Abstract

fetched live from OpenAlex

Summary form only given. To achieve error resilience, digital communication systems typically partition a data file into blocks of samples in the time domain which represent small cohesive segments of the input source, be it image, video or audio. We consider the problem of packing a set of embedded bitstreams B/sub k/ into M packets of payload L. Optimal packetization is to select ML bits to fill in M packets while satisfying certain alignment constraints that are imposed by error resilience designs, and at the same time minimizing the distortion. Just as source and channel coding have conflicting objectives of removing and adding redundancy, error resilience via packetization will somewhat reduce the rate distortion performance of the compression code when the transmission is error free. Our goal is to minimize such losses of coding efficiency.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
