Abstract

fetched live from OpenAlex

To improve the reliability of dynamic multiple wireless body area networks (WBANs) system, it is indispensable to comprehensively consider the interference mitigation and user data differences. In this paper, we study a multi-WBAN system, where sensors receive radio frequency (RF) signals from the access point (AP), then transmit the monitoring sign to the sink node. Considering the dynamic network topology and the individuality of users, we propose a data-driven wasser-stein distributionally robust weight-based joint power allocation (DW-JPA) scheme. In particular, we formulate a sum-weighted transmission rate maximization problem by optimizing dynamic weight and transmit power ratio subject to the data transmission and energy limitation constraints. We divide the problem into dynamic weight subproblem and transmission power control subproblem. We utilize the collected physiological data to predict the optimal actual weight assignment. Then, we quantify the criticality of sensors and build an ambiguity set based on wasserstein distance for probability distributions of the critically. In essence, the optimal weight is obtained by using the distributionally robust optimization (DRO) method. Furthermore, due to the non-convexity of the power control subproblem, we convert the subproblem to a difference of convex (DC) problem and use an iterative algorithm to alternately optimize the power ratio. The results reveal that the proposed scheme achieves a significantly higher weighted transmission rate with physiological data compared with traditional schemes.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
