Abstract

fetched live from OpenAlex

Intra refresh is a very common tool to improve the error resilience performance for video encoding.Too many intra macroblocks will harm the compress efficiency.To achieve the optimal end to end quality for real video transmission system,it is crucial to make a tradeoff between intra refresh rates and compress efficiency.In this paper,by analyzing the affection of other factors on video qualities,i.e.quant parameter(QP) and channel conditions,we propose a cross layer based scheme to jointly optimize the intra refresh rate,QP,and adaptive modulation and coding(AMC) scheme at the physical layer to minimize the video distortion at the receiver.The simulation results show that the error resilience performance is greatly improved,and the PSNR gains from 0.5 to 7dB can be achieved under different channel conditions.

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.

Not 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.
