Abstract
This paper presents a method for joint decoding of JPEG2000 bistreams and Reed-Solomon codes in the context of unequal loss protection. When the Reed-Solomon decoder is unable to retrieve the erased source symbols, the proposed joint decoder searches through the set of possible erased source symbols, making use of error resilience features of JPEG2000 to retrieve correct symbols. The joint decoder can be used as an add-on module to some of the existing schemes for unequal loss protection, and can improve the PSNR of decoded images by over 10 dB in some cases.

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
