Abstract

fetched live from OpenAlex

Unmanned aerial vehicles (UAVs) have been a provision for future wireless networks. However, limited backhaul capacity and power are bottlenecks for deployment and control of UAVs. To tackle these challenges, we propose a cache-enabled UAV networks to store popular files proactively to serve ground users and alleviate the backhaul burden. Taking account of the limited battery capacity, we propose an energy-efficient resource allocation and trajectory design algorithm to maximize the minimum achievable throughput among users. The formulated problem is a non-convex and mixed-integer optimization problem. To facilitate dealing with it, we decouple it into three subproblems and alternately solve them by jointly optimizing cache placement, transmit power, bandwidth allocation, and trajectory using successive convex approximation and block coordinate decent. The algorithm is proved to converge after finite steps of iterations. Numerical results reveal that our algorithm outperforms several baselines in terms of achievable throughput.

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.
