Abstract

fetched live from OpenAlex

We study low-delay streaming codes for erasure channels in point-to-point and multicast scenarios. We consider a sliding window erasure channel which captures the temporal correlation in packet losses observed in real channels. This correlation is often modelled using statistical channels such as Gilbert-Elliott channel. In the point-to-point case, we provide a new class of codes, Embedded Maximum Distance Separable (EMDS) codes, which recovers from channels introducing a mixture of burst and isolated erasures. Moreover, we propose a technique that extends point-to-point codes for the multicast scenario with two receivers that tolerate different delays, T1and T2. The multicast codes opportunistically decode packets with short delay T1when the channel is relatively better and with long delay T2when the channel is worse. Simulations over multicast Gilbert-Elliott channels show that EMDS codes outperform other streaming codes for both users.

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.
