Abstract

fetched live from OpenAlex

This paper proposes a new design of a MAP decoder suitable for ASIC. The decoder architecture is parallel and pipeline, which makes the design applicable to bit rate communication systems. Max-log-MAP algorithm, which offers a good compromise between performance and complexity, is selected for implementation. One of the components of this algorithm, namely, the transition probability (/spl gamma/) calculation unit is studied and a new low complexity design of this unit is proposed. Overall decoder design is flexible to the transmission block lengths, which makes it suitable for variable length transmission systems.

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.
