Decentralized spectrum learning and access adaptive to channel availability distribution in primary network
Bibliographic record
Abstract
We consider the effect of the mean availability distribution of primary channels on the performance of distributed learning and access policies, and develop a distributed learning and access policy that is effective in a wide range of primary channel conditions. We first extend the recently proposed BLA algorithm to distributed online learning of underlying primary channel availabilities, and modify the existing access policies to form BLA-ρRANDand BLA-DLF policies. By analyzing the distributed access collision mechanism offered by the ρRANDand DLF policies [1], [2], we identify how different mean channel availability distributions can impact the effectiveness of each policy. In light of this, we propose DSLA policy that adapts to different channel availability distribution conditions. Based on a closeness factor we propose, the DSLA policy automatically switches between the underlying learning policies, as well as the access policies, to determine which policy is most effective for a given primary channel condition. Simulation studies show that our proposed DSLA policy is effective in providing a good performance for a wide range of primary channel availability distributions.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
