Abstract
A key challenge in extending vision-linguistic models to new video domains is curating large annotated datasets. We propose a framework that leverages videos with noisy linguistic descriptions, such as sports broadcasts, to train a model using an uncurated dataset. We introduce an unsupervised model that uses the corpus membership between a target and an auxiliary corpus to assign a relevance probability to the linguistic description of examples in the target domain. We examine these probabilities to evaluate the effect of noisy data in the video-text retrieval task. Our framework provides a domain-invariant recipe for enhancing multi-modal datasets by reducing the noise without requiring the costly manual curation effort. We show that our unsupervised model improves the performance of the video-text retrieval model using readily available hockey broadcast videos with closed-captioning. Furthermore, we propose a multi-modal cross-correlation objective function to obtain additional performance gains. We showcase our proposed framework in the context of a new multi-modal dataset of temporally labeled hockey videos with noisy textual descriptions.

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 it
