Abstract

fetched live from OpenAlex

In the transmission process of a video signal over ATM networks, cells are inevitably exposed to delays, errors and losses due to the statistical multiplexing used in these networks. These phenomena effect the quality of the video signal and without adequate measures to control the propagation of the impairments the quality of the service may fall below acceptable levels. In the first part of this paper, we present an adaptive data partitioning (ADP) scheme. This scheme splits a video stream into a high priority and low priory substreams. In the second part of the paper, we propose a novel hierarchical packing scheme for the transmission of the two video substreams over ATM. The proposed packing scheme overcomes the problem that when no provisions are taking to properly pack a hierarchical-encoded video stream, the loss of a high priority ATM cell will result in the complete loss of the group of cells. Results for different video sequences and different bitstream split levels are given, showing the efficiency of our schemes.

Teacher imitation

Not 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.
