Abstract

fetched live from OpenAlex

Abstract In recent years, with the rapid development of the Internet, multimedia information and its processing technology began to flourish. Today, smart terminals represented by smartphones are becoming more and more popular, and the era of mobile Internet has arrived. While changing the way multimedia information is composed and accessed, the Internet has also led to explosive growth in the amount of multimedia data. Short videos are often used as a social medium and spread on short video social platforms. Despite their limited length, short videos can always depict a relatively simple but complete story in a relatively short time. At the same time, they are always produced by non-professional users. We propose a short video feature presentation model MVRLR based on low-rank representation learning for multiple perspectives, which not only maximizes the complementarity and correlation among multiple perspectives, but also learns the subspace structure of lower dimensional eigenvalues through low-rank embedding; on this basis, we introduce a robust elastic regularization network to learn the potential label matrix to prevent the overfitting problem. Second, to further solve the high-dimensional and nonlinear problems of the data, the proposed model is extended to a multilinear form by constructing a new eigenmatrix through kernel functions to improve the model's ability to deal with high-dimensional nonlinear problems. We conduct several experiments to confirm that the model performs better than other baselines.

Full frame distilled prediction

Teacher imitation

Not 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.
