Abstract

fetched live from OpenAlex

Multimedia systems utilize multiple media streams, each of which have different confidence levels in accomplishing various detection tasks. For example, in a multimedia surveillance system, one would usually have higher confidence in an audio stream compared to a video stream for detecting human shouting events. The pre-computation of these confidence levels is cumbersome especially when new media streams are dynamically added to the system. This paper proposes a novel method, which dynamically computes the confidence levels of new streams based on the past history of their agreement/disagreement with the already trusted streams. To demonstrate the utility of the proposed method, we provide the experimental results for detecting events in a multimedia surveillance scenario.

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.
