Abstract
In this paper, the problem of selecting an appropriate number of forward error correction (FEC) packets under given channel and network conditions is formulated as an optimization problem and two heuristic algorithms are proposed to find the solution. These heuristic algorithms are used for selecting the parameters of FEC scheme under a given maximum number of automatic repeat request (ARQ) retries, to achieve higher visual quality and efficient transport of multimedia applications over an IEEE 802.11 wireless channel. The proposed algorithms are: adaptive linear FEC (ALFEC) and adaptive exponential FEC (AEFEC), where the number of FEC packets respectively decreases linearly and exponentially, as the sender's queue increases. Simulated performance of the proposed algorithms is compared against those for the existing static and dynamic FEC generation schemes. It is found that the proposed heuristic algorithms outperform the other existing schemes in terms of system efficiency and provides comparable peak-signal-to-noise-ratio (PSNR) gain.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
