Abstract

fetched live from OpenAlex

In this paper, we present a new independent component analysis mixture vector quantization (ICAMVQ) method to summarize the video content. In particular, independent component analysis (ICA) is applied first to explore the characteristics of video data and build a compact 2D feature space. A new ICAMVQ method is then developed to find the optimized quantization codebook in ICA subspace. The optimal codebook size is determined by Bayes information criterion (BIC). The frames that are the nearest neighbors to the quanta in the ICAMVQ codebook are sampled to summarize the video. A 2D kD-tree is employed to index the feature space and accelerate the nearest-neighbor search. Experimental results show that our method is practically effective and computationally efficient to build a video summarization system.

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.
