency, power and other physical limitations, only a maximum of certain number of sensors can be used by any fusion center at any one time. The problem is then to select the sensor subsets that should be used at each sampling time in order to optimize the tracking performance under the given constraints. In recent papers, we proposed algorithms to handle the above problem in centralized, distributed and decentralized architectures. However, in the paper for sensor subset selection for decentralized architecture, we assumed that all the fusion centers change their sensors at the same time, and their sensor change time interval is fixed and known. However, in general case, fusion centers may change their sensors at different time, and their sensor change intervals may not be fixed. In this case, the sensor management become more difficult. We have to decide when to change the subsets, and how to incorporate the changes made in the neighboring fusion centers in selecting the future sensor subsets. We propose an efficient algorithm to handle the above problem in real time. Simulation results illustrating the performance of the proposed algorithm are also presented.

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.
