Collaborative content synchronization through an event-based framework
Bibliographic record
Abstract
Web-based user-driven multimedia applications such as Facebook, Flickr, YouTube, and MySpace have gained enormous popularity in recent years and have enabled the sharing of billions of multimedia objects. Multimedia files, especially images and videos, have a natural chronological ordering based on capture date and time. However, in most cases capture information is no longer available once images have been uploaded, emailed, or edited. In this paper, we focus on the problem of adding groups of images with missing temporal information (but ordered temporally) into a primary, organized image collection. We formulate the problem of adding images to an existing collection as a discrete optimization problem in which the objective function incorporates intuitive notions of temporal ordering and similarity with the existing images. We use the event and sub-event structure of the collection to identify potential matches. Specifically, we maximize the sum of similarity scores of the added images while maintaining their temporal order in an event-based framework. We also propose a greedy algorithm for adding images with the objective of minimizing the temporal spread of the images in the merged collection. We evaluate our algorithms using consumer image collections.

How this classification was reachedexpand
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.
