Abstract
Analog current-mode circuits are presented for implementing min-sum (MS) iterative decoders, which are used for decoding low-density parity-check (LDPC) codes and turbo codes. While previously reported analog decoders rely on the exponential characteristics of bipolar or subthreshold MOS transistors, proposed circuits can also be used for designing strongly inverted CMOS analog decoders. A proof-of-concept 80-Mb/s CMOS MS decoder is designed and fabricated that consumes the least reported energy per bit and operates at least six times faster than previously reported CMOS analog decoders.
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 imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
