Abstract

fetched live from OpenAlex

We investigate the problem of compressive data aggregation in wireless sensor networks. We propose a data gathering scheme using Compressive Sensing (CS) by building up data aggregation trees from sensor nodes to the sink. Our problem aims at minimizing the number of links in the trees to minimize the number of overall transmissions. We formulate the problem of constructing aggregation trees for forwarding the compressed data to the sink as a mixed integer linear program (MILP) and present efficient algorithms to solve the problem. We show that our algorithms have outstanding performance and order of magnitude faster than the optimal model.

Full frame distilled prediction

Teacher imitation

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.
