Abstract

fetched live from OpenAlex

Rapid development and deployment of GPU based computation has led to an improvement in diffusion generation of video and images. Further, a rapid reduction in the effective cost of compression using NNC techniques provides opportunities to compress images and videos in new ways. The overall structure of diffusion based generative video and images is leveraged to take advantage of the compressed latent to lower overall compression costs and latency. This paper presents an architecture to compress a latent for transmission and reduce overall latency and cost as compared to alternatives using traditional Codecs or NNC on the raw image. It explores a proof of concept based on image compression of a latent. It further presents computational cost, quantitative and perceptual quality, and latency for this architecture as compared to the alternatives.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
