Abstract

fetched live from OpenAlex

The current scale of online video streaming requires hardware accelerated video transcoding solutions. Historically, hardware solutions have been excellent at offloading the computationally intensive tasks from CPUs, but often came with the penalty of being inflexible and not quickly adaptable to emerging market trends. We are presenting an architecture, which maintains all the benefits of hardware acceleration but also adds an unparalleled level of programmability and flexibility. This architecture supports a wide spectrum of markets ranging from ultra-low latency encoding all the way to high quality video on demand (VOD) markets with only firmware changes. These capabilities are achieved by a strategic combination of built-in hardware acceleration components and many embedded CPUs that have full control over the video encoding pipeline flow. This architecture not only provides deterministic timing, which is critical for ultra-low latency transcoding, but it also offers flexibility and programmability allowing robust product roadmaps through simple firmware updates.

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.
