Abstract

fetched live from OpenAlex

Achieving k-coverage in wireless sensor networks has been shown before to be NP-hard.We propose an efficient approximation algorithm which achieves a solution of size within a logarithmic factor of the optimal.A key feature of our algorithm is that it can be implemented in a distributed manner with local information and low message complexity.We design and implement a fully distributed version of our algorithm.Simulation results show that our distributed algorithm converges faster and consumes much less energy than previous algorithms.We use our algorithms in designing a wireless sensor network for early detection of forest fires.Our design is based on the Fire Weather Index (FWI) System developed by the Canadian Forest Service.Our experimenta.1 results show the efficiency and accuracy of the proposed system.To the wandering sou1 of the desert "We feel free because we lack the very hnguage to articulate our unfreedon."-Slavoj Zizek I am deeply indebted to my senior

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.
