Abstract

fetched live from OpenAlex

Steady improvements in bandwidth offerings over wireline and most recently even wireless networks has helped the emergence of so-called Over the top (OTT) services, that is, quality-sensitive applications which adapt to device and network conditions to deliver a service with a suitable quality for its users. Unlike traditional multimedia deployed over quality-enabled networks, OTT services cannot rely on guaranteed quality levels from the network, nor on feedback from the network on achievable quality. They depend on their own feedback to report on the quality received and infer which mishaps may be occurring at the network level. We present here an algorithm which manages the quality level of a live video stream using a standard feedback mechanism to adapt throughput to varying network conditions. It uses redundancy to both protect traffic from losses but also as a form of safety margin to both predict available throughput and isolate random fluctuations. We also show the performance of the algorithm compared to alternative solutions.

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.
