TRECVID 2012 GENIE: Multimedia Event Detection and Recounting
Bibliographic record
Abstract
Our MED 12 system is an extension of our MED 11 system [11], and consists of a collection of low-level and high-level features, feature-specific classifiers built upon those features, and a fusion system that combines features both through mid-level kernel fusion and score fusion. We have incorporated large number of audio-visual features in our new system and incorporated diverse types of standard and newly developed event agents which learn the salient audio-visual characteristics of event classes. The combination of additional features and newly developed powerful event agents improve our MED performance substantially beyond our MED 11 results. In addition, our MER 12 submissions reported recounting of specified clips for all five MER events and additionally provided MER results for all the clips detected by MED system. Our MER system generated recounting of detections based on CDR features and synopsis provided as part of the EventKits and DEV-T datasets. The MER evaluation results are promising for event-level discrimination, and indicated further improvement to be made for clip-level discrimination. 1

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
