Audio-Visual Fusion And Conditioning With Neural Networks For Event Recognition
Bibliographic record
Abstract
Video event recognition based on audio and visual modalities is an open research problem. The mainstream literature on video event recognition focuses on the visual modality and does not take into account the relevant information present in the audio modality. We propose to study several fusion architectures for the audio-visual recognition task of video events. We first build classical fusion architectures using concatenation, addition or Multimodal Compact Bilinear pooling (MCB). Then, we propose to create connections between visual and audio processing with Feature-Wise Linear Modulation (FiLM) layers. For instance, the information present in the audio modality is exploited to change the visual classification behaviour. We found that multimodal event classification performance is always better than unimodal performance, whatever the fusion or conditioning method used. Classification accuracy based on one modality improves when we add the modulation of the other modality through FiLM layers.

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.
