Abstract

fetched live from OpenAlex

In this paper, a Quality Metric (QM) called the Artifacts-based Video Quality Metric (AVQM) is proposed. Three avenues of innovation are exploited. 1) The context of the video is used so that artifacts in different surroundings are treated differently. 2) A measurement is made of the block-flashing artifact. 3) A non-linear method of combining artifact measures using fuzzy methods is employed. Simulation results indicate that these significantly improve performance.

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.

Full frame distilled prediction

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.
