Abstract

fetched live from OpenAlex

Summary form only given. This paper presents a framework to effectively compress sets of images in a lossless manner. An image set is represented as a graph and its minimum spanning tree is computed to decide which images and differences to encode. The Centroid scheme and the previous MST scheme can both be represented as a spanning tree in our graph. Thus, the scheme is guaranteed to be no worse than these previous schemes. In fact, the framework provides the best lossless compression for all schemes that consider interimage redundancy between two images in a set. Experimental results show that the new MST method always produces the best result regardless of the properties of the image sets. In some cases, the first-order entropy of the image set using our scheme results in a 29% improvement over the traditional scheme of compressing each image individually.

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.
