Abstract

fetched live from OpenAlex

Cognitive radio technology necessitates accurate and timely sensing of the primary users' activity on the chosen set of channels. We assume that sensing is performed by a number of nodes in a personal area network (PAN), and that sensing results are collected by the PAN coordinator which combines them to form a coherent channel map. The simplest selection procedure is a simple random choice of channels to be sensed; to reduce the delay in detecting the end of spectral opportunities, different sensing probabilities are assigned to active and inactive channels. To improve the accuracy of the sensing process even further, we propose to modulate the sensing probabilities according to the duration of active/inactive periods, or according to the time of last sensing event. The paper analyzes the performance of these policies and discusses the range of parameters in which they lead to a reduction of sensing error.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
