Abstract

fetched live from OpenAlex

We consider the problem of distributed rate adaptation among multiple video streaming sessions over the Internet from a decision-theoretic and computational intelligence point of view, and we design a multi-objective optimization model for network resources, seeking a fair and efficient distribution of end-users' Quality of Experience (QoE). A social welfare function is developed to capture both fairness and efficiency objectives at the same time. Then, assuming a common altruistic goal for all network users, we propose a Decentralized Partially Observable Markov Decision Process (Dec-POMDP) model for finding the optimal network bandwidth allocation that leads to social welfare maximization. We show that the resulting optimal policy for the proposed model outperforms TCP-Friendly Rate Control (TFRC) protocol in terms of total utility and fairness.

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.
